How to make a paper crane. Making crafts with children: do-it-yourself crane. Complex block system how to calculate power gain

Modern houses are being built higher and higher, and concrete blocks it doesn't get any easier. Therefore, if you think carefully, you can build a small crane with your own hands. The carrying capacity is not great, about two hundred kilograms, although, most likely, it can more weight lift, but it is not advisable to overload it. This design turns out to be completely collapsible, its components weigh approximately 20-30 kilograms, so assembling such a crane alone will not pose any special problems. In addition, such a structure is also easy to transport; the body of a Chinese pickup truck was quite suitable for this.

Let us remind you that we have previously published an article about a homemade tiny crane, for those who are interested, take a look.

Crane device

The cargo winch of my design is a worm gearbox with a 600 W electric drive, while the jib winch is a manual drive, organized on the same gearbox. Outriggers with screw stops are borrowed from construction supports. Drums for winches were machined from rotors from electric motors, suitable sizes were selected.

On the base of the mobile platform there are four wheels taken from the conveyor; thanks to them, the crane can be moved from one place to another without any problems, only if the outriggers of the crane are removed. This operation of removing and installing outriggers takes about five minutes. Therefore, the crane turns out to be quite mobile. But there is a small drawback: to move the crane, you need to lower the boom to zero, otherwise it becomes impossible to move the crane, since its balance is disturbed.

The boom itself has a length of 5 meters, the pipe was selected to be about 75 mm, and at the base of the boom itself there is a square profile made from two corners. There is also a portal for raising the boom, as well as a turning unit made from a hub from a truck. As a counterweight, a frame from a non-functioning machine was taken along with four tracks from a caterpillar mechanism. The brake in the winch in this case not provided because it is not necessary. There is also no brake in the turn itself, due to the fact that the speeds are very low, and, therefore, there is practically no inertia.

The minimum thickness of the metal used in my crane is about 3 mm; a rectangular pipe with dimensions of 85 * 50 and 85 * 55 is used as an outrigger and base as a whole - this is a kind of remains of agricultural equipment. The base of the tower is made of channel 200. A powerful bearing is inserted into the hook cage, therefore, the hook is able to rotate regardless of the pulley, to avoid overlap or twisting of the cable itself.

The stop screws are 400 mm long, as a result of which the crane can be installed very uneven surfaces.

There is one small drawback related to the wheels. The thing is that the wheels used in this case, when moving on loose soil, simply bury themselves in it; on a hard compacted surface - everything is fine. This faucet is considered one-time use, that is, after completing necessary work it is dismantled for scrap or for storage until the next use. That is why this design has a low load capacity and not very outstanding strength.

The manufacturing time for such a crane will take about three days, taking into account the preparation of all the necessary components. In this case, the gearboxes were made from whatever came to hand, transmission gearboxes They have such gear ratios as 1/30 and 1/35. , output parameters on the shaft are 600 W, capacitor capacity is 80 microfarads. All installations, excluding counterweights, weigh up to 250 kg, the cost of such a design is 4,000 rubles. Mostly the components used are borrowed from other equipment; only the cables and bearings are new.

Such a crane can easily lift one and a half hundred kilograms of cargo; we have not yet been able to move more at home.

Main components of a crane photo

Almost any construction site You can’t do without special equipment, especially a construction crane. He becomes an indispensable assistant when it is necessary to lift heavy loads to different heights.

Most people associate this technology with huge size, but there are many types of faucets that are ergonomic and compact.

You can even do some options yourself, saving personal savings during construction. In this article we will look at how to collect homemade faucet"Pioneer" for building a house.

Mini construction crane: scope of application

Mini taps enjoy in great demand. They are used during construction and repair work. Modern manufacturers offer innovative solutions in the manufacture of their products.

These devices are different:

maneuverability;
wide range of applications;
functionality;
ease of use.

Thanks to the presence of various attachments, various manipulations can be carried out with this technique.

Mini cranes, both purchased and assembled at home, are capable of working in the most hard to reach places: in cramped courtyards, dense urban construction, uneven sites, inside buildings and on roofs. Compact dimensions allow special equipment to even pass through single or double doors.

They are often used for thin, almost jewelry work. Manufacturers modern technology conducted an experiment with a matchbox that had to be moved from one place to another. At the same time, the device did not crush or crush cardboard box such a tiny size.

The presence of a control panel for the units allows users to control the work process while standing next to the equipment near the load, but only purchased units assembled in production have such advantages.

You are unlikely to be able to make such a device yourself. But you can try to build something similar. Of course, a mini crane assembled by yourself will not be very functional, but it will be able to lift loads of a certain mass to a specified height.

Simple mini-faucet with your own hands

If you make a mini crane with your own hands, it will be able to lift loads weighing up to 250 kg. This will greatly simplify the construction process on site. He can handle lifting logs, concrete mortar, roofing materials. With it, you can do construction yourself without involving a large number of workers.

The main thing when making a mini crane: prepare a drawing, necessary tools and details. The weight of this structure can reach 300 kg. It depends on what materials you will use during assembly. Despite its impressive weight, the mini crane will be distinguished by its compact size and high performance.

Assembling a mini crane with your own hands consists of the following steps:

Using a gearbox, a cargo winch is attached to a worm base.
Construction supports are the basis for screw outrigger systems.
In addition to the basic structure, drums for winches will be required to assemble the unit. Making them on your own is quite problematic. Therefore, it is recommended to purchase ready-made products.
Rotors from an electric motor can be used as a basis.

Attention: at self-assembly mini crane, special attention must be paid to the ratio of the sizes of the elements and the dimensions of the future device.

To make the device convenient to use, its platform can be equipped with wheels. This is where the old transport cart comes to the rescue.

Features of mini cranes assembled by yourself include:

The optimal boom height is 5 meters. To make it yourself, you will need to use a pipe with a diameter of 8 cm.
A profile of 2 corners is mounted on the base and a rotating mechanism is created to rotate the boom. An automobile hub from a truck is suitable as a turning mechanism.
To build a counterweight, you don’t need any special materials. Ordinary bricks can serve as them.

Types of manual taps

All construction cranes are classified into:

self-propelled;
stationary;
tower;
special purpose.

This equipment is equipped with a boom extension mechanism, a cargo trolley, and a rotating support.

By type of movement they are divided into:

stationary;
adjustable;
self-elevating;
mobile.

According to the type of control, these devices are electrically driven and manual (mechanical).

Lift

Modern lifts are divided by type into:

Foot. They are capable of lifting heavy loads weighing up to 2 tons to a height of 8 meters.
Telescopic. Their advantages include: light weight and compactness. These devices are capable of lifting loads to a working height of up to 150 kg.

They, in turn, are divided into:

self-propelled;
non-self-propelled.

When choosing a lift, it is worth considering several factors: their dimensions, load capacity, scope of application.

To make a lift yourself, prepare materials and a preliminary drawing. To build it we will need:

a winch, which can be made from a drum and a cable;
pipes;
electric drive

The advantages of construction hoists include:

maneuverability;
high load capacity;
safety;
ease of use.

Scissor crane

The scissor crane is a simple and easy-to-use design. Due to their versatility and functionality, these devices are used for installation and construction work Oh. They can also often be found in supermarkets and warehouses.

A scissor crane lifts tons of loads every day. This technique, in addition to construction industry, is regularly used in the maintenance of advertising billboards, facade signs, and elevators.

Their main advantages include:

performance;
high load capacity;
compact dimensions when folded;
wide range of applications;
maneuverability.

Their advantages also include autonomy - they can operate on batteries. In addition, cranes can be equipped different types drives:

electrohydraulic;
diesel;
electrical;
hydraulic.

Most often, models with electric drives are used in construction. They are affordable, environmentally friendly and easy to use.

There are a large number of variations of devices of this type, but almost all of them consist of:

lifting device,
mobile platform;
equal-speed drive wheels.

To build a scissor crane yourself, you will need to make the base and platform of the apparatus from a channel. To make scissors you will need:

two-section distributor;
bushings;
pump;
hydraulic cylinder;
I-beams.

A homemade scissor crane is capable of lifting loads weighing up to half a ton. This device is installed on the UAZ, and after operation it is removed. The basis of the structure will be a thick square bolted to the frame, and the retractable pores will be held on the car bumper.

Crane Pioneer

The Pioneer type lift has excellent technical characteristics. It is lightweight and distinguished by maneuverability and mobility. The advantages of this device include the ability to quickly and easily assemble and disassemble.

To deliver the device to the construction site, it can be disassembled and folded into a simple gazelle. After work, it can also be easily disassembled and transported back. The crane can be installed anywhere: on the ground, in a pit, on a roof, on building floors.

This special equipment is produced by different companies in three main modifications of cranes, lifting capacity, and booms.

If necessary, you can make a Pioneer crane yourself, having with you the necessary Consumables, tools, a well-written drawing and free time.

As for the scope of application of the Pioneer, it can be used to move various objects in any weather conditions. It is capable of delivering cargo to any floor or building structure. With its help you can deliver: tools, equipment, building materials and the like.

Quite often this device is used when installing roofs. With it you can quickly lift various loads, machines, metal constructions, materials.

Advantages of the Pioneer crane

The main advantages of the Pioneer crane include:

ease of use - thanks to a simple and reliable design;
the ability to assemble and disassemble the device within half an hour;
mobility, allowing the unit to be used even at distant sites;
low energy consumption.

Important: The Pioneer crane is capable of rotating the boom 360 degrees.

But this unit also has its drawbacks:

it is capable of lifting a weight of no more than 1 ton;
if you hang a flexible load on it, it is not always convenient and safe.

Do-it-yourself Pioneer crane

The Pioneer crane has a simple design. It consists of the following elements:

Main support frame. It can be dismountable, bolted or standing on wheels. The second rotating frame is attached to it;
Safety guy ropes, cargo ropes, electric drive;
Swivel boom. It can be dismountable or bolted;
End stop mechanism. It is located at the end of the boom;
A limit switch located on the mechanism responsible for lifting the load.

So, if you started construction on personal plot, but you don’t have the desire or financial means to hire special equipment, try assembling the crane yourself. With it, you don't have to lift heavy loads yourself.

Attention: The Pioneer construction crane is a collapsible structure designed to lift loads. It can be used when digging a foundation pit for a house, installing a roof, or constructing walls at high altitudes.

The basis of the mechanism is a supporting running frame, which is installed either permanently or on a chassis. The part of the crane that rotates is installed on the frame. You can rotate the boom manually or electric.

The load of this device is lifted using a winch, and stability is achieved thanks to a counterweight and turnbuckles (steel cable guys).

Materials and tools

To make the device we need following materials, which can be found in the garage or in a specialty store:

rectangular pipe;
I-beam;
telescopic unit for I-beam;
small diameter cables;
channel;
electric motor;
winch.

Tools you will need:

keys;
hammer;
Screwdriver Set.

Design diagram

To make a Pioneer faucet with your own hands, you need to make competent scheme. It should strictly indicate: materials of manufacture, dimensions of each individual element, methods of fastening parts.

When creating a diagram of a future design, it is worth carefully calculating everything. If you don’t quite understand this, it’s better to invite a specialist. Having a well-designed diagram in your hands, you can independently manufacture and assemble the device in the shortest possible time.

Assembly Features

As for the assembly of the product:

The crane frame is assembled from a corner 63x63x5 mm.
For a 5-meter boom, a pipe with a diameter of 5–8 cm is required.
To strengthen the structure, you will need 2 corners, measuring 30x30x3 mm.

The carrying capacity of such a device will be 150 kg. If the ropes are strengthened, it will be possible to lift heavier loads.

Attention: Making an electric faucet at home is quite difficult. It will be more expensive and take longer.

When choosing an I-beam, you should make sure that it fits freely into the pipe. It will be installed on sliding guides, resulting in a telescopic unit.

In order for a homemade crane to function well, it will need to be equipped with small diameter cables. They are best purchased at a specialty store. For welding supporting structure and a rotating frame, it is necessary to use a channel.

Thanks to it, the crane will be well fixed to the surface. For safe operation For the device, it is recommended to weld the platform in the form of a rectangle.

To start the lifting process, you will need to purchase an electric motor and connect it to a winch from the UAZ.

Attention: If you want the electric motor to start electrically, invite a specialized technician. Despite the fact that this procedure is not particularly complicated, for safety reasons it is better to use the services of a professional.

That's the whole process of assembling a Pioneer crane with your own hands.

Specifications

Manufacturing and assembly construction crane Pioneer has mass positive points. Its installation on construction site will help you save on the number of builders. With it you can lift roofing materials, timber, working tools and equipment to the required height.

After assembly homemade device You can see its technical characteristics:

The load capacity of the device can vary between 0.5–1 ton. It all depends on the materials used during assembly.
The height of the crane will be 4 meters.
The platform can rotate 360 degrees.

In conclusion, it is worth noting that when starting construction on a personal plot, in order to save money, try to assemble special equipment with your own hands. Of course, you will spend your free time on such manipulations, but you can save a lot. Even big ones construction companies They don’t always buy special equipment. They usually resort to renting units.

Light jib cranes with a lifting capacity of up to 1 ton are indispensable when carrying out various electrical, installation and construction works. Thanks to their design, it is possible to install devices in various openings buildings or on floors, as well as their movement for convenient use. They are easy to assemble and install, and if necessary, they can be quickly disassembled into their component elements and moved to a suitable location.

The use of such structures is rational in the absence of the possibility of operating other types of hydraulic and hydraulic machines. There are many types of cranes with different design. They are divided into stationary and mobile. The boom devices are equipped with one electric drive mechanism for moving the load. The crane operates by manual control.

Construction mini crane

You can independently create a variety of tools and devices that are so necessary for construction and other types of work. Despite the fact that a self-made mini-crane is characterized by a limited transferable load weight (no more than 250 kg), such a design will simplify the implementation of most construction work.

The main task is to select all the tools and parts necessary for creation and subsequent operation. The weight of the prefabricated device can reach up to 300 kg, depending on the materials used. At the same time, it has compact dimensions and the ability to move without preliminary disassembly using a car.

do it yourself: assembly

Using a worm-based gearbox, a cargo winch is formed. It can also provide the creation of a manual drive that simplifies the assembly of the boom winch. The basis for the screw extensions are construction supports. All the elements presented above form the basis of the design. In addition, drums for winches are needed. It is worth noting that they self-production not everyone can do it, since the process is complex and labor-intensive, as well as the need for specialized equipment and experience in carrying out such work.

The way out of the situation is rotors from an electric motor, which can be used as a basis and significantly simplify the task. Special attention should be given to the correspondence of the sizes of the elements used and the future device. To do this, additional measurements are taken using a ruler.

Additional items

To simplify movement, the platform is equipped with wheels. Elements from the conveyor cart may be useful. When creating the structure, you should not forget about this addition, since it is thanks to it that the simplest crane, assembled with your own hands, moves. To do this, you only need to remove the external support elements, which does not cause any particular difficulties and is done in a short time. It is important to observe safety precautions, in particular the boom must be installed on zero level to prevent loss of balance and fall of the crane.

Peculiarities

The optimal boom height is 5 meters. For its manufacture, a pipe with a diameter of about 8 cm is used. A profile of two corners is mounted into the base. You also need to create a rotating mechanism to rotate and lift the boom; a car hub from any truck will do for this. vehicle. Not needed for counterweight special materials, since for them you can take standard bricks. You can create a crane with your own hands using both caterpillar tracks and a frame. The last element can be taken from an unused machine.

It is worth noting that there is no need for a brake for the turning mechanism and winch, since it is not needed during the operation of the crane, and the finished device will operate at low speed.

Advantages of the design

Suitable for forming an external support structure and common ground. For the latter, according to experts, it will be optimal use channel by 200. The length of the thrust screws should be within 50 cm, due to which a do-it-yourself crane can be mounted on any surface, including those with a large number of irregularities. Thus, there is no need to prepare the site on which the building is being built.

Difficulties sometimes arise with wheels, since loose soil they may not scroll well and burrow into it. Therefore, it is advisable to carry out work on hard ground. After completion of construction, the structure is disassembled into its component elements for storage.

What can be done for the garage

At self-repair cars often need to remove the engine, so many car owners are wondering how to make a crane with their own hands. The most simple option is a lift, the creation of which requires a hand winch, racks on triangular supports with wheels and a transverse pipe.

At the top of the racks, fasteners for the pipe are fixed by welding. It is welded to the vertical post and the rollers are mounted on the beam; subsequently they are used to move the cable. In this case, it is not necessary to purchase a winch, as you can do this design on one's own.

Such a device will not clutter up the space, it can be disassembled, and the cross beam and supports separately will not take up much space. The crane, created with your own hands for a garage, is capable of lifting and moving a load weighing no more than 800 kg. Its main advantage is that there is no need to purchase expensive materials.

Lift

As noted earlier, you can make a winch yourself. To do this, you will need a drum equipped with a cable; it must be fixed to a structure made of pipes with square section. A small sprocket with a chain drive is installed on the electric drive, and a large one is installed on the edge of the drum. To create a manual winch, a shaft equipped with a drum is supplemented with a handle.

To replace and repair most parts in a car, a platform or pit is required; if they are not available, you can use a lift. Despite the existing risks when working with such a device, its creation is justified by economic benefits and practical benefits.

An overhead trolley crane, assembled with a winch yourself, is the simplest option; the machine is installed on platforms after being raised to the desired height. There is also a scissor design, which is characterized by the absence of the possibility of cable breakage, which the previous option cannot guarantee.

Scissor crane

The base and platform of the scissor lift are made of channels. Two-piece distributor, pump, bushings, and are required for shears.

A self-made UAZ crane is capable of lifting loads weighing more than 500 kg. It can also be removed upon completion of work. The main purpose of the device is to fix retractable supports. The base of the structure is made of a thick-walled square, secured to the frame with several bolts. The retractable pores stay on the bumper and raise the rear of the car.

Crane “Pioneer”

The mechanism makes it possible to simplify the implementation of many repair and construction works, as well as to ensure the implementation of actions that cannot be performed without additional lifting devices. The design is suitable for cargo of various volumes and sizes, and it can be installed on the floors of houses under construction, in pits and on the roof.

Among the main constituent elements It is worth noting the rotating and supporting frames, the control panel. The device does not cause any difficulties in the process of use and the application of significant physical effort. Management is within the power of every person, even those without relevant experience.

Many owners of private houses and summer cottages. Their spread is due to the fact that each part of the mechanism, regardless of its complexity, can be performed in the desired manner and with the necessary functionality. In addition to moving heavy loads such as monolithic blocks, such cranes enable the delivery of light objects to great heights.

Unfortunately, the creation of hydraulic devices is, as a rule, not possible. But, despite this, the crane (with your own hands), the photo of which is presented below, is easy to operate and has sufficient lifting capacity.

Assembly of the Pioneer crane

Many parts can be found, surprisingly, in a landfill. For homemade mechanism the main components are a rectangular pipe and an I-beam. It is important that the latter fits easily into the pipe. To create a telescopic unit for an I-beam, sliding guides are made. It is worth noting that they must be lubricated special compounds to reduce friction.

For the device to function, cables with a small diameter are also required. They can be purchased at hardware store. A channel is often used to secure the rotating and supporting frames. It also ensures that the device can be firmly mounted on any surface. As a rule, it is the roof of a building under construction. In accordance with safety regulations, the manufacture of a rectangular platform as ballast is required, and it will reduce the likelihood of problems while the crane, assembled with your own hands, is in operation. An electric motor connected to a winch is used to start the lifting process.

The design of a homemade crane will help those who themselves build a residential building, a summer house or a garden house.

A homemade crane will make it easier to install foundations, walls, ceilings and other structural elements.
Using such a jib crane, you can carry a load over a distance of up to 3 m, lift it to a height of up to 2 m and lower it to a depth of 2.5 m. The mechanism should be designed to install structures weighing up to 300 kg.

The crane consists of a horizontal boom beam (the crane trolley moves along it) and vertical support posts, made from steel pipes, to which horizontal beams are attached. The crane is collapsible, which allows you to move it from place to place.
Construction of crane stands.
They are made of pipes with a diameter of 140 mm. Their height can be increased up to 3 m using telescopic incoming pipes. To prevent the posts from sinking into the ground, corners are welded to the base. Welded to the top of the supports horizontal beam- two corners joined together x 65 x 10 mm. A horizontal guide is attached to it from below with four bolts - an I-beam No. 20, having dimensions of 200 x 100 x 5.2 mm, 3000 mm long, along which the crane trolley moves.

The second pair of guide supports consists of two vertical pipes connected at the top and bottom. For greater stability, two inclined supports are welded to them, which in turn connect the racks with a rectangular frame. The latter prevents the crane from tipping over, as it serves as a base for laying sandbags or concrete blocks.

An important feature of a jib crane is its control. Those who will build and operate it need to know: the crane has a lifting and moving device. If necessary, any detail can be lowered below zero mark(in a pit or trench). The entire system of cables and pulleys of the lifting device is driven by an electric motor. The trolley is moved by a hand winch using a cable. One end of it is fixed on the trolley, then the cable goes through a block to the drum, makes five turns and, again passed through the blocks at the base and at the end of the boom, is fixed on the crane trolley.

The hook is lifted by a cable, fixed at one end to the winch and passing successively through the blocks of the base, boom and crane trolley; then the cable goes down, forms a loop on which a block with a hook is suspended, and is secured to the end of the boom through the block of the crane trolley.

The lifting device can also be driven by a conventional manual winch, which will provide the crane with complete autonomy.

Before starting work, you should carefully check the strength of the nodes and supports. Standing under the boom is not allowed - this is the basic safety rule at any construction site.

We hope that there will be farmers and gardeners who will build a crane to make their work easier. Maybe not like that. But similar. The main thing is that he helps in the work.

When building a house from aerated concrete, timber, brick, etc. There is often a need to lift a load. For example, you need to “throw” blocks or wooden beams to the second floor, lift bags of cement or pour an armored belt. Doing this manually, even with the help of assistants, is not so easy - health is more expensive. Hiring a truck crane or manipulator for a small amount of work is expensive. The solution is to use a mini-crane, which, to reduce the cost of construction, is made by hand.

How to make a lift for laying aerated concrete.
What parts and tools are needed to build a mini crane.
How to reduce the costs of building a universal lift.

Lift for laying aerated concrete blocks

Abroad, during the construction of private houses, cranes and various lifts are often used. This way construction goes faster, which means the “box” is cheaper, because It is more profitable to use small-scale mechanization tools than to hire laborers. Our developer relies on himself and often builds a house “with one helmet.” Therefore, the urgent question is how not to physically overstrain yourself when laying a wall from aerated concrete blocks weighing 35-40 kg.

An interesting variant of an unusual homemade “assistant” of the FORUMHOUSE user with the nickname Cross. First, let's show what he took as a basis.

German mini crane with retractable central post

A special feature of the lift is the original folding “arm-boom”, with the help of which the crane, moving on wheels, can reach two opposite walls.

Cross

I am building a house myself and in order to be able to put aerated concrete blocks, built a lift according to the above model. The crane was made completely collapsible, except for the base. Maximum load I didn’t measure it on the hook, but it calmly lifts me (weighing 95 kg).

Technical characteristics of the lift:

width – 2200 mm;
height – 4200 mm;
boom radius – 4200 mm;
load capacity of electric hoist – up to 800 kg;
total weight of the crane with ballast is approximately 650 kg;
lift weight without ballast – about 300 kg;
The maximum lifting height of the masonry block is 3500 mm.

The working height of lifting blocks is adjustable in two ranges. The first is 1750 mm. The second is 3.5 m, for which the structure is raised, sliding upward along the supporting “legs” using a hydraulic jack lined with spacers made of GB blocks.

To make the lift, the user needed:

swivel wheels;
profile pipes for the mast, “legs” and boom with a section of 12x12 cm, 12x6 cm, wall 6 mm;
pipe-jibs – 63x3 mm;
powerful gate hinges;
The boom rotating mechanism is made of ST45 steel and “205” bearings.

During operation, the design was modified. For example, the user laid the cable for the winch in a corrugated pipe and extended the cable for the control panel.

Cross

The design has a number of shortcomings that I would like to correct. For example, I’m thinking about making wireless control, replacing the gate hinges with bearings. Increase the number of “joints” in the boom at the same reach. Instead of a temporary counterweight - bags of sand concrete, pour concrete ballast.

Important nuance: so that the lift can move around the construction site or, for example, along concrete slab second floor ceilings need to be supported workplace clean, because GB fragments and debris interfere with the relocation of the tap.

The design of the unusual lift attracted the interest of portal users.

Konstantin Y. Member of FORUMHOUSE

With such a lift, I think, as they do in Germany, you need to make masonry from blocks larger than standard ones. The length and height are 2-3 times greater than a regular GB. The crane has enough lifting capacity, and the laying speed will increase significantly.

According to Cross, he heard that someone on the portal had already tried to order blocks of 1x0.4x0.6 m format from a gas silicate manufacturer. But it turned out that this was not profitable for the plant, because it is necessary to reconfigure the line for the production of GB, and for the sake of a small volume (to a regular a private house) will not do this.

Vegaroma FORUMHOUSE Member

I'm wondering: is the work on site easier when using a crane? What work can be done with it and what cannot?

Cross

There is no need to install scaffolding when laying GB walls. The lift can be assembled and disassembled. I poured the concrete lintels over the windows the old fashioned way, from buckets, because... The volume is small, and it’s easier to do it with one assistant.

Grand total: The mini-crane turned out to be successful, and with some modifications to its design, the lift can be put into small-scale production.

Mini crane made from scrap metal

Another option lifting mechanism made from metal “lying underfoot” by a portal member with the nickname Peter 1.

According to Peter 1, The reason for building a crane is that the house is getting higher and higher, and the blocks and concrete are getting heavier. Therefore, after revising the “unnecessary things”, the user manufactured a completely dismountable crane with a lifting capacity of 200 kg.

Peter 1

I think my crane can lift more, but I didn’t overload it. The crane can be disassembled into parts weighing 30-60 kg and can be easily transported in a trailer passenger car. I carry an arrow on the trunk. Statically tested a structure weighing 400 kg. I usually lift up to 150 kg. This is quite enough for my construction needs.

At one time, the crane, with a boom reach of 5 m, lifts 10 blocks weighing 15 kg each, or four 15-liter buckets of solution.

The design of the crane is a hodgepodge of what was at hand. Let's list the main details:

swivel unit - truck hub;

Hubs from cars, trucks, and farm equipment are often used to make the swivel assembly in homemade cranes. The main thing is to calculate the loads acting on it and the fasteners.

the boom is made of a pipe with a diameter of 75 mm;

outriggers and base - a rectangular pipe with a section of 8x5 and 8.5x5.5 cm;

the base of the tower is the “200th” channel;

worm gearboxes for boom and cargo winches.

three-phase electric motor with reverse, power 0.9 kW, converted to power from a 220 V network;

The crane turned out to be mobile, and by lowering the boom, it can be moved from place to place, rolling on wheels along compacted soil. Level adjustment is carried out using screw supports.

Metal, gearboxes and rollers were purchased at a recycled metal shop. Only the cable and bearings are new.

The weight of the crane without counterweight is about 250 kg. Cost of construction, taking into account the purchase of consumables - cutting discs for angle grinders, electrodes for welding inverter and paints - 4 thousand rubles.

Crane, + time for turning, + selection of components and fitting of components, I completed it in 3 working days. In the future, after finishing the work, I will completely disassemble it.

Inexpensive mini lift

Practice shows that a real crane is not always needed when building a private house. Often, a developer can get by with “little expense” and make a small lift based on an electrically driven hoist.

My design is simpler than the authors above, but it suits me quite well. I bought a hoist with a load capacity of 300 kg without a block and 600 kg with a block. Tests have shown that the device can lift a load weighing 250-270 kg, then the engine protection is triggered. During the construction season, I used it to lift about 40 pallets of building blocks, 6 meter beam for the Mauerlat, rafters, mortar for masonry and concrete for the reinforced belt.

The lift, again to save money, is made from used pipes, angles and channels.

These are topics that describe in detail how to make a lift for aerated concrete, and provide dozens of options for mini-cranes, from simple to the most complex designs.
