To repair a car yourself, you need a lift. Therefore, an engine lift should be in every garage, but purchase professional equipment expensive. In addition, being large in size, it will take up a lot of space in the garage. If you make a beam crane with your own hands, you can save money.
Tools and materials
The crane beam consists of a guide, a lifting mechanism and end beams. This is a convenient design that can be used not only indoors, but also outdoors. Before you start making it, you need to make calculations and prepare a drawing.
Tools and materials you will need:
- for support rods - several pipes 11 cm in diameter;
- for a cross rod (solid) - a pipe 10 cm in diameter;
- hoist and manual hoist;
- for the rack - a pipe (with a square cross-section) 10x10 cm;
- under the base and for bevels - metal corners 10x10 cm;
- M16 fixing bolts;
- welding machine.
Calculation
The calculation of the 250 cm high crane beam was made for working with passenger cars. The crane is capable of lifting elements weighing up to 800 kg. The width of the structure is 415 cm, and the size of the racks is 120 cm. For larger equipment, the lifting mechanism is equipped with vertical A-shaped racks. To securely fasten the bar to the supports, scarves are used.
Assembly instructions
It will take 2 days to assemble a simple or movable structure. The process of making a crane beam with your own hands:
- The main load that will be moved crane, falls on the counter. To securely fix the structure, you need to make a frame. To do this from metal corners weld the legs under the tap. The corners are welded to the pipe at an angle of 45° on both sides of the pipe.
- To make spacers, 2 triangles are welded to each rack.
- For a mobile structure you will need rollers. They are welded to a horizontal base, positioned on both sides of each rack. To prevent the rollers from breaking and to withstand the weight, use products that are designed for metal containers. Furniture cannot be used.
- A pipe is installed at the top of the structure. It is designed to move the lifting mechanism.
- The roller for moving the cable is mounted on an I-beam. The I-beam is pre-welded at the central point of the pipe.
- To give the frame additional stability, a square-section pipe is welded to the beam element. It is placed on top of the beam so that it protrudes forward by 20 cm on both sides.
- The cross pipe is inserted into a pipe with a square cross-section and drilled on both sides through holes under fastenings. Bolts are used as fasteners. Homemade frame ready for U-shaped tap. The pipe in the form of a crossbar is securely fixed in the upper part of the product, and the entire structure is stably placed on spacers (legs).
- Mechanical lifting is designed to lift parts. It can be manual or automatic. Manual hoist consists of a winch and a cable. The worm winch is mounted on the side of the rack. The movement of the steel cable occurs through rollers.
- The structure can be equipped lifting mechanism, which is used in elevators. This mechanism has strong rollers.
- Connection electric drive the lift will make it easier renovation work. An engine with a power of 300 to 500 W is suitable for installation. It is mounted on the base of the structure.
Light jib cranes with a lifting capacity of up to 1 ton are indispensable when carrying out various electrical, installation and construction work. Thanks to their design, it is possible to install devices in various openings of a building or on ceilings, as well as to move them 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. He can also ensure the creation manual drive, which 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 not everyone can make them independently, since the process is complex and labor-intensive, as well as the need for specialized equipment and experience in carrying out similar 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 follow safety precautions, in particular the boom must be set to zero level to prevent loss of balance and the crane falling.
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. The counterweight does not require special materials, since they can be taken 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 rotary mechanism and winches, since it is not needed during the operation of the crane, but the work finished device will be done 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 to use a 200 channel. The length of the thrust screws should be within 50 cm, due to which the crane can be mounted with your own hands on any surface, including big amount unevenness. Thus, there is no need to prepare the site on which the building is being built.
Difficulties sometimes arise with the wheels, since on loose soil they can spin poorly and dig 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 will require 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 hydraulic devices, as a rule, is 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.
Sometimes when working under the hoods of cars, there is a need for additional mechanisms that can help pull out or hang the engine, while leaving enough space in the hole under the car to access all the parts of the car. Ideally, such a device that assists in car repairs should:
- do not clutter the space in the garage;
- understand the constituent elements;
- be independent of the ceiling fixed eyebolt.
This is exactly the type of mechanism that a self-made crane beam is.

Construction of a crane beam for a garage with your own hands
1. As a result of performing all the steps described below, a crane beam will be built, which will look like this when assembled:
2. When disassembled, this garage tool will look like this:
The height of such a crane beam will be 250 cm, width - 415 cm. The base of the racks will have a size of 120 cm. All sizes are designed to work with passenger cars. If a beam crane is needed to work with more massive vehicles, then it is better to strengthen the structure by making A-shaped vertical posts and additionally using gussets for the boom supports; the material used will have to have big sizes than those given.
3. We will use the following materials for the crane beam:
- a pipe with a diameter of 10 cm, which will serve as a transverse seamless rod;
- pipes with a diameter of 11 cm, which will act as rod supports;
- M:16 bolts for attaching to the rod supports;
- pipe square profile 10x10 cm, used as a stand;
- corner 10x10 cm for the base and bevels;
- rollers for the cable (you can use rollers from the elevator door drive).
4. The rollers are attached to a 5 cm strip, which is welded overlapping to the junction of the rod with the supports.
5. To ensure the mobility of the tool, rollers taken from containers used in warehouses are welded to the racks.
When folded out, this item takes up very little garage space.
6. The lifting mechanism is constructed from a manual worm winch with a capacity of 800 kg, having steel rope, by welding it to a vertical post.
For those who repair cars, a jack alone is not enough. To pull the engine out you need a crane. Of course, this option http://sdm-group.com.ua/catalog/mostoviekrani is not needed in the garage, but a smaller and modernized version, and also collapsible, will be useful to many car enthusiasts and not only.
And this is not an industrial product. This beam crane was made by some craftsmen in their garage with their own hands.
This photo shows the main dimensions 
The main materials used were:
For a solid-drawn cross rod with a diameter of 100mm and a length of 4150mm
For rod supports, a pipe with a diameter of 110 mm (cut a piece 1200 mm long into two identical parts
Mounting bolts support for rod M:16
The stands are made of square pipes 100x100mm length 2350 mm
The bevels and base are a 100x100mm corner
The rollers installed on the crane beam are parts of the elevator door drive. They are attached to a 50mm strip of metal and overlap welded to the rod and to one of the rod supports.
The size of this beam crane was not chosen by chance. This model is designed to work with passenger cars.
The mobility of the structure is ensured by ordinary rollers from a storage container welded to the vertical posts.
The disassembled design of our beam crane takes up very little space.
The lifting mechanism is a conventional worm-type hand winch welded to a vertical post. Its carrying capacity is somewhere around 800kg. The drive is a steel cable. . 
You can also adapt an electric winch if you wish, but there is no particular need for this.
The above construction is not a dogma. This option was made for specific tasks and the material available at hand. Any engine passenger car It pulls out easily and calmly lifts the Volga by the hood. On sale, if you search, you can find a similar crane industrial production, but the price will be decent. The idea has been proposed to you, but whether you want to implement it is up to you.
Any user of the site will agree with the statement that one of the most necessary things during construction is a crane. The steel hero becomes an indispensable assistant when there is a need to lift a large load.
A lifting mechanism is usually associated with a huge structure tens of meters high. However, in private house-building, when compact mechanisms for construction come to the fore, one needs an option with a boom length not exceeding 5-7 meters.
But renting it is not a cheap pleasure, especially if the construction lasts for more than one month.
In this case, there is only one way out - roll up your sleeves and build a homemade mini-crane with your own hands. And our forum members will help you with this!
How to make a homemade faucet
Saving on your own health and trying manually lift an unbearable load, especially if the construction of the house is carried out independently and without the involvement of hired labor work force, they don’t lead to any good. We have already told our readers. Now we are making a crane with our own hands to build a house called “ mini-pioneer."
"Pioneer" is a mobile collapsible design, with the help of which the load is lifted to a given height. So homemade The crane can be used when digging foundations and construction and installation work on building houses.
The basis of the mechanism is a supporting running frame, installed permanently or on a mobile chassis. The rotating part of the crane is mounted on the frame. The boom can be rotated manually or electrically. The crane design itself is made on a modular basis and can be disassembled into several parts for the convenience of moving the mechanism from one construction site to another.
The stability of the structure is ensured thanks to a counterweight and steel cable guys (turnbuckles), and the load is lifted using a winch and a block.
The experience of our forum member, who decided to build a mini “Pioneer” on his own, is interesting. He needed this construction mechanism to build a private house from timber.
Voldemort:
“I am almost single-handedly building a house from six-meter timber. It is impossible to lift and carry it alone. That is why I decided to assemble a mechanism in order to take the timber from the stack, place it at the sawing site and lift it to the plinth.
As the height of the building increases, our forum member plans to place a crane on the floor beams of the house.
A forum member assembled the frame from a corner 63x63x5 mm. The 5-meter-long boom was made from a pipe with a diameter of 50 mm. To strengthen the structure, two corners 30x30x3 mm were used. Also included in the plans Voldemora includes further extension of the boom by another 2 meters.
Voldemort:
– The lifting capacity of the mechanism is approximately 150 kg, but the design can lift more weight, and in order to achieve this, it is necessary to increase the multiplicity of pulleys.
Translated from Greek, Polyspaston means “tensioned by several ropes.” They call it a chain hoist construction device for lifting loads. It consists of several blocks connected to each other by a rope or cable that goes around the blocks in a circle. A pulley block allows you to lift a load with less effort than the weight of the load.
The simplest pulley allows you to get a three-fourfold gain in strength; we should not forget that friction losses are inevitable in this system. Even in best models blocks they reach 10%. And the more you gain in strength, the more the distance over which the equipment can move the load decreases.
Voldemort:
– It took me a week to make all the components and mechanisms. I spent another two days assembling and fine-tuning the mechanism. The swing drive and the boom lift drive are a six-fold manual pulley. The lifting drive is also a manual double chain hoist.
Voldemort notes that it would be much more convenient to control a mechanism with electric drives - to lift the load from a remote control on a long cord, as is done in industrial models. But in this case, the complexity of manufacturing all the mechanisms increases significantly, which will lead to an increase in the cost of the design and an increase in the time for manufacturing the crane.
The details of the device's manufacture are interesting.
Voldemort:
– As a turntable, I took two faceplates that I found at work. Basically, I assembled the mechanism from what was at hand. Instead of an axle, I welded a 30 mm bolt. I did not take a bolt made of high-strength steel, because such ones weld worse, do not stretch or bend, and immediately burst if their strength limit is exceeded.
All components of the device are lubricated with lithol.
To reduce the weight of the counterweight, the length of the support legs is 2 meters. At self-production When calculating the components of such a device, one point should be taken into account. The fact is that with a radius of the rotating faceplate of 200 mm and a distance of 2 meters to a counterweight weighing 100 kg, a tensile load of 1 ton acts on the central bolt. And this does not take into account the weight of the boom and the load being lifted!
It is also important to check the device for stability.
Voldemort:
– To begin with, let’s imagine that our crane is a single beam that rests on one support, and this support should be the shortest distance from the axis of rotation. Three forces act on the beam: the weight of the load, the weight of the counterweight and the mass of the mechanism. In order not to take into account the mass of the boom, I underestimated the weight of the crane by 50 kg. The calculation is approximate and simple, but it is better with it than without it at all.
Boom lift drum Voldemort Made from a tube with a diameter of 100 mm.
Voldemort:
– There is a nuance here - the drum cannot be placed close to the blocks. It needs to be shifted slightly along the axis towards the first block so that the second layer of cable is wound evenly.
A forum member made the blocks from three washers: two large and one small. All blocks are without bearings. It is important to ensure that the blocks bend well with the rope. That is, either the rope must be flexible, or the blocks must be of large diameter. Otherwise, when the boom is raised without load, the cables may fly out of the blocks.
Voldemort:
– My rope has a diameter of 12 mm, but it is very thick - there was simply no other way. If I extend the boom, I will install a more flexible cable with a diameter of 5 mm, because its working load is 150 kg, and its breaking load is 850 kg.
When designing block systems, it is important to understand how the chain hoist works and is calculated. Let's look at this using the example of a mini-pioneer.
Voldemort:
– The principle of operation of a pulley block is similar to the operation of a gearbox - you gain in strength, but lose in the length of the rope and, consequently, the speed of lifting the load.
In the gearbox main characteristic- this is the gear ratio, and in a chain hoist - the multiplicity, i.e. the ratio of all rope branches to those running off the drum. If we have 6 sections of rope, it means the chain hoist is six-fold.
This means that the pulling load on the drum will be 6 times less than the weight of the load, and the rope itself, if it is designed for 100 kg, then rolled 6 times, will lift 600 kg.
Do-it-yourself construction mini-cranes
The design turned out to be so successful that many of our users decided to repeat it and even give the crane mobility by placing it on a Gazelle.
Forum member with nickname plumag proposes using a similar mechanism with a higher load capacity and equipped with electric drives to install concrete pillars. And in order to be able to transport such an individual crane on public roads, make the structure collapsible and partially and completely install it in the body at the site of the intended work. This will allow short time recoup all costs associated with the manufacture of the device.
At FORUMHOUSE you can learn everything about self-help, and also get acquainted with the mini-pioneer. The portal discusses everything you need to know to make a faucet, from a concrete mixer to a pipe bender. Topics from forum members about making useful household items that will help you build.
