How to make a self-leveling crane?

Without boom light cranes with a carrying capacity within 1 ton, you can not do with various electrical, installation and construction works. Due to their design, it is possible to install devices in various structures of the building or on the floors, and also to move them for convenient use. They are easy to assemble and install, and if necessary they can be quickly disassembled into component elements and moved to a suitable place.

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

Construction mini-crane

Independently, you can create a variety of tools and instruments, so necessary for construction and other types of work. Despite the fact that the mini-crane, made by hand, is characterized by a limited carrying weight (no more than 250 kg), this design will simplify the implementation of most of the construction work.

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

Self-erecting crane : assembly

With the aid of a reducer on a worm-like basis, a cargo winch is formed. It can also provide the creation of a manual drive, simplifying the assembly of the boom winch. The basis for the screw extensions are the building supports. All the elements presented above form the basis of the design. In addition, we need drums for winches. It should be noted that not everyone is able to produce them independently, because the process is complicated and laborious, and also the need for specialized equipment and experience in carrying out such work.

The way out of the situation is the rotors from the electric motor, which can be used as the basis, and greatly simplify the task. Particular attention should be given to the correspondence between the dimensions of the elements used and the future device. For this, additional measurements are made using a ruler.

Additional Items

For ease of movement, the platform is equipped with wheels. Items from the conveyor cart can be useful. In the course of creating a design, do not forget about this addition, since it is thanks to him that the simplest crane, assembled with its own hands, moves. For this it is only necessary to remove the outriggers, which does not cause any special difficulties and is produced in a short time. It is important to observe safety techniques, in particular, the boom should be set to zero level to prevent loss of balance and crane drop.

Features

The optimum boom height is 5 meters. For its manufacture a pipe with a diameter of about 8 cm is used. The profile of two corners is mounted in the base. It is also necessary to create a swivel mechanism for turning and lifting the boom, for this purpose an automotive hub from any truck is suitable. For the counterweight, special materials are not needed, as for them it is possible to take standard bricks. Create a self-leveling crane is possible on the basis of caterpillar tracts, and the bed. The last element can be taken from an unused machine.

It is worth noting that there is no need for a brake for the swivel mechanism and winch, as it is not needed during the operation of the crane, and the work of the finished device will be performed at a low speed.

Advantages of construction

Rectangular pipe is suitable for the formation of an outrigger support structure and a common base. For the latter, according to experts, it will be optimal to use a channel for 200. The length of the thrust screws should be within 50 cm, due to which the hoisting crane can be mounted on any surface, including with a lot of unevenness. Thus, there is no need to prepare the site on which the building is built.

Difficulties sometimes arise with wheels, as on loose soil they can badly scroll and burrow into it. Therefore, the work is preferably done on hard ground. After the construction is completed, the structure is disassembled into components for storage.

What can I do for a garage?

When self-repairing cars often there is a need to remove the engine, so many car owners are wondering how to make a self-leveling crane. The simplest version is a lift, which requires a hand winch, stands on triangular supports with wheels and a cross pipe.

On the upper part of the pillars by welding welded fastenings for the pipe. A hand winch is welded to the vertical stand , and the rollers are mounted on a beam, later they are used to move the cable. In this case, it is not necessary to purchase a winch, since it is possible to make this design independently.

Such a device will not clutter the space, it can be disassembled, and separately the transverse beam and supports will not take up much space. The crane, with its own hands for the garage created, is capable of lifting and moving a load of not more than 800 kg. Its main advantage is the lack of the need to purchase expensive materials.

Lift

As it was noted earlier, the winch can be made independently. To do this, you need a drum equipped with a cable, it needs to be fixed to a structure of pipes having a square cross-section. A small asterisk with a chain transmission is installed on the electric drive, and a large one is mounted on the edge of the drum. To create a hand winch, the shaft equipped with a drum is supplemented with a handle.

To replace and repair most parts in the car requires an overpass or a pit, in the absence of them you can use the lift. Despite the existing risks when working with such a device, its creation is justified by economic benefits and practical use.

A bridge crane-trolley, assembled with its own hands and a winch, is the simplest version of the lift for a car, while the machine is mounted on the platform after lifting to the desired height. There is also a scissor-type construction, which is distinguished by the absence of the possibility of cable breakage, which the previous version can not guarantee.

Scissor Crane

The base and the platform of the scissor lift are made of channels. Two-piece distributor, pump, bushings, hydraulic cylinder and I-beams are necessary for scissors.

The crane on the UAZ, made with its own hands, is capable of lifting loads weighing more than 500 kg. Also after the completion of the work it can be removed. The main purpose of the device is to fix the telescopic supports. The basis of the design is made of a thick wall, fixed on the frame with a few bolts. Retractable pores are held on the bumper and lift the rear of the car.

Crane "Pioneer"

The mechanism allows to simplify the implementation of many repair and construction works, as well as to ensure that actions that can not be performed without additional lifting devices. The design is suitable for cargo with a different volume and size, while it can be installed on the ceilings of erected houses, in foundation pits and on the roof.

Among the main components are a turning and support frame, electric winch, control panel. The device does not cause difficulties in the process of use and application of considerable physical effort. Management is within the power of every person, even without relevant experience.

Many owners of private houses and country plots are engaged in the construction of lifting structures. Their distribution is caused by the fact that each part of the mechanism, regardless of its complexity, can be performed in the desired way and with the necessary functionality. In addition to moving heavy loads, such as monolithic blocks, similar cranes ensure the delivery of light objects to a high altitude.

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

Assembly of the crane "Pioneer"

Many details can be found, surprisingly, in a landfill. For the homemade mechanism, the main components are a rectangular tube and an I-beam. It is important that the latter is easily placed in the pipe. To create a telescopic knot for the I-beam, sliding guides are made. It should be noted that they must be lubricated with special compounds to reduce the degree of friction.

To operate the device, cables with a small diameter are also necessary. They can be purchased at a construction store. A channel is often used to fasten the rotating and supporting frame. It also provides a tight installation of the device on any surface. As a rule, it is the roof of the building under construction. In accordance with the safety rules, it is required to make a rectangular area as a ballast, while reducing the probability of problems while the crane is being operated, assembled with its own hands. An electric motor connected to the winch is used to start the lifting process.
