Without jib light cranes with a lifting capacity of 1 tonne can not do with the implementation of various electrical, installation and construction works. Thanks to their design, it is possible to install devices in various openings of a building 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 components 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 geological and mechanical equipment. There are many types of cranes with various designs. They are divided into stationary and mobile. Boom devices are equipped with one electric drive mechanism for moving cargo. The crane is operated by manual control.
Mini construction crane
You can independently create a variety of tools and devices, so necessary in construction and other types of work. Despite the fact that the do-it-yourself mini-crane is characterized by a limited carry mass (not 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 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 prior analysis using a car.
DIY Crane : Assembly
With the help of a worm-based gearbox, a cargo winch is formed. It can also provide the creation of a manual drive that simplifies the assembly of a boom winch. The basis for the screw remote parts are the construction supports. All the elements presented above form the basis of the design. In addition, we need drums for winches. It is worth noting that their independent production is not for everyone, since the process is complex and time-consuming, as well as the need for specialized equipment and experience in carrying out such work.
The way out of the situation are rotors from an electric motor, which can be used as a basis, and significantly simplify the task. Particular attention should be paid to the conformity of the dimensions of the elements used and the future device. For this, additional measurements are made using the ruler.
To facilitate movement, the platform is equipped with wheels. Elements from the conveyor cart may come in handy. In the process of creating the structure, do not forget about this addition, since it is thanks to it that the simplest crane assembled with its own hands moves. To do this, you only need to remove the remote support elements, which does not cause much difficulty and is produced in a short time. It is important to observe safety precautions, in particular, the boom should be set to zero to prevent loss of balance and the crane falling.
The optimum boom height is 5 meters. A pipe with a diameter of about 8 cm is used for its manufacture. A profile from two corners is mounted in the base. You also need to create a rotary mechanism for turning and lifting the boom, for this a car hub from any freight vehicle is suitable. Special materials are not needed for the counterweight, since standard bricks can be used for them. You can create a crane with your own hands on the basis of caterpillar tracks, and the bed. The last item can be taken from an unused machine.
It is worth noting that there is no need for a brake for the rotary mechanism and winch, since it is not needed during the operation of the crane, and the finished device will be operated at low speed.
A rectangular pipe is suitable for forming an external structure of a support and a common base. For the latter, according to experts, the use of a channel for 200 will become optimal. The length of the stop screws should be within 50 cm, due to which the crane can be mounted on its own with any surface, including 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 on loose soil they can scroll poorly and dig into it. Therefore, work is preferably on solid ground. After completion of construction, the structure is disassembled into the constituent elements for storage.
What can be done for the garage
With self-repairing the car, it is often necessary to remove the engine, so many car owners are wondering how to make a crane with their own hands. The easiest option is a lift, which will require a hand winch, racks on triangular supports with wheels and a transverse pipe.
On the upper part of the struts, welding fastenings for the pipe are fixed. A manual winch is welded to a vertical stand , and the rollers are mounted on a beam, subsequently they are used to move the cable. It is not necessary to purchase a winch, since you can make this design yourself.
Such a device will not clutter up the space, it can be disassembled, and separately the transverse beam and supports will not take up much space. A self-made crane for the garage is capable of lifting and moving loads weighing no more than 800 kg. Its main advantage is the lack of the need to purchase expensive materials.
As noted earlier, a winch can be made independently. To do this, you need a drum equipped with a cable, it must be fixed on the construction of pipes having a square section. A small chain sprocket is mounted on an electric drive, and a large sprocket on the edge of the drum. To create a manual winch, a shaft equipped with a drum is complemented by a handle.
To replace and repair most of the parts in the car, an overpass or pit is required; in their absence, you can use the elevator. Despite the risks involved in working with such a device, its creation is justified by economic benefits and practical benefits.
The do-it-yourself overhead crane-truck crane is the simplest version of a hoist for a car, and the machine is mounted on platforms after lifting to the desired height. There is also a scissor structure, which differs in the absence of the possibility of cable breakage, which the previous version cannot guarantee.
The base and platform of the scissor lift are made of channels. A two-piece distributor, pump, bushings, hydraulic cylinder and I-beams are required for scissors.
A do-it-yourself UAZ crane is capable of lifting loads weighing more than 500 kg. Also, upon completion of work, it can be removed. The main purpose of the device is to fix the sliding supports. The basis of the design is made of a thick-walled square, fixed to the frame with a few bolts. Retractable pores hold onto the bumper and lift the rear of the car.
The mechanism allows to simplify the implementation of many repair and construction works, as well as to ensure that actions that cannot be performed without additional lifting devices. The design is suitable for cargo with various volumes and sizes, while it can be installed on the floors of houses being built, in pits and on the roof.
Among the main components it is worth noting the swivel and support frames, electric winch, control panel. The device does not cause difficulties in the process of using and applying significant physical effort. Management is within the power of every person who does not even have the appropriate experience.
Many owners of private houses and summer cottages are engaged in the creation of lifting structures. Their distribution is due to 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, such cranes provide the delivery of light objects to great heights.
Unfortunately, the creation of hydraulic devices, as a rule, is not possible. But, despite this, the crane (with its own hands), the photo of which is presented below, is notable for its ease of operation and sufficient carrying capacity.
Assembly of the Pioneer crane
Surprisingly, many details can be found in a landfill. For a home-made mechanism, the main components are a rectangular pipe and an I-beam. It is important that the latter fits easily in the pipe. To create a telescopic assembly for an I-beam, sliding guides are made. It should be noted that they must be lubricated with special compounds to reduce the degree of friction.
For the functioning of the device also need cables with a small diameter. They can be purchased at a hardware store. A channel is often used to secure the swing and support frames. It also provides tight installation of the device on any surface. As a rule, it acts as the roof of a building under construction. In accordance with safety rules, the manufacture of a rectangular platform as a ballast is required, while it will reduce the likelihood of problems while the self-assembled crane is in operation. An electric motor connected to the winch is used to start the lifting process.
