Build Your Own Crane
This construction has a lifting capacity of approximately 200 kg. The crane is a fully assembled structure that weighs between 200 and 300 kg, so assembling such a crane by yourself should not pose any difficulties. Furthermore, it is very convenient for transportation as it easily fits into a pickup truck.
We use a worm gear reducer with an electric drive of 600 watts, and for the hoist, you can make it with a manual drive – a reducer.
You can use construction supports with screw supports as the basis for the outriggers. To make the winch drums, take rotors from electric motors.
For mobility, equip the crane with wheels, making it quite mobile. However, to move the crane, you need to lower the boom to the zero level; otherwise, the crane may tip over due to the disturbed balance.
The crane has a five-meter boom made from a 7.5 cm diameter tube and a square profile made from two angles.
The crane also has a gantry for lifting the boom and a rotating mechanism, the basis of which is a hub from a commercial vehicle.
For the counterweight, you can use concrete blocks or a metal counterweight.
- The swivel mechanism does not have a brake since the crane is not designed for high speeds, and therefore, the inertial forces are too low.
- The outrigger and base are made of rectangular tubes with dimensions of 85 by 50 and 85 by 55.
- To make the tower base, a 200-shelf is used.
- The hook clamp is equipped with a powerful bearing, meaning that the hook’s rotation does not depend on the pulley block.
The length of the support screws is 40 cm. This allows the crane to be installed even on extremely uneven surfaces.
This crane can be built in three days, considering that all the necessary components are prepared in advance.
In the gearbox, the following gear ratios are used: 1 to 30 and 1 to 35.
A three-phase motor with an output power of 600 watts is used. The total weight of all installations, excluding counterweights, will be approximately 250 kg.
The main part of the construction is made from used building materials, but new cables and bearings are used.

This crane can easily lift 150-200 kg.
