The jib crane is composed of bracket, jib installation, rotating installation and electric hoist (chain electric hoist). The bracket is fixed on the wall or steel structure column and can be rotated according to user needs. The rotating part is divided into manual rotation and electric rotation. The electric hoist (chain electric hoist) is installed on the cantilever track and used for lifting heavy objects. Jib cranes are widely used in light and small lifting occasions in mines, workshops, assembly lines, warehouses, and docks. The utility model has the advantages of novel structure, reasonableness, simplicity, convenient operation, sensitive rotation, light weight, sensitive load movement and the like. The operation of this machine is realized through the handle control button, which controls the lifting and horizontal walking of the electric hoist trolley.

Jib crane installation:
Before installing the crane, check whether the tortuous and torsional deformation of the jib beam, the corrosion of the shaft, and the impact damage caused during transportation should be corrected or repaired separately. In addition, shafts, bearings and other rotating parts are cleaned and lubricated every six months. For cantilever beam installation, please proceed in the following order. Drill holes on the wall or steel structure column according to the drawings. Lift the main cantilever with a crane, fix the cantilever with the upper and lower support plates with fixing bolts, measure the upper deflection with a spirit level, and then tighten the nut on the rotating shaft clockwise. The electric hoist, traveling block, and slewing are installed on the cantilever beam track. All electrical appliances on the cantilever beam should be connected and installed with a power cord of appropriate length.
