Relevant knowledge of bridge crane

The use of bridge crane is of great help to construction operations. When using bridge crane, we should understand its relevant knowledge in order to make better use of its advantages.

Relevant knowledge of bridge crane:

The operating mechanism of the bridge crane has four traveling wheels (eight traveling wheels for large tonnage and special models, now taking four wheels as an example), which are respectively installed at both ends of the two end beams. Two of them are active wheels and two are passive wheels. The driving mechanism of the driving wheel is driven separately, that is, two sets of symmetrical and independent driving devices are used, which are installed on the walking platform of the crane.

The reducer of the crane's operating mechanism adopts fully sealed hard tooth surface, medium hard tooth surface and soft tooth surface reducers (used according to different working conditions), and the internal gears and bearings of the reducer are lubricated by oil bath. The oil level gauge and oil drain hole on the reducer are convenient for daily inspection and maintenance. And ensure that all reducers are free from shaft breakage, gear tapping and oil leakage under normal operation.

All mechanisms of the crane adopt rolling bearings, and the structural type of the brake is single push rod block brake. The brake wheel surface used is wear-resistant, impact resistant, has good heat dissipation performance, and the friction surface is smooth without defects. The friction lining of the brake has good contact with the brake wheel, good wear resistance and convenient replacement.

All parts of the crane mechanism are connected by gear couplings. In this way, even if the error caused by manufacturing and installation, or the displacement between components caused by the deformation of the bridge caused by load, can be compensated by the gear coupling, which will not affect the normal work of each mechanism of the crane.
