1. Brief introduction:

  

1. Slewing boom 20t boom crane for light work, adopts column crane, rotary arm rotation drive device and electric hoist, the bottom of the column penetrates the concrete foundation through anchor bolts, and the cantilever rotates by the cycloid pin wheel reducer. The electric hoist beam on the cantilever extends straight from left to right and lifts the weight. Hollow boom crane for hollow steel structure, light weight, large span, large lifting weight, economical and durable. The crane is a new generation of crane equipment developed to meet modern production requirements. The jib crane adopts West German technology, which has the characteristics of reasonable structure, easy operation and high efficiency. Widely used in mines, workshops, warehouses, docks, etc.

2. Slewing cantilever 20t cantilever crane is mainly composed of top column, low column, main beam, main beam rod, electric hoist, rotating mechanism and electrical system. Button or both.
