Classification of cranes

Lifting machinery used in bridge construction projects can be generally divided into light and small lifting equipment, bridge type lifting machinery and boom type cranes, and cable cranes according to their different structures and performances. Light and small lifting equipment such as: jacks, pneumatic hoist, electric hoist, balance hoist (also known as balance hoist), hoist and so on. Bridge type lifting machinery such as beam cranes, etc. Boom type cranes such as fixed slewing cranes, tower cranes, truck cranes, tire cranes, crawler cranes, etc. Cable cranes such as lifts.

1. According to the nature of lifting: mobile crane, tower crane, mast crane.

2. According to the driving mode: one type is centralized driving, that is, one motor drives the long transmission shaft to drive the active wheels on both sides; the other type is separately driven, that is, the active wheels on each side are driven by one motor. Medium and small bridge cranes mostly use the "three-in-one" drive method in which brakes, speed reducers and motors are integrated. For large bridge cranes with common lifting capacity, universal couplings are often used for the drive device. .

3. According to the structure: the crane is mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), jib type (self-propelled, tower type, gantry type, railway type, pontoon type, mast type crane) ), cable type.
