Classification Of Diesel Engine Crane

The hoisting machinery used in bridge construction projects can generally be divided into four categories: light and small hoisting equipment, bridge type hoisting machinery, boom type crane and cable crane according to their different structures and performances. Light and small hoisting equipment, such as jack, pneumatic hoist, electric hoist, balance hoist (also known as balance hoist), winch, etc. Bridge type lifting machinery such as beam crane. Boom type cranes such as fixed slewing cranes, tower cranes, truck cranes, tire cranes, crawler cranes, etc. Cable cranes such as elevators.

According to the lifting nature, it can be divided into mobile crane, tower crane and mast crane.

According to the driving mode, one type is centralized driving, that is, a motor drives the long drive shaft to drive the driving wheels on both sides; The other is separately driven, that is, the driving wheels on both sides are driven by a motor. Medium and small bridge cranes often adopt the "three in one" drive mode, which is composed of brake, reducer and motor. In order to facilitate installation and adjustment, universal coupling is often used as the drive device for ordinary bridge cranes with large lifting capacity.

According to the structural form, the cranes are mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), boom type (self-propelled, tower type, portal type, railway type, pontoon type, mast crane) and cable type.
