Grab Crane Parts

The grab bucket overhead crane consists a few main parts encompassing bridge, grab hoist trolley, crane running mechanism and electric control system.

Bridge: this metal structure is composed by main beam and end beam. The main beam utilizes a box-shaped structure that is formed by U-shaped groove and I-beam group. The end beam is connected to the main beam by M20 high tensile bolts for the purpose of convenient storage and transportation.

Hoist trolley: it is the unit for raising and lowering goods as well as running horizontally along bridge girder. Generally there are two sets of electric hoists mounting to the trolley, one is used for lifting items up and down, and the other is for opening and closing the grab bucket. The electric hoist falls in two primary types, wire rope hoist and chain hoist, and the former is more often adopted.

Crane running mechanism: it drives the entire crane to move back and forth along runway beam. The running mechanism adopts separate driving modes, which is completed by conical rotor with brake motor or electromagnetic brake solid rotor motor. The running speed can be 20, 30, 45 m/min.

Electric control system: it is the unit that supplies power for the functionality of the crane. The electrical system design should take a few things into account, such as the reliability of lifting, durability and safety precautions.
