What are the Main Components of Lifting Mechanism of Gantry Crane and Overhead Crane?
In general, the lifting mechanism of a gantry crane/overhead crane is mainly composed of driving, braking, transmission, hook and safety devices.
1.Driving Device
Driving device of lifting mechanism is the dynamic power to realize the lifted goods up and down. Most of crane kits adopt electrical driving, which all mechanisms are driven by motor.
2.Braking Device
Braking device is an important component for gantry crane and overhead crane. Braking is always installed on a high-speed shaft to protect the lifting mechanism.
3.Transmission Device
Transmission mechanism is set on trolley frame, including transmission shaft, coupling, reducer and etc.
4.Coiling System
Steel wire ropes circled out from coiling block and connect with the hook over pulley block, thus they are a completion of a coiling system of gantry crane or overhead crane.
5.Load Handling Device
Load handling device is also called spreader, which includes hook, grab bucket, electromagnetic chuck and etc. The most widely used is hook.
6.Safety Device
Safety device of gantry crane/overhead crane usually means overload limiter and lifting capacity limiter.
