Double Beam 80ton China Rail Mounted Gantry Crane
The mobile container crane mainly consists of gantry structure, long traveling mechanism, trolley, electrical device, power supply system, container spreader.
Gantry cranes can be operated from the ground via cable-connected control pendant, radio remote control or from an operator’s cabin.
In addition, multiple controls are possible by switching control from one mode to another.
The system allows operation of the crane in a manual, semi-automated or fully automated mode.
Further confusing the issue is that gantry cranes may also incorporate a movable beam-mounted hoist in addition to the entire structure being wheeled, and some overhead cranes are suspended from a freestanding gantry.
