Operating Your 20 Ton Gantry Crane
The 20t gantry crane can be operated remotely from the ground by means of remote control or pendant control, or within a cabin which is mounted to the crane. Before purchasing a crane, you should discuss this requirement with gantry crane manufacture and supplier to configure a proper lifting system for your specific use.
Pendant control – a control system that is typically attached to all overhead and gantry cranes. It utilizes a hard-wired pendant to operate the crane.
Wireless remote control – it allows the operator to work in a safe area by utilizing a handheld button box.
Cabin control – it is more often found in heavy-duty gantry cranes for a high-level efficiency and security. The cabin controlled gantry crane uses joysticks to control the movement of the crane.
U type double girder gantry crane parameters:
- Lifting Capacity: 5t~200t
- Span Length: 18~35m
- Lifting Height: 6~18m
- Working Class: A5, A6
- Traveling Speed: 38~44m/min
- Lifting Speed: 5.9~13.2m/min
We also provide a number of safety devices for your cranes to ensure a safe lifting operation, including:
- Anti-collision device: to prevent your gantry cranes colliding with each other or with the end of the runway.
- Overload limiter: to prevent the load exceeding the rated capacity.
- Limit switches: to prevent end stop collision or over-run.
- Rain cover: to protect the electrical device of your crane in outdoor workplaces.
