What’s introduction of anchoring device of gantry crane?
The crane and rail foundation are fixed by the anchoring device , as usual, the device is set on the rail each part. 
When the wind attacks, the crane drives to the place of anchoring device, the gantry crane and anchoring device
are fixed by anchoring mast in order to protect the gantry crane.
The anchoring device can’t anti-wind timely, especially when the wind attacks, it’s hard to stop and anchor.
So it’s usual as automatic anti-wind rail clamp. As usual, the crane works in the air, when the wind speed exceed 60m/s,
we must adopt anchoring device.
Except the rail clamp and anchoring device, there are kinds of anti-wind device, however, the following requirements must be met:
1. the self-locking condition of the components’’ gravity or spring to make rail clamp’s anti-climbing come true.
2. the anti-wind can make sure the wind can’t blow the crane away at non-working.
