Description

Purposes and features

    MQQKD series of self locking type rail clamping device (hereinafter referred to as rail clamping device) is the crane safety device against wind developed according to features of many traveling wheels of crane, low wheel pressure and high resistance against wind. Switch on the power supply. The clamping tong of the rail clamping device is lifted by the power supply to be separated from the track by a distance. Now, the crane may be normally operated. When the crane is not working, press the button and the clamping tong may be automatically lower down under the gravity. When the crane travels left and right, the eccentric shaft on the clamping tong may be pushed to make the clamping tong have torsion and clamp the track. The higher the wind force is, the higher the resistance is. The higher wind force causes mechanical self-locking operation for braking protection.
