Produced for single girder gantry crane rail clamp manual for double girder gantry crane electro-hydraulic rail clamp, stabilizing the product quality, easy installation. Welcome to inquire. Rail clamp with a locomotive is connected via the rear clamp shaft hole, locomotive travel, drag (push) folder to move rail synchronous movement, guide wheels under the weight of rail clamp pressure can roll along the serpentine track, and by guide wheel bracket, the guide rail clamp clamp whole shaft driven at a fixed axis floating along the track surface. Automatic rail clamp automatically locks the gantry crane on the track, in order to prevent accidental slip sometimes by force. Rail clamp automatically open in carts traveling state, other states automatically clamped. The control system uses Siemens PLC control. Without changing the original premise of operating action by the PLC system running and stopping the crane running gear, brakes and brake open, rail clamp clamping operation and so on and implementation of automatic control, improve the overall stability and safety. Outdoor crane crane safety device to prevent under strong wind glide along the track. Usually connected to clamp together the crane base structure, sandwiching both sides of the head rail to prevent sliding. Rail clamp sub-manual and electric type two (see photo). Manual rail clamp screw is generally simple structure, but the clamping force is small, slow movements, mainly used in small area of ??the windshield on the crane SMEs or temporary use. Large crane or harbor cranes mainly electric rail clamp. It is made by a lever or by a hammer spring force clamp clamping rail, the hydraulic system by loosening the clamp cylinder force. Heavy hammer bulkier, large dimensions, the clamping force smaller than the spring, the work is not as smooth spring-loaded. When the electric spring rail clamp electrically interlocked by crane anemometer, a wind when the wind speed reaches cytometry can not guarantee the normal operation of the crane wind scale (usually corresponding to 6 to 7), crane power, clamp grip track. This highly reliable rail clamp work.
