Description

 Purposes and features:


The THJ series of spring type hydraulic rail clamping device (hereinafter referred to as rail clamping device) is a safety device against wind to prevent the heavy-duty mechanical equipment traveling along the track being run away under the wind force. This product applies to bucket wheel stacker and reclaimer of stockyard and coal yard as well as bridge-type, gantry-type, container cranes and other rail mounted cranes. When the crane is stopping, the rail clamping device will automatically clamp the track under the action of the spring and the sliding friction will make the crane resist the wind force. When the crane is normally operating, the hydraulic device will make the clamping tong open, and the crane may free travel.
