FR Interlock rotatable couplers have been widely applied in heavy unit freight wagons, and have improved the transportation efficiency significantly.
Main technical features:
- High structural strength, small coupling clearance, anti uncouple, interlock and auto centering functions, reliable function, good curve trafficability;
- An additional anti falling device and one auxiliary interlock device are under the hook head;
- Touch profile gap 9.5mm, 51% smaller than E type coupler;
- The bottom support at the front end of coupler can effectively prevent the broken coupler from falling onto the rail, resulting in major accidents.
