The suspended track traffic has the advantages of small investment, small occupied area, full utilization of urban space resources, capability of meeting the requirements of medium and small traffic and the like, receives more and more attention, and gradually opens part of test lines to study related systems.
The car stopper is a track traffic safety device which is arranged at the end of a line, prevents the car from slipping and protects the safety of a train. There are many different types of car stops in conventional railway, subway and the like tracks, including friction, slip, hydraulic and the like. However, there are relatively few car stops in suspended rail transit. Therefore, it is very necessary to design and invent a car stop suitable for suspended rail transit.
