Description

technical field

[0001] The invention relates to the field of ground passenger cable cars, in particular to a safety protection system for passenger ground cable cars. Background technique

[0002] The car of the ground passenger cable car is generally drawn by wire rope, driven by a winch with a large-diameter drum, and usually travels back and forth along a track with a certain slope. It can be used as a means of urban public transportation and as a sightseeing vehicle for tourists in scenic spots. Because of the flexible connection between the traction system and the car, and its special structure, major safety accidents may be caused by broken ropes, overspeed, and signal transmission failures. Because it involves the safety of passengers, the reliability of its safety protection system has become the focus of most attention during the design, manufacture, installation, and acceptance of the cable car.
