Abstract
In a tracked transportation system independent cars are drawn along by a common cable. A car comprises a rolling chassis with a cabin suspended above the chassis by a set of chains. The chains are coupled to a shaft forming apparatus for weighing the cabin and connected to an assembly for gripping the cable. The coupling between the chains and the gripping assembly can be released by a trigger device fixed to the track and operated by remote control to lower the cabin relative to the chassis and so achieve emergency braking.
