Abstract

A transmission for movement along a track system comprises a frame movably supported on the track system by guides mounted to the frame. At least one endless belt assembly comprising a pair of spaced endless belts engaging associated belt wheels is mounted to the frame. A drive system for rotating the belt wheels and driving the endless belt is provided. A gripping system adapted for holding and releasing the track system is mounted between the pair of spaced endless belt. The gripping system comprises a plurality of posts extending between the spaced endless belts over the length of the endless belt assembly with gripping units slidably mounted on each of the posts. Biasing springs tend to center the gripping units on the posts. An actuating arrangement is provided for activating the gripping system. The actuating arrangement defines a gripping region adjacent the track system and allows the gripping units to engage the track system upon entering the gripping region and release the track system on leaving the gripping region whereby the gripping units hold and release the track system in order that the transmission pulls itself along the track system. The transmission makes it possible to navigate turns in a track system, particularly a cable system.
