Drive mechanism for a track mounted body

摘要

A drive mechanism for a body where the body has a plurality of load bearing and track engaging wheels that allow the body to move back and forth along a track that comprises an actuator attached to the body that is manually or mechanically driven, a non-load bearing drive wheel that is attached with respect to the body so that it engages a stationary surface adjacent the body and a drive coupling means between the actuator and the drive wheel wherein actuation of the actuator causes rotation of the drive wheel which moves the body along the tracks. The invention provides a convenient means of attaching a drive mechanism to a body and to enable easier movement of track mounted bodies.
