Abstract
An electric drive mechanism for a body, wherein the body has a plurality of load bearing track engaging wheels that allow the body to move back and forth along a track. An electric motor drives a non-load bearing drive wheel that is attached with respect to the body so that it engages a stationary surface adjacent the body through a drive coupling means between the electric motor and the drive wheel. Actuation of the electric motor causes rotation of the drive wheel which moves the body along the track. Typically a first controller controls the movement of the body in one direction and a second controller controls the movement of the body in the other direction. Other features include a low power warning system, the inoperability of other motors when one is being operated and a disable facility if a motor has not been active for some time.
