Apparatus is disclosed for moving an automatic teller machine and the like between a retracted position and an extended position to provide access to the back of the machine for servicing. The apparatus essentially comprises a stationary frame and a moving carriage supported by the frame. In the retracted position, the front end of the carriage is coextensive with the front end of the frame. In the extended position, however, the front end of the carriage is cantilevered beyond the front end of the frame. In order to move and support the carriage, especially in the extended position, there is a shaft freely rotatable in a pair of bearings at the front end of the frame on which the carriage rides. The back end of the carriage rides within the frame's rails, which prevent the carriage from moving up or down but otherwise freely allows lateral movement. By turning the shaft with a hand crank or a small motor, the carriage with the teller machine can easily be moved between retracted to extended positions.
