  • Patent number: 5297645
    Abstract: An industrial lift truck having a body which includes a battery container cover, spaced straddle legs projecting from the body and a lift mast which moves along the straddle legs. The lift mast is moved along the straddle legs by a mechanism operated by a battery which is held in a container. The container is supported on a platform resting on the straddle legs and is moved along the straddle legs between a rear stored position and a forward open position by a hydraulic cylinder and piston. A guide arrangement for the battery container is located below the cover and is disposed internally of the end walls of the battery container to contact the inner surfaces of the end walls to direct the battery container during movement into the rear stored position and to prevent movement of the battery container transversely of the straddle legs when it is in the rear stored position.
