Operator compartment assembly

A movable cab structure and operator's compartment for a front end loader which permits complete access to all parts of the front end loader for easy servicing, repair or replacement work. In one embodiment, each base frame side member of the front end loader includes an elongated rail, a stop, and a bracket having a roller mounted thereon. Each side wall of the operator's compartment also includes an elongated rail and a roller which is mounted to the side wall by a bracket. As the operator's compartment is moved forwardly, the rails on the compartment side walls engage the rollers on the base frame side members while the rollers on the compartment side walls engage the underside of the rails on the base frame side members. The operator's compartment may then be easily moved forwardly to an extreme position until the rollers on the compartment side walls engage stops on the base frame side members. In a second embodiment, the cab structure is movable longitudinally on the side walls of the operator's compartment to an out-of-the-way position. Each compartment side wall includes a roller on its forward end for engaging an inwardly turned lip extending along the length of the cab structure. Each side of the cab structure includes a rear roller which rides along the upper end of a respective compartment side wall. In yet another embodiment of the invention, each base frame side member includes an upstanding flange member which forms a rail wherein the entire operator's compartment is capable of longitudinal movement. Rollers are uniquely arranged with respect to the rail to provide a simple effective mechanism that permits the operator's compartment to be moved forwardly.
