<p>An operator's cab for mobile machinery has front, top, bottom, back and opposed side walls. One side wall is pivotal about a generally vertical axis adjacent the front wall. The pivotal side wall can move between an inner position and an outer position to increase the width of the cab for operator occupancy or decrease the width of the cab to meet transportation clearance requirements. A flange projects laterally inward from the pivotal side wall to overlie an adjacent portion of the top wall. A roller carried by the flange, near the rear end portion of the pivotal side wall, is in rolling engagement with the top wall to support the rear end portion of the pivotal side wall. In a preferred embodiment, flanges projecting from the pivotal side wall envelop the outermost edges of the top, bottom and back walls, and dust proof sealing engagement is maintained between the flanges and the walls in either the inner or outer positions. A sliding access door is mounted on the pivotal side wall. An operator's control console, mounted on the pivotal side wall frame, projects inwardly of the operator's cab. This console extends over a portion of an operator's seat when the pivotal side wall is in the inner position but extends adjacent the operator's seat when the pivotal side wall is in the outer position. -1a-</p> |
