LATERAL OPERATOR RESTRAINT SYSTEM AND POSITION SENSOR FOR MATERIAL HANDLER

摘要

A self-propelled material handler (10) has a pivotally mounted boom (16) on a frame (12), and a cab (18) that is positioned adjacent the side of the boom (16). The cab (18) has an operator's entrance and exit opening (22) on a side of the cab (18), that is positioned to permit an operator to enter and exit the cab (10) and sit on a seat (20) in the cab (18). A lateral restraint bar (30) is mounted between the seat (20) and the cab opening (27), and is movable to a working position where it obstructs the cab opening (22) so that portions of the operator cannot be moved outwardly through the cab side opening (22) from the interior, and which pivots to a raised position to permit an operator to pass through the cab opening (22). When the restraint bar (30) moves away from its working position, a signal is provided to disable machine controls.
