This invention relates generally to hydraulic and electrical systems for aircraft belt loaders and more particularly to such systems with interlocks to facilitate efficient and safe operation. The present invention provides a hydraulic and electrical system for battery powered aircraft belt loaders which precludes actuation of the electric traction drive motors when the brake is applied or set, or without the operator seat being occupied, which precludes actuation of the belt conveyor if the brake is not set, which controls conveyor run time and requires that the conveyor be reset to neutral before being actuated the hydraulic pump to permit power steering when the operator seat is occupied, and which requires that the directional control lever for traction drive be reset to neutral after demounting the seat before the electric traction drive motors can be energized.

A multi-positionable rail for the conveyor of an aircraft belt loader having a rail supported by a plurality of parallel posts pivoted to the side wall of the conveyor and to the rail and collapsible under the force of gravity against a stop positioned on the conveyor side wall to a stowed position wherein the posts and rail are within the silhouette of the conveyor. A first support arm pivoted on the conveyor engages a first pin on a post to position the rail above the conveyor to function as a hand rail and a second support pivoted on the conveyor engage a second pin on a post to position the rail intermediate the stowed and hand rail position. A latch trapped on the post above the first pin is urged by gravity to engage the pin to prevent disengagement of the first arm from the first pin.
