ABSTRACT:
A remote control handle assembly for remote control of a powered dolly, with the control handle assembly including a handle mount which rotatably mounts a pair of handles. The powered dolly has a pair of spring-centered valves and a pair of mechanical push-pull cables extending between the handle mount and the valves, with a movable inner cable of each push-pull cable connected one to each of the handles. Rotation of one handle controls forward-reverse direction of travel of the powered dolly and the rotation of the other handle controls steering, with the rotational axes of the handles being structurally related whereby one handle counteracts the rotational torque of the other handle.
