Zusammenfassung:	A load balancer having a load support arm with a power cylinder having a piston operably connected to the arm with a control circuit including a pilot operated valve for directing pressure fluid to the cylinder to maintain a constant pressure on the cylinder piston in all positions of the load support arm with means for limiting the rate of movement of said load support arm in the event that either the load is lost or there is a loss of fluid pressure acting on said piston when there is a load on the load support arm.
