A semi-automated load balancing mechanism includes a load balancing arm supported for vertical swingable movement and a second arm. The second arm is mounted on a distal end of the load balancing arm for horizontal movement. The second arm has a part holder on a distal end thereof for receiving and supporting a load thereon. An actuator is disconnectably coupled to the load balancing arm for moving it while allowing manual movement independent of the actuator.
