A load balancing manipulator is disclosed which allows the user great flexibility in moving heavy objects from place to place. The invention is supported on a base having an upstanding post to which is attached a pivoting arm having a second pivoting arm attached at a distal end of the first-mentioned arm. At the end of the second arm, a load manipulator is provided including a pneumatic cylinder-piston arrangement and a sleeve actuator for switches which, when closed, activate solenoid valves which control supply and exhaust of air to and from the cylinder, respectively. In the preferred embodiment, an electromagnet is used to hold a load in place. Battery back-up and load safety mechanism for the electromagnet are also provided.
