The load leveling device of the present invention comprises an elongated frame assembly having an elongated track frame therein. A carriage assembly is movably mounted to the track assembly for moving longitudinally along the length of the track assembly. A lead screw threadably engages the carriage assembly for causing the movement of the carriage assembly along a track frame. An attachment link is connected to the carriage assembly and is adapted to be connected to a lifting device. The opposite ends of the frame are adapted to be connected to the load. In a modified form of the invention, three of the load leveling devices are connected together with one of the devices having the opposite ends of its frame connected to the movable carriage assemblies of the other two devices.
