Abstract
A wheel-mounted load lifting and transporting machine having load engaging elements at its front end and a counterweight at its rear end, is distinguished by a novel interacting mobility between the counterweight and the load-engaging elements by which the tilting moments imposed upon the machine by the counterweight and by a load suspended from the load engaging elements, at all times offset one another with the result that throughout changes in the location of the picked up load with respect to the wheel locations, a line that passes vertically through the center of gravity of the loaded machine is substantially equispaced from the points at which the wheels of the machine rest upon the ground. For optimum handling of the machine, each of the wheels on which it is mounted is steerable and power driven to the end that the machine can be moved in any direction and along any defined path.
