Abstract

A wheel-mounted load lifting and transporting machine having load engaging means 10 at its front end and a counterweight 11 at its rear end, is distinguished by an interacting mobility between the counterweight 11 and the load-engaging means 10 by which the tilting moments imposed upon the machine by the counterweight 11 and by a load 12 suspended from the load engaging and lifting means 10, at all times offset one another with the result that throughout changes in the location of the picked up load 12 with respect to the wheel locations 9, a line that passes vertically through the center of gravity of the loaded machine is substantially equispaced from the points at which the wheels 8 of the machine rest upon the ground. For optimum handling of the machine, each of the wheels 8 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. <IMAGE>
