  • Transport module for the moving of heavy loads
    Patent number: 6202774
    Abstract: A simply-designed, multi-purpose transport module with which heavy loads can be moved over the ground has the following features: a frame, on which the load is laid, is positioned on the floor. A support is positioned on the floor. The ground loading pressure of the frame, on an increase of the ground pressure loading of the support, and the ground pressure loading of the support, on an increase of the ground pressure loading of the frame, can be reduced to below the unloaded weight through an actuator of the frame or of the support. The frame and the support have a first pair of inclined paths through which the frame can be supported on the support and the frame is displaceable horizontally with respect to the support on achieving a sufficient reduction of its ground pressure loading.
