ABSTRACT:
A system or structure for supporting a construction rig, such as a crane or the like, is formed with four bearing members each of which is maintained in contact with a ground formation over which the rig is to be moved by deflective action of the support structure. In the operation of the device, when a first bearing member is deflected relative to a reference plane, a second bearing member located diagonally opposite the first bearing member is deflected relative to the reference plane in the same direction by approximately the same distance. At the same time, a third and fourth support bearing member of the support system are each deflected relative to the reference plane in a direction opposite to the direction in which the first and second support bearing members are moved by approximately the same distance as the first two support bearing members.
