A pivot mounting assembly is provided including a pivot arm (5) hinged to a pivot base (3) for mounting a load in a vertically adjustable manner. A first force-providing device (13) is hinged with its first operative end to the pivot arm and is supported with its second (17) operative ends on the pi

A pivot mounting assembly is provided including a pivot arm (5) hinged to a pivot base (3) for mounting a load in a vertically adjustable manner. A first force-providing device (13) is hinged with its first operative end to the pivot arm and is supported with its second (17) operative ends on the pivot base for providing an antitorque moment to at least partially compensate for a torque imparted by the load on the pivot arm. The pivot base is provided with a support surface (27) in which the support location (49) for the second operative end is shiftable. A second force-providing device (36) is provided for generating a shifting force the second operative end of the first force-providing device.
