Abstract: A weight-measuring device (1) for vehicle lifting platforms, which can be arranged between a height-adjustable supporting element (15) and a vehicle which is to be lifted, wherein an upper part (2) and a lower part (3) form a cavity (12) which is filled with a hydraulic fluid (13) and/or with a gas and generates in the cavity (12), by means of a load (19, 20) lying on top, a hydraulic or gas pressure which is measured and/or indicated with a pressure gauge and/or indicator device (4) which is at least partially integrated in the upper part (2) and/or in the lower part (3), with the upper part (2) being composed of rubber and/or of plastic and/or of some other elastic material.

Abstract: Support element for lifting platforms, which can be arranged between a carrying element of the lifting platform and a vehicle which is to be raised, wherein the support element can be removed from the carrying element, wherein the support element rests on at least one vertically displaceable transfer element that seals a pressure chamber that is filled with hydraulic fluid and is disposed above said transfer element, with the transfer element generating in the pressure chamber a pressure that is characteristic for the weight resting on the support element, and in that the pressure chamber has an annular recess, in particular a groove, which is sealed by the equally annular transfer element.

Abstract: The invention relates to a bearing element for lifting platforms, which is a displaceable part of a bearing arm of a load receiving element of a lifting platform, with a vehicle bearing element resting on that end of said bearing element that protrudes from the carrier, wherein at least one annular recess, in particular an annular groove, is arranged on the upper side of said bearing element, in which at least one vertically displaceable transfer element is disposed that seals a pressure chamber that is filled with hydraulic fluid and is disposed below said transfer element, with the transfer element generating in the pressure chamber a pressure that is characteristic for the weight.

Abstract: A hydraulic vehicle lift system includes at least one hydraulic vehicle life and one hydraulic drive unit for lifting and lowering the at least one vehicle life. The hydraulic vehicle lift system is characterized in that the hydraulic vehicle lift system has at least one further hydraulic vehicle lift and at least one further hydraulic drive unit for lifting and lowering the at least one further hydraulic vehicle lift, and in that the hydraulic vehicle lifts can be hydraulically connected to the respective other hydraulic drive unit in order to be lifted and lowered.
