The invention relates to a weight-compensating device comprising a support ( 1) and a component (2) which is mounted on the support (1) and is movable particularly in a vertical direction by means of a drive unit. The inventive weight-compensating device is characterized by the fact that at least one negative pressure body (3) is disposed between the support (1) and the component (2), said negative pressure body being modifiable in length and being connected to a source of negative pressure in order to compensate the weight acting on the component (2). |
