摘要
The lifting device, in particular for laboratory apparatus, has a supporting element (6) which can be raised or lowered. The element is fitted with means of attachment and with an actuating mechanism (5) for displacing the element. Movement of the supporting element (6) is effected by an at least approximately horizontally movable element (5). Here this element has the form of a lever (5), for example a pivoting lever. In the region of the console, a mass (4) which can be moved, for example swivelled, by the element (5), with incorporated flywheel (4) is provided. Connection to the supporting element (6) is achieved by a cable- or chain-type body (3). The supporting element has the form of a truck (6) designed to be displaced along a stand profile (2). For the purposes of weight compensation, the truck (6) is attached to the ends of a laminated spring the other ends of which are fixed to the stand. This lifting device, in particular for rotary evaporators as well as laboratory lifting platforms, is light, rapid and safe to operate and possesses greater stability than devices of equivalent dimensions, even under a wide range of loads.
