Abstract (en)
[origin: EP1733994A1] A lifting device (1) comprises a support (2), a platform (3) for taking a load and a lifting frame (5) that is connected between the support (2) and the platform (3). The lifting frame comprises a scissor mechanism (5) that is provided with scissor arms (7,7a) which are interconnected in a crosswise pivotable manner. The scissor mechanism can move between a collapsed position and an extended position for raising and lowering the platform (3) with respect to the support (2). A load measuring system (11) is provided for measuring the load on the platform (3). The load measuring system comprises at least two levers (14,15,15a) and a transmission mechanism (30). Each lever (14,15,15a) is connected to the upper end, facing the platform (3), of a respective upper scissor arm (7a) so that it can pivot about a lever pivot axis (17). The levers (14,15,15a) are coupled together by the transmission mechanism (30) for transmitting said torques to one another.
