Abstract
The disclosure relates to a lifting apparatus comprising a first scissor pair (20) formed by first arms (22a, b) which are rotatably journalled in one another in a journal (24), and a second scissor pair (21) formed by second arms (23a, b) which are rotatably journalled in one another in a journal. A frame (30) is carried by the two scissor pairs. The upper and lower end portions of opposing arms of the scissor pairs are interconnected with first and second upper crossbars (26, 28) and first and second lower crossbars (27, 29). A prime mover (15, 16) is rotatably connected via an arm (36) to a sleeve-like device (37), which is rotatably disposed about the first lower crossbar (29). A mechanical transmission device (43, 45) is fixed to the sleeve (37) in an angular relationship to the arm of the sleeve, the transmission device (43, 45) being disposed in order to abut, with the frame in its lowermost position, against an arrest member (41) provided on upper end portions of a first scissor arm (22a) and a second scissor arm (23a) located above the sleeve (37), in order, on lifting of the frame (30) to exercise an upwardly directed force against the arrest member (41), this force being created by the momentum the sleeve (37) transmits to the mechanical transmission device (43, 45) on rotation of the sleeve (37) by the prime mover (15, 16).
