Hoisting device for the lifting of a vehicle or similar and comprising a rectangular supporting framework (2), a lifting beam (10), between which a hoisting jack (8) is placed. In order to maintain the lifting beam (10) in parallel arrangement with the supporting framework (2), there is a pair of pivotable fork elements (14, 15) extending between the supporting frame work (2) and lifting beam (10), and these elements are in communication with each other through force transferring means (16, 17) causing the fork elements (14, 15) to pivot synchronously but in opposite directions in a plane parallel with the longitudinal axes of the rectangular supporting framework (2). |
