<p>A lifting device (1) having a liftable and tiltable platform (2) for pallets or any other arbitrary load preferably has floor-supported frame (3). The lift arm (4) provided with a cylinder unit (4a, 4b) and the tilt arm (12) provided with a cylinder unit (12a, 12b) are each at the one end pivotable around the same shaft (5). The lift arm (4) is connected to a link arm (7) via a pivot (6) between its point of connection (8) with the frame and a connection point (9) with a mounting piece (10) projecting downwards from the load platform. Also the tilt arm is connected thereto in a pivot point (13). In the lower position of the platform (2) link arm (7) and tilt arm (12) extend substantially horizontally and parallel to each other, the link arm (7) uppermost. The central load-receiving portion (2a) of the load platform (2) can, when the lifting device is in its lower position, be located roughly level with or insignificantly above the floor surface, whereas the lift and tilt arms are housed within portions (2b, 2c, 2d) of the platform and with inverted U-shape. In an upper position the load platform can be tilted downwards about 45° and upwards about 5°.</p> |
