<p>The frame (1) comprises two arms (11) which carry front wheels (2) spaced from the upright (6) in forward direction. Across the frame (1) extend upper and lower rails (17 and 18, respectively) for guiding displacement of the upright (6). The upright (6) is connected to a runner (19) guided by one of the rails (17) and to a working cylinder (20) connected to that runner (19). The working cylinder (20) is directed substantially transversely to the upright (6), one end of the working cylinder (20) is connected to the upright (6) adjacent the front thereof and the other end of the working cylinder (20) is connected direct to the runner (19). Advantages: simple construction, good view of the area of the load carrier, lowered centre of gravity and a construction of short structural dimensions. <IMAGE></p> |
