A forklift truck has a drive wheel (3) and lateral support wheels (4, 5). Each support wheel (4, 5) is arranged in a holder (14) which is rotatably mounted on a vertical pin (17). The pin (17) is longitudinally displaceable in a bushing (18) which is permanently connected to the forklift truck and has at the other end a plurality of end-side recesses (19) which are distributed over the circumference and have different depths. At the same time, in each case, pairs of recesses (19) of the same depth are formed which, viewed in the cross-section through the pin (17), are located opposite one another in such a way that the connecting line of the two depressions (19) intersects the central axis of the pin (17). The pin (17) has a radial through-bore in which a peg (20) which protrudes on both sides out of the through-bore is arranged, the ends of the said peg being arranged in the recesses (19) of an associated pair of recesses (19). The upper end of the pin (17) projects out of the upper end of the bushing (18) and is provided with a plate (21). Between the plate (21) and a shoulder (18a) which is formed on the bushing (18), a compression spring (22) is arranged. The forklift truck can be easily matched to different operating conditions by means of the vertical adjustment of the support wheels (4, 5) which is made possible in this way. <IMAGE> |
