摘要： The invention relates to an industrial truck comprising a chassis (6), which is supported by at least two front wheels (2) and by at least one rear wheel (3) on the ground (4), a mast (8) for a load-carrying apparatus (36), which is arranged in an upright position thereon in a mast support region (54) of the chassis (6), wherein the front wheels (2) are rotatably arranged on wheel arms (50, 50) that protrude forwards from the mast support region (54) of the chassis (6), and means (62, 64; 162, 164; 262, 264) for suppressing and reducing vibrations, wherein at least one of the wheel arms (50, 50), preferably both wheel arms (50, 50), is/are split into at least two wheel arm portions (50a, 50b), which are mounted by means of a bearing arrangement (56; 156) so as to be able to perform movements relative to one another, wherein the means for suppressing or reducing vibrations are designed or operable to influence relative movements of the wheel arm portions (50a, 50b), in order to ensure that any impacts owing to unevenness of the ground during travel can only be passed on to the chassis (6) and the mast (8) by means of the wheel arms (50, 50) in a reduced, and absorbed and damped manner, and that any mast vibrations are damped.
