ABSTRACT:
An industrial truck includes a tiltable lifting mast (1), a first tilting cylinder (2), and a second tilting cylinder (3). The two tilting cylinders (2, 3) are of double-acting design and are connected hydraulically in parallel. Two hydraulic lines (5, 6) are provided for the purpose of supplying hydraulic fluid to the tilting cylinders (2, 3). In order to simplify the design of the industrial truck, according to the invention the hydraulic lines (5, 6) open out at the cylinder base of the first tilting cylinder (2) and/or at a component (joint eye10) adjacent thereto, the cylinder base and/or the component (joint eye10) being formed at least partially as a hydraulic distributor.
