Abstract: A lifting truck with a telescoping mast and a balancing cylinder is disclosed. The stages of the mast are each constructed with three vertical beams. A mechanism for extending the mast are contained in or near the side beams. The balancing cylinder exerts an upward force to counter the dead weight of the telescoping stages and other parts of the truck that are lifted. The balancing cylinder is connected to the lower portion of the first stage and the upper portion of the second stage. The beams making up the stages of the mast can be tubular or U-shaped to allow space for the balancing cylinder and/or hydraulic lines or control leads.

Abstract: Arrangement at truck mast constituted by three mutually telescopically moveable parts (1, 2, 3), which each include three vertical beams (4, 5, 6) placed in the corners of a triable. Between the middle mast part (2) and the fixed lowest mast part (3) a balance cylinder (11) is arranged in the central beam (5) of the next to the lowest mast part (2).
