<p>The crane has chassis frames (1, 1') for holding a mast (10) and movable on rails (4, 4'). A lift truck (1'') is arranged on the mast in a vertically displaceable manner, and the mast has two supports (11, 11') arranged at a distance from each other in a movement direction of the frames. The supports are connected with one another at a mast profile through a crossbeam (12) and made from light metal profiles, where the crossbeam is connected to the supports in a bending-resistant manner. The frames comprise a traction drive system that is arranged in an inner side of the mast profile.</p> |
