Device on the driver's cabin (18) of a crane. A bogie truck (20) is mounted on the gantry (12) so that it can move. The bogie truck is designed so that it embraces the gantry (12) and is provided with support wheels (22) that fit against the vertical beams of the gantry (12), which enter the trestlework of the gantry (12). The cabin is provided with a hoist (38), whose rope (40) is mounted on the upper end of the gantry. The cabin is mounted movably on bearing races (24, 26) on the bogie truck. The cabin can be rotated around the gantry by the motion along these races. The cabin can be moved up and down along the gantry, and rotated around it, so that the crane driver always has an advantageous working position with a good view. <IMAGE> |
