Abstract
The cab/pivot unit comprises an upper mast element associated with a pivot, an access platform which extends horizontally at one side of the mast element, and a driver's cab mounted pivotably about a vertical axis located at the side of the mast element and linked to this element. The cab is orientable manually (arrows F1, F2) through approximately 90° between an operating position, in which it is located in the extension of the access platform, in front of the mast element, and a transport position, in which this cab is folded above the platform, against the mast element. The invention is used for tower cranes with a “suspended” cab.
