Abstract
The invention relates to a crane which can be raised quickly and automatically. The cable (13), anchored on the boom tip (12), is reeved between two trains of pulleys (14) and (15). The train (14) is integrally connected to the foot (9) of the boom. The spindle of the train (15) slides in a slide channel (19) in the mast, under the action of a pusher (20). The angle (39) opens slowly at the beginning of the raising and quickly at the end of the raising. Application: possibility of a very long boom tip (12). <IMAGE>
