Abstract
1409585 Balancing slewing jib-cranes CREUSOT-LOIRE 26 July 1973 [9 Aug 1972] 35713/73 Heading B8B A crane comprises a support structure 1, rotatable about a vertical axis on a chassis 2, carrying a jib 3, a fixed counterjib 4, a pulley system 5 for luffing the jib 3, a pulley system 6 enabling the counterjib 4 to be placed in position, and a balancing system 7. As shown, the chassis 2 is mounted on endless tracks but may alternatively be mounted on pneumatic tyres, Fig. 3 (not shown). The balancing system comprises a beam 7 in a circular arc centred on the vertical axis of rotation and, in the embodiment shown, is in the form of an I-girder anchored by its lower flanges to the ground. A retaining stay 9 is fixed between the upper end of the counterjib 4 and an anchoring device 8 including a carriage running on, and retained by, rollers engaging the upper flanges of the I-girder. Arms 10 connect the carriage to the support structure 1 so that the device 8 follows the slewing movements of the crane. The device 8 may be moved by the slewing movements of the crane or may incorporate a motor drive to slew the crane by its own movement along the beam 7. For transport the crane may raise the beam 7 itself either through the pulley system 6, Fig. 7 (not shown), or by the jib 3, Fig. 8 (not shown).
