The base (6), on fixed-down feet (7) spaced 2 m apart, supports, on a turn-table ring (14) with a traversing motor (16), a turret (3) with bolt-on winches (15,3) for jib (21) and load (22) cables passing over pulleys on the two-section main turret member (2,2'). 320 m of lifting rope, giving effectively 160 m clear lift, is provided. A drum separable from the winch for transit purposes minimises component weight.Winch frames, integrally incorporated in the turret structure to save weight, support the electrical control cabinet (5). The radius of action is varied from 6 to 12 m by bolting on additional jib sections (8,9,10...), giving capacities between 3000 and 1000 kg. |
