Abstract
A crane with luffing system, in which at least two front pulleys are present, slightly interspaced from each other. Over the front pulleys run hoisting ropes to a hoisting trestle carrying the load hook. The hoisting trestle is connected to a slewing table via a torsion-resistant rope frame. The slewing table is composed of two separate plates rotatable relative to each other, of which the lower one is connected via a torsion-resistant rope frame to a container spreader to which a container may be secured. Through rotation of the lower slewing plate relative to the upper one it is easy to accurately maneuver a container suspended by the crane.
