Abstract
The invention relates to a spreader bar () for distributing a lifting force from a crane () onto a two lifting regions () f a load () to be lifted. The spreader bar comprises a frame () and first and second systems (). Each system comprises a lifting pulley (), a connector () for connecting the spreader bar to the respective lifting region via a main wire () guided by the lifting pulley, an actuator () for vertically moving the connector via an actuator wire (), and a movably arranged suspension element () connecting the actuator wire and the main wire. A compensator () compensates for possible fluctuations in the vertical distance between the respective lifting region of the load and the spreader bar. Such fluctuations can be due to the crane or the load being located on a floating vessel. When the suspension element is engaged with a blocking element (), the lifting force from the crane can be transferred to the main wire in order to lift the load.
