An arrangement for aligning a raised load has a rigid carrier element and tension cords secured to and extending down from the carrier element. The lower ends of the tension cords are provided for securing at load engagement points on the load. One tension cord has a length adjustment device extending between upper and lower connection points. The length adjustment device has a housing pivotably secured to the upper connection point. A drive shaft is mounted rotatably in the housing. A drive wheel, a friction disc brake, a load wheel, and a gear mechanism, coupling the drive shaft to the load wheel, are arranged on the drive shaft. The load wheel has over its circumference chain link cavities for individual chain links of a chain sling guided around the load wheel. The chain sling is secured by one of its ends at the lower connection point.

A measuring device for load sensing in a lifting-cable-based hoist, in particular a crane, having at least one pulley for deflecting the lifting cable of the hoist, a fastening means in the form of a cable loop, at the end of which the pulley is mounted so as to be rotatable about its roller axis, and at least one measuring element for sensing a force applied to the pulley.

A method for handling of an offshore wind turbine component includes using a vessel having a hull on which a motion compensating crane is mounted. The crane includes a main boom; a main boom luffing assembly; a mobile hoist cable suspension member; and a hoist winch and a hoist cable driven by the hoist winch. An object suspension device is suspended from the hoist cable. The mobile hoist cable suspension member is supported by a motion compensating support device that is fitted to the tip end of the main boom, the motion compensating support device including one or more motor powered motion displacement actuator assemblies and a motion compensating support device controller. The method includes connecting the offshore wind turbine component to the object suspension device; and operating the motion compensating support device to provide motion compensation in at least one direction of the object suspension device and the connected offshore wind turbine component. The crane is provided with one or more nacelle position detectors that are configured and operated to sense at least one of actual position and actual motion of the nacelle or of one or more components in or on the nacelle, and the one or more nacelle position detectors are linked to the motion compensating support device controller.
