T-shaped load traverse for use in crane to handle rotor blades of wind energy plant, has roller, eyelet and stop point connected to lifting point, where length of section of load connection unit between lifting and stop points is changeable

摘要

The traverse (10) has a deflection roller (18), a stop eyelet (24) and a stop point connected to a lifting point (22) of a lifting device i.e. crane, by a load connection unit i.e. rope (16). Length of the load connection unit is changeable between the stop point and the lifting point, where a length of a section of a load connection unit between the lifting point and the stop pivot point is changeable by a length changing device. The length changing device is designed as a rope winch, a hydraulically cylinder (14), a pneumatically actuated lifting cylinder or a spindle drive. Independent claims are also included for the following: (1) a lifting strap for handling of rotor blades of a wind energy plant, comprising a pulling device (2) a method for assembling or disassembling a rotor of a wind energy plant using a load traverse and a lifting strap for handling of rotor blades.
