Description

Technical Field

[0001] The utility model relates to the field of hoisting equipment, in particular to a hoisting beam used for a tower. Background Art

[0002] Offshore wind turbines are mainly composed of underwater foundations, towers, nacelles, hubs and blades. Cranes are required for offshore transportation or wind turbine installation. In order to facilitate the lifting of the tower, a lifting beam is commonly used. Currently, the lifting beams are generally of a single specification. However, due to the different diameters of the towers of offshore wind turbines, one type of tower is usually lifted and a pair of lifting beams are made. This cannot adapt to the use of towers of various specifications, so different lifting beams need to be equipped at the construction site to cope with the lifting of towers of different specifications. Moreover, when towers of different specifications need to be installed, the corresponding lifting beams need to be replaced, which is very troublesome, time-consuming and labor-intensive, resulting in reduced installation efficiency of offshore wind turbines.
