Problems solved by technology

Wind turbine components can be bulky or difficult to handle, preventing manual handling of these components
Furthermore, wind turbines may be installed on uneven terrain and / or on very tall towers (e.g. towers at least 60 meters high), which are not accessible to mobile road cranes
In addition, the operation of mobile cranes is very expensive

Abstract

A portable crane assembly (300) for servicing a wind turbine (100). The crane assembly (300) includes a first primary support member (301) and a second primary support member (303) being rotatably attached to one another. The first primary support member (301) is configured to attach to a wind turbine component. The second primary support member (303) is coaxially rotatable with respect to the first primary support member (301). The crane assembly (300) further includes a boom member (304) pivotably attached to an end of the second primary support member (303). The portable crane assembly (300) is disassemblable into components that can be manually carried. A wind turbine servicing system and a method for servicing a wind turbine (100) are also disclosed.

Description

[0001] Cross References to Related Patent Applications [0002] This application claims the benefit of US Provisional Application No. 61083485, filed July 24, 2008, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to crane assemblies and methods for servicing and installing wind turbines and components thereof. Background technique [0004] Recently, wind turbines have received increasing attention because of their environmental safety and relatively cheap alternative energy sources. With this growing interest, considerable efforts have been made to develop reliable and efficient wind turbines. [0005] Generally, a wind turbine includes a rotor with a plurality of blades. The rotor is mounted to a casing or nacelle placed above a truss or tubular tower. Utility-scale wind turbines (ie, wind turbines designed to provide electrical power to a utility grid) can have large rotors (eg, 30 meters or more in leng...
