Abstract
Description
technical field
[0001] The invention relates to the technical field of lifting equipment, in particular to a self-climbing wind power maintenance crane. Background technique
[0002] Currently in the period of rapid growth of the wind power industry, wind power equipment is constantly developing in the direction of high power and high towers. Wind farms are mostly located in high mountains, Gobi, wilderness, offshore, shallow seas and other areas with inconvenient transportation and harsh environments, resulting in the demand for wind turbines. The equipment requirements for installation and maintenance are getting higher and higher, the operation difficulty is getting more and more difficult, and the lifting cost has also risen sharply.
[0003] The warranty period of wind turbines is generally 5 years. Almost all the fans installed during the explosive growth period have expired. The early design and manufacturing technology level is not high. After several years of operat...
