Description

technical field [0001] The invention relates to a hoisting device used for installing a large-scale wind power generating set. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind is a non-polluting energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. [0003] my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW. Among them, the onshore w...
