Wind turbine tower cranes are about to become the main force in the new plan of wind power hoisting field. Larger tonnage crawler crane or split hoisting methods can be used to solve the problems of height and weight, but these two solutions will prolong the construction period of fan hoisting and greatly increase the construction cost. While the wind turbine tower crane has stronger hoisting capacity, higher working height, lower earth bearing force, higher anti-wind ability, smaller working space and faster operation speed.
