Lifting unit for construction, maintenance and demounting of wind energy plants, has tower structure, such that outer side of tower structure is moved freely up and down, where tower shaft is trained for free movability of lifting unit

摘要

The lifting unit has a tower structure, such that an outer side of the tower structure is moved freely up and down. A mounting platform (2) is integrated in the lifting unit. A tower shaft is trained for free movability of the lifting unit, such that the hoisting machine moves freely on its outer side. The mounting platform and multifunctional multi daylight are integrated in a lower part of a hoist.
