发明名称 HOISTING DEVICE
摘要 The invention relates to a hoisting device for use at a wind turbine, in particular for use in a wind turbine nacelle, which hoisting device 1 comprises a reel 4, a drive motor 12, control means 14 and a hoisting line 6. The hoisting line is a rope, which comprises synthetic fiber material, e.g. a high-tech rope. Hereby it is achieved that the hoisting device can be provided in a compact form, compared with traditionally used hoisting means, since the synthetic rope used as a hoisting line is characterized in having a high tensile strength and a low weight, whereby a rope having a comparable low weight can be used for lifting the same load, for which traditionally a steel wire having a relatively large weight has been used. Further, since the weight of the rope itself is relatively small, a drive motor, gear etc. having reduced capacity, power etc., can be used as compared to a traditional hoist, thereby also aiding in reducing the size, weight, complexity, cost etc. of the hoisting device.
