A device for detecting at least a motion parameter of an elevator of a wind power installation

摘要

The apparatus (1) for detecting at least a motion parameter of an elevator (2) of a wind power installation (wea), which elevator (2) an elevator car (4) which, along a substantially at the upper end (5) attached to the supporting cable (7) is movable along its travel path, the load-bearing cable (7) at the upper end (5) and opposite lower end (8) is held under tension and a driven drive pulley (10) at the elevator car (4) is looped around at least partially, by means of the device (1) as the movement parameters of the delay can be determined and from this by additionally taking into account of at least one car mass and, if appropriate, additional mass drive capability of the drive pulley (10) and / or braking of the drive can be effectively.
