By Driven Device For Transporting Material To A Stationary, At Least In Part, Accumulating Means For Subsequent Release Into Chamber By Gravity Patents (Class 414/167)
  • Patent number: 6505785
    Abstract: The apparatus of this invention is utilized for mounting a wind turbine on the upper end of a wind turbine tower. The invention also relates to the method of erecting the same. The tower is provided with a pair of guide rails positioned on opposite sides thereof which extend from the lower end to the upper end of the tower. A sled is movably mounted on the guide rails and has a platform mounted thereon which is adapted to support the wind turbine thereon. In one form of the invention, the sled is self-contained in that it has an engine and a winch mounted thereon. In another form of the invention, the winch and engine are mounted on a self-propelled vehicle which is designed to transport the sled from one tower location to another. In another form of the invention, the winch is detachable from the self-propelled vehicle so that the winch may be anchored to the ground.
