摘要： An elevator within a tower, such as a wind tower, includes a traction or drum type hoist powered by an electric motor where the hoist provides the mechanism to cause the vertical ascent or descent of the elevator. An aspect of the invention is to allow the descent of the elevator to drive the electric motor arranged to act as a generator and provide regenerative braking as well as power to drive an alarm device or devices.

摘要： A climb assist system is disclosed that dynamically adjusts the rate and level of assist of a climber as the climber's needs may change over the period of traverse of the ladder. A sensor detects the state of a person, such as the load exerted by the climber on a ladder associated with an assist rope, to provided an upward support force on the climber to compensate the climber's weight. Additionally, a sender is provided to transmit the load data to a receiver and a receiver to receive the data from the sender. A controller interprets the received data and thereafter provides control through a controlled motor and drive to provide energy to the assist rope.

摘要： A system for stabilizing the vertical motion of an object in a wind power generating tower comprises at least one static guide, and a guide component attached to the object, e.g., an elevator car, constrained to the proximity of the static guide. In addition, at least one further containment, e.g., a wirefϊx, coupled to the static guide is able to pass through the first containment as the object moves vertically in the tower. Moreover, the further containment is disposed to maintain the static guide in a fixed relationship to a mounting structure, and the further containment is disposed for in-situ attachment.

摘要： Disclosed is an apparatus, system, and method for sensing the current supplied to a motorized hoist for raising a maintenance platform and providing an estimate of the operating status of the motor, for example, as stopped, starting, stalled or operating as expected. In various embodiments, measures of voltage and current may be used to determine the operating condition of the hoist and to estimate the magnitude of the applied load. Unintended modes of operation can then be determined so that the conditions can be indicated to the operator and protective measures taken.

摘要： A restraint device is disclosed that limits the movement of the cable or rope relative to the traction, thus reducing or eliminating the popping noise associated with the cable or rope snapping back against the traction sheave. In one embodiment, the restraint device comprises a molded component that is fitted to encompass the region of the sheave where separation of the wire rope from the sheave is most likely to occur. The restraint device may be mounted so that it is removable and replaceable with minimal dismantling of the hoist containing the sheave. The restraint device may be reversible so that one restraint device may by used for at least two cycles before being replaced. Indication of the need for replacement may be provided by including a second color material at the depth where wear reaches the allowable limit, thereby providing a visual signal to initiate replacement as seen during service.
