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.
A climb assist system is disclosed that adjusts the rate and level of assist of a climber and starts/stops the level of assist as the climber needs may change over the period of traverse of the ladder. A sensor may detect a change in the operating state of a motor in the climb assist system. For example, the change in state may indicate a change in the load exerted by the climber indicating that the climber intends to start or stop an active climb. The climb assist system may then adjust the inputs to the motor to initiate a climb or terminate a climb.

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.

(1) Adjustable climb assist systems consisting of a compact motor and drive control, with user interface, for use in tall structures to offset the weight of a climbing worker.
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.

A rigging, operable to raise and lower the platform, passes through a restraint device comprising a tension holder. The tension bolder comprises a first body having a substantially planar face surface and a rear portion having a divot disposed therein. A second body, substantially similar to the first body; and having a substantial!y planar face surface; is disposed in a substantially facing arrangement with the first body to permit a line to pass between the substantially planar face surfaces. A lever is disposed in the divot of the first body and is operable to draw together the substantially planar face of she first body and the substantially planar face of the second body whereby friction can be selectively applied to the line when the line is disposed between the substantially planar first surface and said substantially planar second surface.

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.
In various embodiments, an apparatus is disclosed comprising a platform, a hoisting machine mounted on the platform, and a rigging operable to raise and lower the elevator platform, said rigging passing through a fairlead, said fair lead stabilizing said elevator platform to a single location proximate a top of said elevator platform, said fairlead comprising two separable parts wherein said separable parts can be placed around said rigging without accessing an end of said rigging. Such a fairlead improves the serviceability of the equipment and reduce down time for replacement of a worn or damaged fairlead.
