    摘要： 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.

    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.

    摘要： A system configured for lifting or lowering a tool carriage device via a ladder climbing structure is described. The tool carriage device may be adapted to enclose and transport a payload and include a fall arrest grab with an overspeed brake to stop an uncontrolled descent of the carriage device. The tool carriage device may include obstruction sensors to detect an obstruction along the path of the carriage device.
