Assignee:

Otis Elevator Company - Farmington CT

International Classification:

F16D 6900

US Classification:

188250G, 187370, 187375

Abstract:

An elevator safety brake for stopping an elevator car is provided with a brake shoe having a molybdenum alloy friction surface for contacting an elevator guide rail surface to provide a stopping force. The molybdenum alloy contains 99. 4 weight percent molybdenum, 0. 5 weight percent titanium and 0. 1 weight percent zirconium. The friction surface of the brake formed from the alloy exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.

International Classification:

B66B 7/08

US Classification:

187411, 187277

Abstract:

A connector device () for making electrically conductive connections with at least one tension member () in an elevator load bearing member () includes a spacer member () that establishes physical spacing between portions () of the load bearing member (). In one example, each portion () includes one tension member (). A holding member () secures the portions () in a selected position relative to the connector device. At least one electrically conductive connector member () makes electrically conductive contact with at least one of the tension members () to facilitate a selected electricity-based monitoring technique for accessing the condition of the load bearing member.

International Classification:

F16D 6900

US Classification:

188251A

Abstract:

An elevator safety brake for stopping an elevator car is provided with a brake shoe having a carbon-carbon composite friction surface for contacting an elevator guide rail surface to provide a stopping force. The friction surface of the brake formed from the carbon-carbon composite exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.

International Classification:

F16D 6900

US Classification:

188251M

Abstract:

An elevator safety brake for stopping an elevator car is provided with a brake shoe having a fused sprayed friction coating for contacting an elevator guide rail surface to provide a stopping force. In a preferred embodiment, the coating is obtained by plasma spraying an admixture of 85 weight percent nickel-chromium alloy particles and 15 weight percent tungsten carbide particles on a substrate. The plasma sprayed admixture is fused. The fused sprayed friction surface of the brake exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.
