Molybdenum alloy elevator safety brakes |
摘要 |
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.
