ELEVATOR RAIL RETAINING DEVICE

摘要

In an elevator, a guide rail is used to guide the ascent and descent of ascending/descending objects such as an elevator car or counterweight. Said guide rail is held against an elevator shaft wall by a rail retaining device. The disclosed rail retaining device has a bracket, which is affixed to the elevator shaft wall, and a retaining fixture, which holds the guide rail in the bracket. The retaining fixture allows the guide rail to rotate, with respect to the bracket, due to horizontal loads. The rail retaining device is also provided with a moment generation member which generates a moment that works to correct flexure in the guide rail caused by horizontal loads.
