Abstract
A suspension member load sensor configured for use with a suspension member in an elevator system is provided. The suspension member load sensor includes a housing bounded by an upper cover plate and a lower cover plate. The upper cover plate and the lower cover plates are configured to receive a rod extending therethrough. The lower cover plate is configured to seat adjacent a mounting plate. A strain gauge is disposed within the housing and configured to produce an electrical signal commensurate with a load on the suspension member. A plurality of spaced apart projections extend outwardly from a lower surface of the lower cover plate. The projections are configured to define a location for the introduction of force into the load sensor.

A suspension member load sensor configured for use with a suspension member in an elevator system, the suspension member load sensor comprising:
- a housing bounded by an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plates configured to receive a rod extending therethrough, the lower cover plate configured to seat adjacent a mounting plate;
- a strain gauge disposed within the housing and configured to produce an electrical signal commensurate with a load on the suspension member;
- and
- a plurality of spaced apart projections extending outwardly from a lower surface of the lower cover plate, the projections configured to define a location for the introduction of force into the load sensor.
A suspension member load sensor configured for use with a suspension member in an elevator system, the suspension member load sensor comprising:
- a housing bounded by an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plates configured to receive a rod extending therethrough;
- a strain gauge disposed within the housing and configured to produce an electrical signal commensurate with a load on the suspension member;
- an upper swash plate in contact with the lower cover plate, the upper swash plate having an annular race located on an upper surface, the upper swash plate configured to receive a rod extending therethrough;
- and
- a lower swash plate in contact with the upper swash plate, the lower swash plate configured to receive a rod extending therethrough and further configured to seat against a mounting plate;
- wherein the upper swash plate is configured for rotation relative to the lower swash plate.
An elevator fixture configured for use with a plurality of suspension members in an elevator system, the elevator fixture comprising:
- a plurality of suspension members configured to support an elevator car;
- a suspension member socket connected to each of the suspension members;
- a threaded rod extending from each of the suspension member sockets;
- a mounting plate having a plurality of apertures configured to receive the threaded rods extending therethrough;
- a lower swash plate configured to receive one of the rods extending therethrough and further configured to seat against the mounting plate;
- an upper swash plate in contact with the lower swash plate, the upper swash plate having an annular race located on an upper surface, the upper swash plate configured to receive one of the rods extending therethrough;
- and
- a suspension member load sensor configured to receive one of the rods extending therethrough and further configured to produce an electrical signal commensurate with the load on the suspension member.
