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.

Abstract: A suspension member equalization system is provided. The suspension member equalization system includes cylinder assemblies configured to receive rods extending from suspension member sockets. The cylinder assemblies have slidable pistons. A manifold block is in fluid communication with the cylinder assemblies. An incompressible fluid is in simultaneous communication with the cylinder assemblies and the manifold block. An upper swash plate is received within a cavity formed in a lower portion of each of the cylinder assemblies and in contact with the cylinder assemblies. A lower swash plate is received within an annular recess of each of the upper swash plates in a manner such that the upper swash plate is rotatable relative to the lower swash plate. The pistons within the cylinder assemblies are configured for movement such as to seek an approximately equal pressure, thereby approximating equal tension in each of the suspension members.
