Embodiment Construction

[0020] FIG. 1 exemplarily shows selected portions of an elevator system 20 . The car 22 travels in a shaft 26 with a counterweight 24 in a conventional manner. The load bearing member 30 supports the weight of the car 22 and counterweight 24 and interacts with at least one drive sheave of a machine (not shown) to facilitate the desired movement of the car and counterweight within the shaft.

[0021] Figure 2 exemplarily shows a portion of an example load bearing member 30, which is a coated steel strip. The example in FIG. 2 is for purposes of discussion and the invention is not necessarily limited to a particular type of belt or load bearing member. In this example, a plurality of tension members 32 extend longitudinally (ie, the direction L shown in FIG. 2 ) in the belt 30 . In one example, each tension member 32 comprises steel strands wound into wires in a conventional manner.

[0022] The tension member 32 is encased in a sleeve 34 which, in one example, comprises a po...

Abstract

A connector device (40) for making electically conductive connections with at least one tension member (32) in an elevator load bearing member (30) includes a spacer member (42) that establishes physical spacing between portions (38) of the load bearing member (30). In one example, each portion (38) includes one tension member (32). A holding member (50) secures the portions (38) in a selected position relative to the connector device. At least one electically conductive connector member (70) makes electrically conductive contact with at least one of the tension members (32) to facilitate a selected electricity-based monitoring technique for accessing the condition of the load bearing member.

Description

technical field [0001] The present invention generally relates to an electrical connector for establishing an electrically conductive connection with at least one tension member in an elevator load bearing member. Background technique [0002] Elevator systems typically include load bearing members, such as ropes or belts, which carry the weight of the car and counterweights and allow the car to travel within the shaft as required. Steel rope has been used for many years. Coated steel strips have been used in recent years, the strips comprising a plurality of tension members housed in casings. In one example, the tension member is a steel wire and the sleeve includes a polyurethane material. [0003] The new arrangement presents new challenges for monitoring the load-bearing capacity of the belt assemblies throughout the life of the elevator system. [0004] Various technologies are currently being developed to monitor new elevator belts. The present invention provides t...
