Abstract: An electrical inspection system for an elevator load bearing member includes an electrically conductive, low resistance wrap located at the load bearing member, contacting the load bearing member around a circumference of the load bearing member. An inspection unit is configured to apply an electrical current through the load bearing member and determine an electrical resistance of the load bearing member, and is electrically connected to the load bearing member at the wrap to distribute electrical current uniformly therethrough. A method of determining an electrical resistance of a load bearing member of an elevator system includes applying an electrically conductive low electrical resistance wrap entirely around a circumference of the load bearing member. An inspection unit is connected to the load bearing member at the wrap. An electrical current is applied through the wrap into the load bearing member to determine an electrical resistance of the load bearing member.

Abstract: A method of fault detection of a belt or rope includes interconnecting a plurality of cords of the belt or rope, the cords including a plurality of wires, to form a bridge circuit. A fault detection bridge circuit is subjected to a voltage excitation and outputs a voltage which is indicative of the belt or rope damage but remaining insensitive to other environmental noises.
