The sample is a "traveling cable" for use with elevators and similar conveyances. The outer sheath contains four separate, shielded pairs each of which is contained within their own sheath. The cable can be used with indoor campus wiring systems via non-specified termination systems.

The complete cable assembly was tested against the requirements of S008:2001 including those which apply to cables for fixed campus installations. The requirements of AS/NZS1979:1993 were not applied and this report must not be used to compliance with AS/NZS1979.

Elevator Traveling Cable: Design Evolution

Elevator traveling cable is a vital link between the elevator car and controller. In conventional elevators, all power and signal information is transmitted through the traveling cable. The vast majority, as much as 95%, of wire and cable produced will be installed in a fixed location. The remainder will be used where some motion is required. Many of these cables are easily replaceable, with no serious consequence from any failure. The remaining flexible cables - in motion during service, such as mining cables, oil well boring cables, crane cables and elevator traveling cables - are expected to last.

Load Control in Elevators

This article offers an interesting global vision of the present state of the electronic systems for load weighing in elevators, the different applications and requirements for each installation, its basic principles and the future tendencies that the market for these devices will demand, given the importance and necessity to equip each elevator with these systems.
