Elevator travelling cable elevator cable

 

 

Introduction

1.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. Elevator traveling cable is a specialized multi-conductor cable continually in motion and must last for many years.  A generally accepted life span is 20 years – or 3,000,000 flex cycles.
2.Traveling cable is typically mounted in the elevator hoistway, where each end is terminated, and alternately takes the full load of the suspended cable as the car moves up and down.  Machine room termination is becoming widely accepted because it eliminates the junction box along with the labor and reliability issues associated with it.

A number of elevator cable designs and installation techniques are available.  The elevator contractor must work closely with the cable manufacturer’s application engineers to insure the use of best product for the application.
