Traction Technology for Elevators

In various industrial fields, energy and resource saving has been promoted, and also in the elevator industry, miniaturization of driving devices, lightness of cars, etc. have been pursued. Since these attempts reduce the traction capacity between the hoisting rope and the driving sheave, improvement in traction capacity by betterment of the friction transmission part is important. This paper describes friction and the wear mechanism between the hoisting rope and the driving sheave of a traction type elevator, further, the results of evaluation test of the new rope that makes substantial improvement in traction capacity possible.
