Steel wire ropes have an interface function in the traction lift

Steel wire ropes have an interface function in the traction lift. The ropes influence the dimensioning of the rope drive as well as other themes such as costs, energy efficiency, shaft space, production, installation and maintenance. Smaller rope diameters will decrease the diameter of the traction and the diverter pulleys. The use of steel wire ropes with a diameter below 8mm and a ratio of diameter pulley to rope D/d below 40 will open new possibilities in lift system construction. Steel wire ropes covered by materials with higher friction coefficient will allow to reduce wrapping angle of the traction pulley and to avoid the sharp traction grooves. Flat and slim terminations for steel wire ropes have the advantage in increased lifetime avoiding incline angles on the pulleys. Additional the method for calculation of the expected number of trips has to be improved especially for complex rope courses in the lift system. Certificates issued by Notified Bodies are necessary to show the suitability of new products in lifts. The influence of new rope products and methods and their linking-up will be presented.
