Plastic lining materials for multi-rope friction sheaves
Abstract
With the use of multi-rope hoisting systems with friction pulleys, there is a need for new materials suitable for lining the grooves of rope driving pulleys of hoisting machines. The most common lining materials – wood (oak) and rubber-fabric conveyor belt – have insufficient coefficient of adhesion with steel rope (respectively 0.17 and 0.25) with unsatisfactory service life (3‑5 months). The coefficient of adhesion of lining materials with steel wire rope should not be lower than 0.3 and should not decrease when the rope is wetted; allowable specific pressure on the lining should not be lower than 25 kg/cm²; service life of lining – at least 5 years; lining should not wear out the ropes and catch fire during prolonged slippage of ropes and should be elastic enough.
