Wire Rope Sheave Friction Effects on the Takeup Carriage Belt Tension by: Jeff Poe Mechanical Engineer, Precision Pulley, Inc., Pella Iowa ABSTRACT When a takeup weight is offset to the side of a conveyor, a wire rope is commonly routed from the take-up weight through a series of sheaves to the take-up carriage. The friction developed from a series of wire rope sheaves can effect the actual

Rope System Analysis By Stephen W. Attaway Abstract This paper presents an analysis of the loads in a typical climbing rope system subjected to a dynamic loading from a fall. Several examples are illustrated to show how to calculate the force on ropes and anchors subjected to dynamic loads that are experienced by a falling rock climber. The force in a rope that is generated when a falling
