Abstract
A method and apparatus for repeatedly testing wire rope and sheaves under simulated operating conditions is disclosed. The testing apparatus is capable of simulating many conditions under which wire ropes and sheaves are used in actual practice with cranes or the like including adjustments for varying rope tension, rope speed, sheave speed, sheave off-lead angles relative to the rope and to allow reverse bending of the rope. Sheaves of different diameter and different rope size and materials may be tested.
