A flexible bandlike member extends about the cable on the sheave, and has both ends connected via linkages to an eccentrically mounted bell crank on an auxiliary sheave. One cable end, after passing around the drive sheave, engages a portion of the auxiliary sheave circumference, translating the auxiliary sheave eccentrically and pulling both ends of the bandlike member when the cable is loaded.
