ABSTRACT:
In a powered V-sheave hauling system, purposively spaced enlargements on the line permit automatic disengagement of line and sheave when any desired point on the line reaches the sheave. The line is then held from running backwards under its load. The invention is particularly directed towards the avoidance of stresses or damage when a load has been fully pulled in.
