MECHANISM FOR DETECTING ALIGNMENT, RISING LIMIT AND LOWERING LIMIT OF ROPE TO HOISTING DRUM OF WINCH BY FEED SCREW

摘要

PROBLEM TO BE SOLVED: To detect alignment winding, a rising limit and a lowering limit of a rope with a simple mechanism. SOLUTION: The rising limit and the lowering limit are detected by a projection part 4 arranged in a horizontal moving body A and a position detector 5 arranged on the left and right by aligning the rope to a hoisting drum by a rope guide 1 arranged in the horizontal moving body A installed in a feed screw 3 for rotating by interlocking with the hoisting drum 7 of a winch.
