Abstract

PURPOSE: At a system for hoisting long single cuptals of metal or semiconductor out of fused material, unbalance signal propositionate to the length of the hoisted material is applied to a hoist-load detecting bridge circuit. In this way, is assured the constant traverse area of the material being hoisted.
