cylindroconical drum

A combination of a cone and a cylinder. The ascending rope is wound on the smaller diameter of the cone; as the engine reaches full speed after the period of acceleration, the rope is wound on the larger cylindrical part. For deep shafts the rope is wound back on itself for the last part of the hoisting period, thus reducing the width of the drum.
