The Lidgerwood cableway steam hoist is equipped with reversible link motion, and the usual form includes two friction drums of large diameter, each being equipped with powerful band brake. These drums may be operated either together or independently, and the ropes travel at the same rate of speed when both drums are engaged ; the load may therefore be transferred at a uniform height for any distance along the cable, or raised or lowered at any point along the span. The conveying or traversing rope is carried either on a wide face drum, using separate in-haul and out-haul ropes with fixed ends, which run on or off the drum, or a curved drum is used, around which the conveying rope takes four or five turns to prevent slipping. A typical steam hoist is shown in the figure.
