Development Of Winches With Wet-type Multi-disk Brakes

摘要

Drum-brakes (dry-type-brakes) have been used for conventional winches on mobile cranes. However, this kind of brake presents problems in terms of performance, size and maintenance under severe operating conditions. KOBELCO CRANES CO., LTD. has developed a new winch with a wet-type multi-disk brake (free-fall brake) to solve these problems. New crawler-cranes, equipped with these new winches, are now being commercially produced. These new winches have achieved a widespread favorable reputation in the market.
