SAFE AND EFFICIENT HOISTING

摘要

Blair multi-rope hoists can be used as production or service hoists. Blair multi-rope hoists are also known as multi-rope drum hoists. They can use either one (single) or two drums. A multi-rope drum hoist is similar to a drum hoist - but each drum uses two ropes to handle the load which, in turn, adds certain complications. Two ropes carrying the load provide for a higher payload (but not double the payload). Blair hoists are preferred for depths above 2000 m and payloads above 13 000 kg. Since this type of hoist is an expensive hoisting solution and is only suitable for very deep mines, they are not applicable for use in coal mines.
