Furnace Door Winches | Custom Built for a Copper Smelting Plant
Thern supplied five 4HP Series winches used to open and close five furnace doors at a copper smelting plant. A unique rigging arrangement provided an economical solution with two wire ropes attached to a single drum, allowing one winch to operate each door. Specialized motors were developed to withstand the corrosive environment.
16,500 lb. line pull was required to operate the doors at 20 feet per minute and a travel distance of 15 feet.
