The order is for the design, manufacture, supply to site and commissioning of the double drum, single clutch hoist, complete with all electrical controls and drives, which are being sub-contracted by DavyMarkham to power and automation group ABB in Montreal.
Capable of handling payloads up to 36,000lbs, at speeds of 2,200ft per minute and hoisting distances down to 4,140ft, it will be operated initially in single-line mode for skip hoisting duties throughout the shaft sinking stage, then converted to normal double drum configuration for transporting personnel during production. Powered by a directly connected 4,000 HP AC motor, it meets the latest Ontario and Canadian H&S standards for mining plant and is designed with replaceable drum shells, plate liners and rope risers, enabling it to be reutilised in a deeper shaft should the future need arise.
