BHP Billiton has selected technology and automation group ABB to build the world's largest mine hoisting systems for a potash operation in Canada.
In a statement ABB said the four hoist systems would be made for the Jansen Potash Project and would be delivered over a period between 2015 and 2018.
ABB said once completed the equipment would be “the largest mine hoists ever designed and manufactured,” measuring over six metres in diameter each, with a total connected power close to 14,000kW.
“Equally impressive are the service shaft hoists which are electrically identical to the production hoists but will carry smaller payloads,” the company said.
“The complexity and ultra-high performance requirements of the brake systems on these massive hoisting systems requires the development of new mine hoist brake system technology.”
The contract includes development of all mechanical components, as well as electrical systems and motors, and both ABB and BHP agreed to jointly develop a safety plan to cover the contract.
