SASKATCHEWAN - ABB, with Canadian headquarters in St-Laurent, QC, has been selected by Australia-headquartered BHP Billiton to supply mine hoisting systems for the Jansen potash project, located 130 km east of Saskatoon.
The contract includes the overall design, manufacturing, supply and installation of four complete mine hoist systems to be delivered over a period between 2015 and 2018. This includes mechanical components as well as the electrical systems including ACS6000 AC drive systems and the high power, low speed synchronous motors. ABB is the only supplier of complete integrated mine hoisting systems including all mechanical and electrical systems.
The massive 6-metre-diameter friction hoists to be supplied for the production shaft will be the largest mine hoists ever designed and manufactured, each with a total connected motor power of close to 14,000 kW. Equally impressive are the service shaft hoists which are electrically identical to the production hoists but will carry smaller payloads. The complexity and ultra-high performance requirements of the brake systems on these hoists requires the development of new mine hoist brake system technology.
Once the four hoisting systems at the BHP Billiton Jansen mine are installed, ABB will have an impressive installed base of 11 complete friction hoisting systems, in Saskatchewan. In the area of underground mining the company has supplied over 700 mine hoist and automation projects and over 100 stand-alone hoist brake system projects, in more than 30 countries worldwide.
In Canada, (www.abb.ca) employs about 3,000 people in more than 45 centres from coast to coast.

At a diameter of 6 metres this will not be the world’s largest mine hoist. Far from it! There a number of mine hoists larger than the one proposed to be built by ABB.For example, the restored Nordberg bi-conical, cylindrical drum hoist at the Quincy mine near Hancock, Michigan is 30 feet (9 metres) in diameter.
When he says the largest, doesn’t mean the largest diameter but largest skip payload.
