According to ABB, this represents a milestone for the mining industry, as one of the two production hoists will have the largest production capacity in the world, able to transport payloads of 75 tonnes. Its six ropes will be able to support the heavy loads from 1 km underground at a maximum speed of 18.3 metres per second, supported by dual 7,700kW motors.
As the mining industry evolves to keep up with increased demand, this project represents a breakthrough in enhanced productivity, the Swedish group added.
The service shaft and production shaft have both been sunk in preparation for the hoisting systems. ABB supplied two hoists to the service shaft, including the cage. At the same time, it delivered the hydraulic braking system as well as electrical controls and powertrain for a temporary Blair cage hoist being commissioned in the…
