BHP Cage Winder Upgrade
Nickel Mine
Leinster, WA
The Cage Winder at Leinster is the designated “secondary means of egress” for the mine. It consists of a “100 man” cage with counterweight. The Cage is used to transport the workforce into and out of the mine each shift to minimize transport time and maximise production time.
Key criteria - Safe, shortest change-over option
Winder - Double Drum, Cage and counterweight, Mine depth 1,100m with 13 operating level
Scope - Winder DC drive, Brake System, Control System, Safety System
How - To facilitate the shortest shutdown possible, a new equipment room was built and all equipment installed. This allowed the full winder systems to be pre-commissioned prior to shutting down the winder.
