Overview of project and ABB’s delivery
Rebuild of 4 mine hoists from DC-technology to
AC-technology plus 1 optional new hoist with
same AC-technology, all at sub-vertical level
(underground 740 – level)
Energy efficiency impact
Motor and drive operating at power factor = 1
Low Voltage drop, so that hoists can be started at
same time
Less transformer power required
Low level of harmonics
Higher efficiency
Customer benefits
© ABB Group Less energy consumption
Less space required

Editor's Notes
- <number>
New hoist is built on a new level above the old hoist while it was still running. Change over to new hoist was quick.
