 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
 Less energy consumption
 Less space required
