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
