1 October 2013 – The Zest WEG group’s small works division was recently contracted by Dymot Engineering to supply electric equipment destined for a kibble and stage winder application at a mine in the Democratic Republic of the Congo (DRC). The order included a floor standing panel with a WEG CFW09 variable speed drive (VSD) rated at 75 kW with dynamic braking and a full driver desk complete with a range of WEG LV switchgear for the kibble. Zest WEG Group also supplied a W22 55 kW 400 V electric motor and dual 11 kW motors with one control panel for the stage winder.

The Zest WEG group has a longstanding relationship with Dymot Engineering, which standardises on WEG motors to drive its winching systems. In 2012 Zest WEG group supplied a similar set of electrical control equipment to Dymot Engineering for the same DRC-based mine, and the success of this installation led to the second order. All this equipment has been supplied to underground contractor Bomar Projects which is establishing the mine’s shaft system.

The second order was more technically specific than the previous one, because it includes a separate braking resistor rated at 100% of the motor rating. This is a fast winch that will run continuously at 1.5 metres per second moving men and materials.
