Based on multiple previous hoist upgrades, Nidec was able to work with the installation contractor to install much of the hardware ahead of the scheduled shut down, thereby reducing the required downtime. Nidec was also able to retain the existing hoist motors which saved the customer capital expense and weeks of lost production. The analog system was replaced with a digital system which is less prone to drift or the need for periodic recalibration. With the upgrade to the new drive system, Nidec can dial in to the machine over the internet and provide instant support, even though the mine is located in a remote part of Northern Ontario.
Nidec met the customer’s expedited start up window and provided a reliable and supportable hoist system.
