The Northern Bermuda Triangle

Today CVRD Inco is still involved in product development, albeit in a different capacity. Most of the equipment in Sudbury leaves the factory fully assembled. If it’s going to be lowered in a cage, a few tricks must be performed. Depending on the size of the cage, this can mean tearing the machine down, lowering the pieces on the cage and rebuilding it underground. It’s an extra process that can cost the mine as much as $30,000.

CVRD Inco wanted to prove new machines above ground. It created a ramp with a 20% grade in an old open pit mine near Sudbury.
It’s been called the Bermuda Triangle of the North because things happen to vehicles on the ramp test that never occurred in the past. The vehicles are pounded repeatedly by worst-possible situations that replicate real-world conditions. The Canadian Standards Assoc. (CSA) and other groups spell out specifications like safe stopping distances. CVRD Inco’s test uses the standards, then cuts them by a third to make up for extended maintenance intervals.
