"Working at the mine has been both interesting and challenging over the years," said Glen Torjusson, Senior Planner, Mine Maintenance at Highland Valley Copper. "Our employees had to work smart when we were trying to survive low commodity prices and today we are benefiting from those practices."

Glen Torjusson is responsible for all mobile equipment on the mine site. The current production fleet consists of two Letourneau large front end loaders, 30 Caterpillar 793 haul trucks, a backup fleet of Caterpillar 789 haul trucks as well as 11 Caterpillar dozers, 6 Caterpillar graders and a full complement of service vehicles. No rest for these massive machines – the mine runs 24 hours per day, 365 days per year in extreme temperatures ranging from -40°C (-40°F) to 40°C (104°F).

Late in 2001, Glen was having problems with the wet brakes and transmissions on his haul trucks. High ambient temperatures were reducing the viscosity of his existing oil, accelerating brake wear and warping brake discs. He approached major oil suppliers looking for new and improved lubricants to meet the challenge.

Wade Hordal is the General Foreman at Highland Valley. He maintains four P & H 2800 Shovels, two BE 295 BI Shovels,and three BE 49R Rotary Blasthole Drills, with two 495BE and one 49HR to be added to the fleet.

"Before we switched, we had one grease for each season, which sometimes overlapped, requiring some form of hybrid. We even had to have a second product on board for bearings. So, needless to say, we used to change grease a lot," Wade says. “We were looking for one single product for our open gears and bearings and when Petro-Canada came on board that’s what they had to offer."

PRODURO TO-4+ Synthetic All Season

Petro-Canada formulated PRODURO TO-4+ Synthetic All Season, a multigrade oil which, when coupled with Highland Valley Copper’s effective preventative maintenance program, not only improved the component life of the large Caterpillar 789 and 793 haul trucks but helped cut Highland Valley Copper's oil consumption in half.

VULTREX OGL

Formulated to excel in multi-service applications, including shovel, dragline, excavator, drill and haul truck applications, VULTREX OGL greases are designed to withstand the challenging operating conditions of mine equipment and meet or exceed major OEM requirements.

Technical Support

Petro-Canada is one of the few companies who provide a shovel technician – a full-time Petro-Canada employee – to their customers. Their shovel technicians provide timely, on-site solutions that extend equipment uptime, reduce maintenance costs and give the best return on investment.

"It’s reassuring to have someone come and take a look at how we are applying the product and to train our people," Wade says. "Ron Reiniger, our shovel technician, will suggest changes and give us tips on the application of the product. We see him every couple of months and he’ll stay with us for a couple of days."
