Qualified for the job
“We’ve got 13 logging loaders that run on the Series 60—and most of them are factory remanufactured. We’ve been pleased with their performance. So we decided to switch to the Series 60 for our yarder tower,” says Pete Dahlgren.
Hauling heavy trees from the forest requires an engine that can handle heavy stress and long operational hours, making Series 60 engines from Pacific Power Group perfect for the job. The engine’s reliable performance and superior construction make them well suited to challenging conditions. The 630 HP Series 60 remanufactured engine selected for this yarder tower provides the performance, smooth operation, low maintenance and extreme power and torque that’s required for logging the tough terrain around Forks.
Off to a flying start
The repowered yarder tower has been hard at work in the forest since January. Recently Joe Grycko from Pacific Power put it through its paces and analyzed its engine data. “This is quite a step up. When the yarder throttles up to fourth gear, running 1800-2000 rpms, those logs are flying up the hill at 60 mph on those cables. The cable drum spins at a very high rate of speed with the new drivetrain,” says Joe. “The original transmission was a Berger 3-speed. Now, they have a 6-speed Allison transmission provided by U.S. Transmissions, a dealer of Pacific Power Group. The result is much more horsepower, which translates into faster line speed and more production.”
And for a logging company, productivity is everything. “Logging is not a straight line. We go up a hill, then down a hill. When there’s a slowdown in any part of that process, you’re not making any money,” says Pete Dahlgren. “The yarder tower is our most important piece of equipment. Now, it’s bringing the wood up the hill much faster. Our landing site gets buried in logs, and we can barely get enough trucks up there to carry them away. It’s doing what it needs to do, and doing it well.”
