Since then, the company has conducted significant research and gathered input from customers to upgrade the models with additional features for increased productivity.
But one thing the company did not do was compromise its deliberately simple design.
The DA45 is powered by a Scania engine that achieves Tier 4-Final with SCR and EGR, but without the need for a DPF. It has a ZF transmission and is a full-time six-wheel-drive unit with limited slip front and rear differentials.
“This automatically engages whenever the machine detects any slippage,” Doosan product specialist Jay Patel says. “It will distribute power evenly to any side that needs that extra torque. It also has inter-axle diff lock, which is a push button in the cab. This runs longitudinally from the front to the rear of machine, and with this, let’s say you’re in the sand or going uphill and you have some slippage, it will distribute one-third of power to the front, to the tractor unit, and two-thirds power to the rear, and that will also allow you to keep contact with the ground and equally distribute torque to where it’s needed the most.”
Local 649 operator/instructors Andy Schaidle and Todd Keeler had constructed ramps, moguls, and an angled haul road on which to test the machine.
