Because retarder action relies on oil shear in the space between the discs, there is no additional wear to the discs. The brake system has a dedicated hydraulic circuit providing filtration and cooling. The fan for the cooling system is software controlled to find the best bal- ance between cooling, performance and fuel consumption. The Doosan DA40-5 has multiple drivetrain improvements. A bolt-on rear differential replaces the previous one- piece rear axle, reducing power loss to the wheels. Improved gear ratios reduce axle speed, extend component life and minimize vibration. The sum of the changes equals better operator comfort and improved fuel efficiency. Better dumping Dumping the bin requires several steps, but they're the same steps over and over all day long and are therefore perfect for automating with advanced electronics. machine matters | continued Rubbertrax_EW0117_PG.indd 1 12/7/16 8:36 AM While Doosan introduced a bolt-on rear differential and improved gear ratios on the new DA40-5, they kept their trademark front-mounted turning ring, tandem rear bogie and independent front suspension that work together to keep all six wheels on the ground and driving in even the most challenging terrain.
