I DA U N I V E R S A L J a n u a r y - Fe b r u a r y 2 0 1 6 19 NUTS AND BOLTS NEWS Nuts & Bolts continued on page 21 Construction equipment: e new DL200-5 and DL200TC-5 (tool carrier) are the fi rst Doosan wheel loaders with a hydrostatic drive system – in place of the traditional torque converter transmission. e "dash-5" wheel loaders replace the "dash-3" models, transitioning from an interim Tier 4 to Tier 4-compliant diesel engine. ey off er improve- ments in fuel effi ciency, operator comfort, serviceability and reliability. Like their predeces- sors, customers can choose between two li -arm designs. e 142-net-horsepower DL200-5 wheel loader is built with a standard Z-bar li -arm linkage system, which is ideal for digging, heavy li ing and general construction tasks. e DL200TC-5 wheel loader has a parallel-li -linkage system to help the wheel loader operator keep the load level through the entire li cycle. Both the DL200-5 and DL200TC-5 have a 2.6 cubic- yard bucket capacity. New hydrostatic drive system A new hydrostatic drive system in the DL200-5 and DL200TC-5 wheel loaders replaces a torque converter transmission. A hydrostatic drive system off ers several advantages over the torque converter system, including: • Improved fuel effi ciency be- cause of higher performance at lower engine rpms • Enhanced machine positional control increases productivity • Reduced wear on the brakes as dynamic breaking automatically slows the wheel loader Doosan Wheel Loaders add Hydrostatic Drive system Selectable power modes DL200-5 and DL200TC-5 wheel loader operators can select between three power modes that adjust the maximum engine rpm. Unique to the hydrostatic drive system, the engine rpm is not directly correlated to the machine's travel speed, so the maximum travel speed remains unaff ected. • Power: Provides superior power and performance for tough con- ditions and truck-loading tasks • Standard: Balances fuel con- sumption for everyday digging, grading and li ing tasks • Economy: Reduces fuel consumption for low-demand ap- plications Traction control management Doosan DL200-5 and DL200TC-5 wheel loader opera- tors can easily adjust traction force to match jobsite condi- tions to reduce wheel slippage for a more effi cient operation in digging, stockpiling and loading applications. Operators may choose from the following traction modes. • Max: Provides maximum trac- tion force • Traction control: Allows the wheel loader operator to choose from three levels of reduced traction forces to match jobsite conditions • S-Mode: Helps when operating on slippery roadway conditions Wheel loader operators may instantly return to the machine's Max traction mode by pressing the kick-down button on the joystick control. Speed management e new speed management feature allows DL200-5 and DL200TC-5 operators to obtain full engine rpm for optimal li arm or hydraulic attachment performance, yet fi ne tune the maximum machine travel speed via seven present levels within fi rst gear, up to eight mph. Auto-shutdown Doosan added an auto- shutdown system to its new DL200-5 and DL200TC-5 wheel loaders to help owners and opera- tors save valuable fuel during non-working conditions. Opera- tors can confi gure the idle time before auto shutdown, from three to 60 minutes. When enabled, the feature will shut down the wheel
