The upgraded interim Tier 4-compliant (iT4) DL200 and DL220 offer increased horsepower and performance improvements that enhance its capabilities for moving materials in highway, street, and paving projects, as well as building and site development.

More Power and Greater Fuel Efficiency

The 2.6-cubic-yard DL200 has been relaunched as a 160 hp iT4 wheel loader. It is engineered with a breakout force of 22,230 lbs., a full-turn tipping capacity of 17,110 lbs., and a dump height of 9 feet 6 inches. For those requiring additional dumping capabilities, the DL200 is also available in a high-lift configuration, extending the dump height 15 inches above the standard DL250, to 10 feet 9 inches.

The 3.0-cubic-yard DL220 has been re-engineered as a 160 hp iT4 wheel loader. It provides operators with a breakout force of 23,650 lbs., a full-turn tipping capacity of 18,480 lbs., and a 9-foot-3-inch dump height.

Both Doosan wheel loaders are equipped with 6-cylinder diesel engines that have been optimized for use with a cooled exhaust gas recirculation (CEGR) system, a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF). Engines with this configuration are optimized to reduce nitrogen oxides (NOX), and after-treatment is needed to reduce particulate matter to comply with iT4 emission regulations. The turbocharged engines feature a high-pressure common-rail (HPCR) design with direct fuel injection, electronic control, and four valves per cylinder.

This wheel loader’s new auto-idle feature provides additional noise reduction and fuel savings by reducing the working idle of the wheel loader from 950 rpm to a standby idle setting of 750 rpm when the machine is inactive for a short period of time.

Increased Performance

Designed with improved lifting performance, the DL200 and DL220 offer operators the ability to set upper and lower limits for both the lift arm and bucket stop positions from inside the cab. Better lifting capabilities improve cycle times in digging and loading applications, while providing better control of the lift arm and bucket positions. An optional fourth spool control valve provides operators the capability to utilize an attachment that requires an additional hydraulic function, e.g., some snow blowers and snow blades.

To keep the wheel loader running at optimal performance in dirty and dusty conditions, the DL200 and DL220 incorporate a new automatic-reversing cooling fan. The operator can select to reverse the fan via a switch, or it can be set to automatically reverse on a preset time frame. Each time the fan reverses, it will run in reverse for a few minutes to clean the cooling system. This results in longer working hours and shorter maintenance time to clean the cooling system.

Operators can also expect upgraded driving performance options. As an alternative to the standard limited slip differential, the DL200 and DL220 offer an optional hydraulic locking front differential. Based on ground conditions, the operator can choose to lock the differential manually with a floor-mounted foot switch, or allow the machine to automatically engage the system. This provides increased driving power when one wheel spins or loses traction and improves machine performance when navigating tough terrain.

The 542-cubic-inch engine increases the efficiency of fuel delivery via increased pressure. The increased pressure allows the injector to inject a finer mist into the engine, which results in a more efficient combustion that in turn produces more torque and improved fuel economy, less noise, lower operating costs and cleaner exhaust.

Service intervals on the front lift arm pins have increased fivefold, from 50 to 250 hours, reducing operating costs and downtime. Tilt cylinder hydraulic hoses have been rerouted for improved hose reliability, better hose movement and improved visibility to the attachment.

The DL200 and DL220 — like every new Doosan machine — are covered by an innovative 48-hour parts guarantee. The program guarantees that if a “machine-debilitating” part is needed, Doosan will deliver it directly to the end user within two business days or Doosan will pay for a replacement machine rental. The 48 Hour Parts Guarantee is subject to carrier delivery restrictions and/or governmental agency delays.
