Doosan's New Wheel Loaders Provide Fuel Savings
The Doosan DL250-5 and DL250TC-5 (tool carrier) wheel loaders offer improvements in fuel efficiency, operator comfort, serviceability, reliability and remote monitoring with Doosan Telematics. These models will replace the “dash-3” (interim Tier 4) models with a Tier 4-compliant Doosan DL06 diesel engine.
Choose between a Z-bar loader linkage for the DL250-5, and a parallel lift-arm design for the DL250TC-5. The Z-bar loader linkage is ideal for digging, heavy lifting and general construction tasks. The parallel lift-arm design helps keep items level while the wheel loader is moving. Limited-slip differentials are standard on both models. An auto-shutdown system saves valuable fuel during non-working conditions. Operators can configure the idle time before auto shutdown from 3 to 60 minutes. When enabled, the feature will shut down the wheel loader’s engine when the preset idle time is met.
Cab enhancements include an improved adjustable steering column to provide more leg room, ease of operation and more floor space. A new fuel consumption gauge informs operators of how much fuel the machine is using in real time. Updates to the keypad on the dashboard make it easier for operators to review, adjust settings and to clean and maintain it. Visibility within the cab and around the machine has been improved, too. Two rear LED lamps provide better views, especially when working at night.
Ease-of-maintenance updates include additional oil sampling ports improve preventive maintenance procedures and various fluid pressures are now viewable via the dash panel, allowing monitoring from the cab.
The DL250TC-5 has an optional quick coupler to easily change attachments, including buckets (general purpose, light material or multi-purpose) and pallet forks.
Tier 4 solution
The Doosan DL250-5 and DL250TC-5 engines use a high-pressure common-rail (HPCR) fuel delivery system and a cooled exhaust gas recirculation (CEGR) system. It utilizes a diesel oxidation catalyst (DOC) to reduce particulate matter (PM) and selective catalyst reduction (SCR) aftertreatment to reduce nitrogen oxides (NOx). Diesel exhaust fluid (DEF) is used with SCR technology.
