5 New wheel loaders boast improved fuel efficiency

Winter 2015

Five new wheel loaders offer improvements in fuel efficiency, operator comfort, serviceability and remote monitoring with the Doosan Telematics system. The models may be configured with an optional high-lift lift arm for additional dump height when loading trucks.

Enhanced cab features include an improved adjustable steering column to provide more leg room, ease of operation of more floor space. Also inside the cab, a new fuel consumption gauge informs operators 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. Overall, visibility within the cab and around the machine has been improved too.

Selectable engine power modes

Three selectable engine power modes are available on the new models — Economy, Standard and Power — to better balance fuel consumption and machine power with working conditions.

• Economy mode: reduces fuel consumption for low-demand applications and slows down machine movement for conditions that require extra precision
• Standard mode: balances fuel consumption for everyday digging, grading and lifting tasks
• Power mode: provides superior power and performance for tough digging conditions and truck loading tasks

Tier 4 solution

The new wheel loaders are powered by Tier 4-compliant Scania diesel engines and have been optimized for use with a high-pressure common-rail fuel delivery system, cooled exhaust gas recirculation system and variable geometry turbocharger (VGT). A selective catalyst reduction with diesel exhaust fluid and a diesel oxidation catalyst are included. Other new features include an exhaust brake and a mass airflow sensor that allows the electronic control unit to improve the management of airflow from the VGT, and optimizes fuel delivery to the combustion chamber based on engine air intake volume and rpm.

NEW DL300-5, DL350-5, DL420-5, DL450-5 and DL550-5 wheel loaders

KEY FEATURES

• Auto-shutdown system: helps reduce fuel consumption
• New air cleaner: offers longer replacement intervals
• Oil sampling ports: improves preventive maintenance procedures
• Fluid pressure diagnostics: on-board monitoring from the cab
• Improved lighting: enhances lighting with new rear LED lamps
• Axle cooler option: (DL420-5 and larger) helps axle run in lower temperatures in severe applications
• Auto greasing system option: replaces daily greasing, extends bearing bushing life
• The optional auto greasing system will grease the correct amount when needed to avoid over-greasing and under-greasing — a considerable timesaver for fleet owners.
