Doosan launches the new DL420 articulated wheel loader with a larger, more powerful diesel engine than the model DL400, which it replaces. With a bucket capacity of 5.2 cubic yards, the DL420 is designed to take on a wide range of material handling tasks from loading and transporting granular material to industrial, mining and quarrying applications.

“The DL420 is sized to fit a large variety of applications, from highway construction to sand and gravel operations,” says Chad Ellis, Doosan heavy equipment product specialist. “It is user-friendly and easy to operate, and has a quiet, comfortable cab with plenty of room for any size operator.”

The 49,163-pound DL420 is powered by a 659-cubic-inch, 6-cylinder turbocharged Cummins QSM11 electronically controlled engine with high pressure unit injector system and a state-of-the-art combustion system. Emissions are well below Tier-3 regulatory limits.

The DL420 features a full powershift transmission with manual and automatic modes. Standard limited slip differentials on both the front and rear axles assure positive traction in wet or soft conditions. It also offers a new integrated monitoring system that displays information about the loader's engine and transmission, including service intervals for each filter and the engine oil.

“The integrated monitoring system provides service fault codes to the operator without the need to hook up a PC,” says Ellis. “Codes can then be reported to the dealer's service technician through standard GPS, saving diagnostic time and reducing expense. In addition, the integrated monitoring system allows the transmission to be tuned by the operator without the assistance of a mechanic. The system is standard on the DL420.”
