Suwanee, Georgia-based Doosan Infracore North America LLC says it is launching its next-generation wheel loaders, the -7 Series, in the United States and Canada. The new series features redesigned cabs with what Doosan calls first-class comfort features, plus increased bucket capacities and new fuel-saving technologies.
Seven models of the new Doosan -7 Series wheel loaders, with standard bucket capacities between 3.7 and 7.6 cubic yards, are now available. Five additional Doosan models with bucket capacities between 2.6 and 3.3 cubic yards are planned to launch in early 2022. Wheel loaders launching in 2022 will include tool carrier iterations for two models.
“While we have made enhancements to our wheel loaders during the past 15 years, this is a significant milestone in the Doosan product,” says Aaron Kleingartner, dealer and product marketing manager. “The new -7 Series wheel loaders represent more than a decade of research and development, as well as incorporating feedback from our customers. The next generation of Doosan wheel loaders easily competes with any machine available today.”
Doosan says its new cab layout has relocated frequently used controls for what it calls easier, more intuitive use. All Doosan -7 Series wheel loaders have the same control setup, so operators will not need to readjust when moving from machine to machine.
For improved visibility from the cab, the total glass area is 14 percent larger than prior models. Large mirrors extend the operator’s view to the side and rear of the machine. A standard rearview camera provides an additional view of the machine’s surroundings and appears on the eight-inch Doosan Smart Touch display.
The heating and cooling system is redesigned from previous Doosan wheel loader generations, with new outlet locations designed to optimize air flow in the cab. Legroom is increased from prior generations, and additional in-cab storage has been added near the USB charging port.
Electric steering is available as an option in some -7 Series models. In models with this feature, the electronic joystick, which operators can customize to their sensitivity preference, is integrated into the left armrest.
“It’s become increasingly difficult for our customers to hire heavy equipment operators,” Kleingartner says. “Our investments in operator comfort provide an exceptional cab that makes it a pleasant experience for long days in the cab. We’re convinced that cabs today are among the most comfortable operating stations, which we hope will help our customers retain their operators.”
Bucket capacities on some models are 7 percent greater than prior models. Doosan models with this feature include the DL320-7, DL380-7, DL480-7 and DL580-7. The increased capacity has been designed to provide faster, easier loading in fewer cycles.
