Doosan Infracore North America, LLC, is launching its next-generation wheel loaders, the -7 Series, in the U.S. and Canada. All-new redesigned cabs with first-class comfort features, increased bucket capacities and new, fuel-saving technologies are highlights of this next generation of Doosanwheel loaders.
Seven models of the new Doosan -7 Series wheel loaders, with standard bucket capacities between 3.7 and 7.6 cubic yards, are available now. 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 the popular 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.”
New Look and New Cabs
A new, award-winning exterior design is likely the first feature customers will notice about the Doosan -7 Series wheel loaders. The completely redesigned, more comfortable cab is a close second.
· For improved visibility from the cab, the total glass area is 14 perent larger than prior models and a full glass door improves visibility on the left side. Large mirrors extend the operator’s view to the side and rear of the machine.
“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 for select models are 7 percent greater than prior models. These select Doosan models include the DL320-7, DL380-7, DL480-7 and DL580-7. The increased capacity is designed for faster loading.
· To enable these greater capacities, these beefed-up models feature stronger, larger axles and a strengthened box frame. Large center bearings and self-centering, double-tapered roller bearings distribute vertical and horizontal loads over a larger area. The bearings have dust seals and covers and are vented to prevent grease overfill.
· The new axles offer better braking capacity to extend the lifetime of the brake discs. Other improvements that enhance durability include a new radiator with fin spacing that is 40% wider than previous generations. This wider spacing makes the radiator less prone to clogging and easier to clear of dirt, dust and other large debris.
· A standard reversible fan, adjustable from the Doosan Smart Touch screen, further improves cooling system performance. The fan is hydraulically driven with variable speeds that are proportional to the operating temperature. It easily folds out of the way for cleaning the radiator. This can be particularly useful in applications like agriculture and forestry.
· An automatic lubrication system is a new factory option for Doosan -7 Series wheel loaders, and it includes full warranty coverage. The system delivers grease at the middle of the pins and bushings for better distribution.
Loaded With Smart Technologies
Doosan -7 Series wheel loaders are designed with standard technology features that owners and operators can use to make meaningful improvements to the productivity of their operations. Technologies standard on Doosan -7 Series wheel loaders include:
· DoosanCONNECT® telematics makes it easy for owners to monitor their Doosan fleet and manage maintenance to reduce operating costs. Using a smartphone, tablet or computer, owners can check machine location, operating hours, fuel usage, engine idle versus work time, error codes, engine and hydraulic oil temperature and various other data points.
· Situation Awareness Technology automatically monitors the machine’s activity and adjusts the wheel loader engine’s output to match real-time requirements of the hydraulic system and drivetrain.
· The Doosan Smart Guidance System analyzes operator driving habits and provides tips during operation on the Doosan Smart Touch display to improve their efficiency.
· An improved Load Isolation System improves wheel loader stability while moving, which can reduce cycle times, increase productivity and boost fuel efficiency.
· The new Doosan Smart Load weighing system tells the operator the weight of material in the bucket. All menus and settings are integrated into the Doosan Smart Touch screen.
· The Doosan Smart Key is a key fob that can unlock the cab and allows the push-button engine to start.
“We offer a wide range of wheel loader models to meet our customers’ needs,” Kleingartner says. “Our 12-model lineup provides customers a variety of horsepower and capacity offerings to best match their applications. Customers operate Doosan wheel loaders in agriculture, construction, recycling, mining, snow removal and forestry applications. Across these applications, customers can expect Doosan wheel loaders to be productive and durable.”
