Doosan launches new line of next-generation mini excavators in North America
Doosan Infracore North America has launched its new line of next-generation -7 Series mini excavators in the United States and Canada. The initial launch includes four models, with more mini excavators to come.
These new mini excavators are designed and manufactured by Doosan. They are equipped with a family of products, including Doosan engines and diagnostics. The first four excavator models include the zero tail swing DX27Z-7, DX35Z-7, and DX50Z-7, as well as the reduced tail swing DX55R-7. The new DX27Z-7 expands the Doosan mini excavator lineup with a model that appeals to customers who need a smaller machine.
"This is a significant milestone for Doosan as we bring an all-new lineup of mini excavators to North America," says Aaron Kleingartner, Doosan Infracore North America product and dealer marketing manager. "A few years ago, we expanded our mini excavator offering and the response from our dealers and customers was very positive. Now we can provide a Doosan-designed family of mini excavators from 2.7 metric tons up to approximately 9.0 metric tons to match our customers' needs."
Performance features of the -7 mini excavator series
The Doosan -7 Series mini excavators come with a newly designed platform to improve structural durability. The redesigned models increase productivity and are able to perform multiple tasks at once.
Customers can get more productivity from the -7 Series mini excavators thanks to an increase in counterweight. Integrated into the excavator design, the additional counterweight enhances the excavator's structural durability while enabling offset digging without the need to reposition the machine. Lift-over-side capacity is also enhanced because of the machines' counterweight design. Doosan -7 Series mini excavators deliver impressive lifting capacity for moving and placing pipes as well as lifting boulders and hardscape materials.
A long arm design is available as an option for specific new models. The longer arm provides operators with greater reach, dump height, and dig depth, and operators don't need to reposition the machine as often. Some customers prefer to upgrade to a long arm design and avoid purchasing a larger machine for greater dig depth within the same size of excavator.
Mini excavators are versatile machines and the new -7 Series models from Doosan maintain that standard. Each new model is available with attachments, including buckets, a quick coupler, and a thumb. The quick coupler significantly reduces the time it takes to switch attachments, which can impact operator productivity and ensure the correct bucket is paired with the digging requirements. Excavator owners can also operate attachments like augers, hydraulic breakers, plate compactors, rippers, and grapples.
"All of our -7 Series mini excavators have a quick-coupler-ready design with auxiliary hydraulics installed to the base of the excavator arm," Kleingartner says. "Customers won't need additional accessories to install a quick coupler to the mini excavator. We also offer adjustable auxiliary hydraulic flow which optimizes the response of hydraulic attachments, including thumbs, hydraulic breakers, and augers."
Flush-face couplers on the end of the hydraulic hoses allow for quick, easy connections when using hydraulic-powered attachments.
Customers can add an optional second set of hydraulics when they need to operate multifunctional attachments that require additional hydraulic flow. For example, secondary auxiliary hydraulics are ideal for using tiltrotator accessories with mini excavators.
Doosan -7 Series mini excavators come standard with enclosed cabs with heat and air conditioning and multiple vents throughout the cab. This is designed to help keep operators comfortable and minimize the dirt and debris inside the machine. Heated seats and fold-up foot pedals are also available options. An open canopy is available as an option on -7 Series mini excavators and comes with a Rollover Protective Structure (ROPS).
The -7 Series mini excavators are designed with full glass, framed doors for a clear view of the area alongside the machine. This can be important for the operator when working in tight areas or going through narrow openings. A new rearview camera is available as an option for increased visibility behind the excavator. Note, this option requires the machine to be configured with the 5.7-inch LCD monitor. Standard LED lamps help to illuminate the work area and ensure operators can see the excavator workgroup, particularly the attachment, when working in low-light areas.
Joysticks in Doosan -7 Series mini excavators are now similar to those installed in large Doosan crawlers and wheel excavators. This makes it easy for operators to move from a mini excavator to a larger machine or vice versa.
A swing-open tailgate and side-access hood provide easy access to the excavator's engine and pump package, valve bank, cooling system, and hydraulic system. Everyday maintenance items like filters, fluids, air cleaner, and battery are also easy to reach. A centralized grease bank makes it simple for operators to properly add grease to the machine. Additional maintenance features include the following:
- Battery disconnect switch
- Colour-coded and labelled wiring and hydraulic hoses
Available for the first time on Doosan mini excavators is a standard telematics system. The DoosanCONNECT telematics system comes with every Doosan -7 Series mini excavator model, making it easy for owners to remotely monitor and maintain their machine. This is the same system that is available for larger Doosan construction equipment. Owners can monitor their entire Doosan fleet through a smartphone app or web browser.
The system can alert owners when a machine is moved outside of an area, which helps to protect against theft. Another benefit is the system can notify owners if a machine is being operated during an unauthorized time.
The DX27Z-7 mini excavator
The DX27Z-7 mini excavator is a new size class for the North American lineup. It includes features brand new to the Doosan mini excavator line. The new rearview camera allows an operator to navigate a full 360 degrees on job sites. Other features include a 3-foot 7-inch standard-thumb-ready arm and an 11.8-inch rubber track undercarriage. A machine of this stature – just 60 inches wide – can fit in many confined job sites. The DoosanCONNECT Telematics system comes standard, making it easy to remotely monitor and maintain the machine. Standard attachments for the DX27Z-7 mini excavator include a bucket, quick coupler, and a thumb.
The DX35Z-7 mini excavator
With an all-new design, the 24.7-hp DX35Z-7 mini excavator is ready to work where other machines can't. This new mini excavator features a zero tail swing design with a rounded shape, making it easier than ever to navigate on confined or crowded work sites. It delivers superior lifting capacity and digging force, supported by a large auxiliary hydraulic flow when using attachments. Other new features include a Doosan diesel engine, a wider cabin for added comfort, and a high luminous LED lamp for improved visibility in low-light conditions. An enclosed cab, powerful new heating and cooling system, 5.7-inch, full-color LCD monitor, and DoosanCONNECT telematics are standard.
The DX50Z-7 mini excavator
The new 48.8-hp Doosan DX50Z-7 mini excavator is part of the 5-metric-ton size class. Its zero tail swing design makes it a popular choice for customers working in confined spaces on construction job sites or landscaping projects. A standard enclosed cab with heat and air conditioning will keep operators working comfortably throughout the day. Customers can upgrade to a steel track option for use in job site conditions that may otherwise damage rubber tracks. Standard attachments for the DX50Z-7 mini excavator include a bucket, quick coupler, and a thumb.
The DX55R-7 mini excavator
The DX55R-7 mini excavator is a new offering in the Doosan lineup. Positioned between the DX50Z-7 and DX62R, the reduced tail swing excavator is part of the popular 5-metric-ton size class. Standard features of the Doosan DX55R-7 mini excavator include an enclosed cab with heat and air conditioning, heated adjustable seat, 5.7-inch, full-color LCD monitor, Bluetooth audio, auxiliary hydraulics, and quick coupler piping. Options include an 8-inch LCD monitor, second auxiliary hydraulics, rearview camera, steel tracks, and rotating beacon. Approved attachments from Doosan for the DX55R-7 include buckets, a quick coupler, and a thumb.
