Doosan Infracore North America introduced its next-generation -7 Series crawler excavators in the United States and Canada. The initial launch includes four models, with more excavators to be announced in the coming months. The first models are the Doosan DX140LCR-7, DX225LC-7, DX255LC-7 and DX350LC-7.
The innovative Doosan -7 Series crawler excavators deliver the fuel efficiency and productivity that operators need to complete the work of today and prepare for the challenges tomorrow brings. With more comfort features, intelligent controls and smart machine functionality, operators can handle whatever comes their way.
“Doosan continues to build on the success of its existing excavator platform with more machine features that help our customers improve their productivity,” said Joel Escalante, product specialist. “We’ve enhanced the excavator cab with additional comfort features and now offer an all-around view monitor for even better operator visibility of the jobsite.”
Updates to the -7 Series excavators include a strengthened work group with reinforced castings and forged steel pivot points for withstanding high-impact work. A new Y-shaped seal at the end of the excavator’s arm provides better sealing to the bucket connection for more performance and durability.
Doosan added material to the excavator’s mainframe for higher performance and jobsite versatility. The excavator’s X-Chassis undercarriage further enhances durability and stability, while the track chain is sealed and self-lubricating for reduced maintenance. Cast-steel, heavy-duty sprockets are designed to stand up to challenging work environments, and track rollers and idlers are provided with oil level check plugs to maximize machine uptime.
All-Around View Monitoring (AVM) System
The optional 360-degree all-around view monitoring (AVM) camera system displays a full view of the machine’s surroundings, giving operators greater confidence when operating or positioning the machine in tight work areas. Five unique visual perspectives can be seen from the separate AVM monitor: top view, rear view, top+right view, rear+corner view and 3D view. The AVM camera system can be linked with optional ultrasonic detection sensors for an additional level of awareness of objects behind the machine.
Excavator Performance FeaturesO
perators can lift more weight with each cycle and complete their jobs faster with Doosan excavators designed and tested to maximize lifting capability. The standard counterweight provides improved machine stability when using heavier attachments. With an optimal swing radius, lift height and tilt position, operators can lift and place loads and dig with greater productivity.
The -7 Series crawler excavators (14 to 25 metric tons) offer an upgraded, cast push link with a reinforced lifting eye that delivers a 5-metric-ton lifting capacity. This design allows operators to remove an attachment and lift directly to fully utilize the machine’s lifting capacity.
New for the -7 Series is the fine swing function (14 to 25 metric tons). This function minimizes the shaking of a lifted object that occurs at the beginning or end of the swing movement. Operators can activate it for greater control and accuracy in certain lifting applications. This feature improves safety in pipe laying and maintains the bucket heap to maximize productivity.
Additionally, the new reduced tail swing counterweight design, along with the tighter front minimum swing radius on the reduced tail swing models, allows operators to work in confined areas – such as waste transfer stations and single-lane roadways – without sacrificing machine performance.
Doosan attachments are designed to match the excavator load ratings and hydraulic performance. A 16-gpm PTO (power take-off) pump improves the performance of various excavator attachments that require more hydraulic flow.
Innovative Technology
The DoosanCONNECT Telematics system comes standard on all -7 Series crawler excavators, making it easy for customers to remotely monitor and maintain their machines. DoosanCONNECT Telematics is an equipment diagnostic tool that monitors the health, location and productivity of Doosan construction equipment from a user-friendly mobile app and website.
The data pulled from the machines is uploaded automatically to the DoosanCONNECT online system using dual-mode communications (cellular and satellite) for maximum coverage. Doosan dealers can access the machine data and work with customers to resolve issues or make preventive maintenance recommendations to minimize downtime.
