A Combination of Wheel  and Crawler Excavators Designed to Tackle Tough Jobs

Founded in 1896, Doosan is a strong, stable and global company with a long legacy in infrastructure support. Its history in equipment manufacturing began in 1937. Since 2005, Doosan has grown to become the fifth largest construction equipment manufacturer in the world. Many may be surprised to know that

Doosan has roots in construction and industrial products that go back more than 75 years. Today, Doosan Infracore Construction Equipment is the world’s fourth-largest manufacturer of mid- to large-sized crawler excavators.

Doosan and its heavy equipment dealers provide customers with a full line of dependable and durable excavators to choose from, including 13 crawler excavator models (three are available with super-long reach) and three wheel excavator models. Each excavator model has optimal fuel efficiency without compromising performance, reliability or durability. Two Doosan models, the DX140LCR-5 and DX235LCR-5, are designed with reduced tail swing for operation on confined jobsites. This is particularly helpful when operators are working on repairing or replacing infrastructure projects and there is limited room to operate. Wheel excavators are popular for road and bridge construction projects where they are capable of quickly driving on finished surfaces without disrupting them. Doosan crawler and wheel excavators are packed with power, boasting four unique power modes to help operators adapt to their work.

Doosan excavator customers can pair their machine with a variety of attachments to increase the machine’s versatility. Approved attachments include the following: breakers, buckets, hydraulic clamps, quick couplers and plate compactors. Operators can choose from four unique work modes. Two modes recalibrate machine power for digging or lifting, and two change the auxiliary hydraulic flow for specific types of attachments.

Product Spotlight: The Dash-5 Series

The newest Doosan crawler excavators (indicated by a dash-5 in the model name), including the DX140LC-5 through DX530LC-5 models, have been improved to increase performance, operator comfort, fuel efficiency, reliability and durability. An auto-shutdown feature was added to the excavators to help owners and operators save fuel during non-working conditions. Also included on the new models are: improved anti-skid plates; auto belt tensioner; fan and air cooling; battery upgrades; emergency engine stop; upgraded alternator; and a new front window design.

Advice

“It is important for operators to set up the crawler excavator in the proper work mode to optimize the machine to its best capabilities,” says Aaron Kleingartner, Doosan sales and marketing development manager. “For example, when the operator is digging or trenching, make sure the machine is set in the proper work mode to maximize the machine’s efficiency.”
