Doosan, excavator--Doosan Introduces 14-Ton DX140LCR Crawler Excavator

Company says its reduced tail swing makes it ideal for work on roadways and in tight quarters.

Doosan, West Fargo, N.D., has introduced the new DX140LCR crawler excavator with reduced tail swing, which the company says makes it ideal for working on roadways, railroad rights of way and in other tight quarters.

The tail-swing radius on the 14-ton DX140LCR is 4 feet 10 inches, which allows it to work on congested job sites, such as streets, highways and rail lines, without blocking traffic in adjacent lanes or tracks, according to the company. Reduced tail swing, it adds, minimizes the potential for damage when working close to buildings or walls.

A 12-foot-4-inch track length on the DX140LCR provides stability for digging and lifting operations. An optional dozer blade increases the machine’s lifting capacity even further, the company says.

The DX140LCR is powered by a best-in-class 99-horsepower, Tier 3-compliant Cummins diesel engine. It has an operating weight of 32,408 pounds with standard boom, arm and a 0.51-cubic-yard bucket.

The bucket breakout force is in excess of 23,000 pounds with the standard 9-foot-10-inch arm. The arm breakout force is in excess of 12,500 pounds. The lifting capacity over front at a 15-foot radius is 11,140 pounds, and drawbar pull is 27,558 pounds.

The DX140LCR also leads its weight class with a maximum digging depth of 19 feet 8 inches, according to Doosan. Maximum digging reach at ground level is 28 feet, and dump height is 23 feet 2 inches. Maximum travel speed is 3.1 mph in high range, while swing speed is 10.8 rpm, according to the company.

The DX140LCR has a standard auto-idle feature, which, the company says, reduces fuel consumption and noise. The auto-idle feature, which can be enabled at the operator’s discretion, automatically causes the engine to drop to idle if the excavator functions are not used for a period of about four seconds. The engine automatically returns to the pre-set throttle position when the operator moves a joystick or a travel function.

Depending on the application, the operator can choose between three working modes—power, standard or economy. Power mode uses 100 percent of available engine and hydraulic horsepower for heavy work and fast cycle times, the company says. Standard mode uses 85 percent of engine and hydraulic horsepower for general work and normal speed. Economy mode minimizes fuel consumption without any loss of performance, according to Doosan.

Engine service intervals are 500 hours, and the DX140LCR also shares the extended lubrication intervals of the entire Doosan excavator range. The water trap and engine oil filter are located in the hydraulic pump bay for easy access from the ground level.

The DX140LCR is covered by an 48-hour parts guarantee. The program guarantees that if a “machine-debilitating” part is needed, Doosan will deliver this part to the end user within two business days or will pay for a replacement machine rental.
