Doosan adds 72.1 metric ton DX700LC to top of crawler excavator range ATLANTA, August 2010 — Doosan introduces its largest crawler excavator, the DX700LC, designed for heavy-duty mining and quarrying applications as well as major infrastructure construction projects and mass excavation work. Powered by a 463-horsepower turbocharged Isuzu diesel engine, the DX700LC has an operating weight of 158,953 pounds with standard boom and arm, 35.4-inch double grouser shoes and 4.32-cubic-yard bucket. Optional buckets range in size from 3.27 to 5.89 cubic yards. Bucket breakout force is 78,485 pounds with the standard bucket, while arm breakout force is 64,595 pounds. Maximum digging reach is 42 feet 7 inches at ground level and maximum digging depth is 27 feet 7 inches. Dump height is 27 feet 4 inches. The long carriage (LC) design of the DX700LC, along with the 13-foot-11-inch width of the fully expanded undercarriage, offers optimum stability and safety in all kinds of digging, lifting and loading applications. Thanks to high swing torque of 48,369 pounds, the DX700LC works efficiently on slopes. Swing speed is 7.1 rpm. Fuel-efficient Tier 3 engine The 6-cylinder “common rail” Isuzu AH-6WG1X engine features a high-pressure fuel injection system that improves combustion efficiency while reducing particulate matter. At the same time, exhaust gas recirculation (EGR) lowers the combustion temperature, reducing nitrogen oxide emissions on the Tier 3 compliant engine. An electronic power optimizing system (e-EPOS), connected to the engine’s electronic control via a data transfer link, harmonizes the operation of the engine and the hydraulic system, further minimizing fuel consumption. The DX700LC offers a new power mode control system that provides optimum power and efficiency under all operating conditions. The four modes include:
The unit’s positive control piston pump and open center valve enable fine metering of hydraulic flow for smooth, precise control of machine functions. Flow regeneration conserves energy and enables increased boom and arm cycles. Both the boom and arm cylinders are cushioned to provide smooth end-of-stroke operation while the holding system prevents attachments from falling when the controls are in the neutral position. An automatic 2-speed travel system controls travel speed and tractive force. In high range, maximum travel speed is 2.9 mph. Drawbar pull is 107,806 pounds. Operator comfort As with all Doosan excavators, the operator’s cab is spacious, quiet and comfortable, with ergonomic controls and instrumentation. Joystick control stands raise and lower with the suspension seat while the seat itself slides forward and back to accommodate any operator. In addition, the DX700LC is designed to keep machine noise levels as low as possible to reduce operator fatigue and make it easier for bystanders to communicate. The noise level at the operator’s ear is 76 dBA while the noise level for bystanders is a very low 108 dBA. Ease of maintenance The DX700LC shares the extended lubrication intervals of the entire Doosan excavator range, including 500-hour engine service intervals. Other ease-of-maintenance features include:
The DX700LC — like every Doosan machine — is covered by an innovative 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 Doosan will pay for a replacement machine rental. In addition, Doosan is now offering new financing and leasing options through Doosan Global Finance. ###
