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 hp turbocharged Isuzu diesel engine, the DX700LC has an operating weight of 72 099 kg with standard boom and arm, 90 cm double grouser shoes and 3,3 m3 bucket. Optional buckets range in size from 2,5 m3 to 4,5 m3. The DX700LC offers a new power mode control system that provides optimum power and efficiency under all operating conditions. 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. 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. Doosan Infracore Construction Equipment America will be exhibiting at CONEXPO-CON/AGG 2011. |
