- Company & Industry News
Doosan Infracore Construction Equipment has launched the new Stage IIIB compliant DX300LC-3 crawler excavator. Because this new generation model have been designed to exceed customer requirements for quality, productivity, fuel saving, controllability, comfort, reliability, durability and reduced overall costs, it demonstrates why purchasing a Doosan excavator is always an excellent investment, both in the short term and the long term. As a result, the new DX300LC-3 excavator is a dependable, high performance machine, that will increase profits and return on investment for a host of customers including civil engineers, contractors, rental companies and aggregate producers, engaged in all types of earthmoving, road building, demolition, quarrying and material handling applications.
- Unmatched operator comfort with unique jog/shuttle control
- Very high performance and fuel efficiency
- Outstanding drawbar pull and digging forces
- Many more features as standard
- Enhanced controllability and serviceability
Increased Operator Comfort
The new ROPS and OPG certified cab offers more space (+6%) for the operator and several convenient features, including direct control through the joysticks, which have new proportional thumb wheel switches and integrated buttons to provide precise, proportional control of attachments.
A new 7-inch colour high quality visual control console offers an attractive display and excellent functionality. All functions can be controlled both from the instrument panel as well as via a new jog/shuttle control next to the joystick, a feature exclusive to Doosan excavators. A new function allowing the operator to select and set engine speed, hydraulic flow and pressure for attachments, with several preset positions, is a standard feature.
A new high-quality, heated air suspension seat reduces operator fatigue, while a new cab suspension system helps to cut vibration by 20% and reduce the sound level in the cab to 71 dBA.
The cab is pressurised to prevent particles from entering the cab. Lighting capability has been increased 100% to facilitate working at night. A side camera is available as a safety option. Other features include fully automatic climate control, a USB port to play music and videos, and more storage compartments for paperwork and other items.
Higher Power and Fuel Efficiency
The DX300LC-3 excavator is powered by the Doosan DL08K ‘common rail’ 6-cylinder turbocharged diesel engine meeting Stage IIIB emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies. At 159 kW, the Doosan DL08K engine in the DX300LC-3 excavator delivers 2% more power at a lower speed of 1800 rpm than the existing DX300LC Stage IIIA model. Factory tests show a 5 to 10% reduction in fuel consumption, depending on the operating mode selected and the work being done.
A new ECO Gauge on the control panel helps the operator to lower fuel consumption by providing real time monitoring of fuel rate and actual engine-percent load. Two new operating modes (P+ mode: Power Plus and L: Lifting) improve controllability and efficiency.
Higher Workload Output
Workload/hour outputs have increased by an average of 6% across the different power modes in the DX300LC-3. A new travel device has increased the maximum travel speed to 5.3 km/h, while the drawbar pull is increased by 4% to 26,200 kg and lifting capacities have been increased by 6%.
New hydraulic pumps and valves increase hydraulic flow by up to 11% and pressure (350-370 bar) to boost front, travel and power functions as well as increase lifting capabilities and reduce cycle times. Overall, the new hydraulic system improves the productivity of the machine through highly responsive controls.
Lower Total Cost of Ownership
The DX300LC-3 excavator has a more robust undercarriage with increased durability in the boom and arm, extending mean time before failure by over 30%.
The engine bonnet is split into four parts to improve serviceability, whilst components such as filters, valves and batteries are all within easy reach for service work. Cooling capacity has been increased by 10 to 15% compared to the previous generation machine.
As well as offering more standard features than other excavators of its type on the market, there is a greatly expanded choice of options, including a floating boom system for easy levelling and finishing work. Options for heavy duty applications include dual pump flow providing extra power for high flow attachments; a straight travel pedal; an oil-washed air cleaner; and additional protection such as dual track guards and full length track guards. The DX300LC-3 is available with either standard or narrow tracks as well as monobloc or articulated front working equipment.
