Doosan Infracore Construction Equipment will be showing its new crawler excavator and wheel loader at the 2013 World of Concrete Exhibition in Las Vegas, running from February 5 to 8.

The new DX140LC-3 Interim Tier 4 compliant crawler excavator on the stand at World of Concrete will be equipped with a coupler and hydraulic breaker. A plate compactor attachment which can also be mounted on the DX140LC-3 model will also be on show at the exhibition.

The excavator is powered by the reliable Doosan DL06 6-cylinder ‘common rail’ turbocharged diesel engine providing 74.5 kW (98 HP) of power at 1850 RPM.  The DL06 engine meets Interim Tier 4 emission regulations through the use of EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter) after-treatment technologies.

The new 12-14 tonne size class DX140LC-3 excavator offers a maximum digging depth of 5258 mm (17 ft 3 in) and a dump height of 5867 mm (19 ft 3 in).  Digging force over the bucket is 29156 kN (21,504 ft lb), while that over the arm is 19133 Nm (14,112 ft lb).  The swing torque on the DX140LC-3 excavator is 3330 kgf.m (24,086 ft lb).

Users can choose from Standard Mode for optimised fuel consumption and general working conditions, Power Mode for faster cycle times and heavy duty work requirements or Economy mode for reduced fuel consumption in reduced demand applications.

A new multi-function colour LCD monitor panel displays a variety of machine information, including operation history, flow rate control and filter/oil information.

The new DL200-3 wheel loader is also powered by the Doosan DL06 Interim Tier 4 diesel engine delivering 107 kW (143 HP) of power at 2100 RPM.  Like the DX140LC-3 excavator, the DL200-3 wheel loader features a new cab design offering better visibility thanks to a wider front glass section and an extended wiper blade area.

Now that the reservoir for the wiper water is located on the outside of the cab, space inside has been increased, providing more foot room.  The air conditioning system is regulated automatically by a temperature sensor.

With a bucket capacity of 2 cu m, the DL200-3 wheel loader is intended to meet a wide range of material-handling needs from loading and transporting granular material to industrial, mining and quarrying applications.

In common with all new generation Doosan wheel loaders, the DL200-3 model is equipped with load sensing controlled, variable hydraulic piston pumps, improving performance and reducing fuel consumption.  With load sensing, the hydraulic pumps receive a signal from the MCV (main control valve) informing how much oil is needed.  This helps to save on engine performance.

On the stand at World of Concrete, the DL200-3 wheel loader will be equipped with a coupler and pallet forks attachment.  As well as offering more standard features than other machines of its size on the market, there is an expanded choice of options for the DL200-3 wheel loader, including electric steering.

A larger opening angle for the side door makes it easier to service the machine.  Swing-out side doors provide easy access to the rear for cleaning the new one-block radiator.  Increased space in the engine compartment ensures that components such as filters, valves and batteries are within easy reach for service work. – TradeArabia News Service
