New Doosan products featured at World of Concrete

 For the first time at an international trade exhibition, Doosan showed the company’s new DX140LCR-7 Crawler Excavator  and  DL250-7 Wheel Loader together at World of Concrete, held from 18-20 January 2022 at the Las Vegas Convention Centre in Nevada in the USA.

New DX140LCR-7 Crawler Excavator

Part of Doosan’s new generation DX-7 family of medium-sized Stage V compliant crawler excavators, the 15.6 tonne DX140LCR-7 is a reduced tail swing model, allowing operators greater flexibility where space is a premium without sacrificing performance. The DX140LCR-7 also offers a new counterweight design that provides enhanced service accessibility.

The DX140LCR-7 is powered by the Doosan D34 4-cylinder Stage V diesel engine providing 86 kW (115 HP) of power at 2000 RPM. The enhanced fuel efficiency of the engine in combination with a new hydraulic main valve and the new generation SPC3 Smart Power Controls, provides increased fuel saving compared to the previous generation machine.

The state-of-the-art cab on the DX140LCR-7 excels in terms of spaciousness and ergonomics, taking operator comfort and ease of operation to new levels. As well as a new high quality seat, the enhanced cab offers more features as standard than other machines on the market, ensuring super controllability and high precision in all applications.

The DX140LCR-7 excavator utilises a new smart hydraulic system that offers an improvement of around 30% in attachment work, compared to the previous generation model. There is a new Tiltrotator Mode on the control panel in the new excavator, which can be selected to ensure an optimized hydraulic flow and helps to maximize the accuracy of tiltrotator work by eliminating back pressure.

Another standard new feature is the Fine Swing function which minimizes the shaking that a lifted object undergoes at the start or stop of a swing movement with the excavator, to increase the safety of nearby workers and to prevent damage caused by the object falling from the excavator. The new excavator also incorporates as standard a new lifting eye that forms part of the casting for the push link for the bucket attachment at the end of the arm.

New DL250-7 Wheel Loader

With a standard bucket capacity of 2.5 m3, the new DL250-7 wheel loader is part of Doosan’s new award-winning ‘DL-7’ wheel loader range. Like all DL-7 models, the DL250-7 introduces a next generation design, incorporating a powerful new Stage V compliant engine and providing higher productivity, increased fuel efficiency and a low cost of ownership, coupled with a superb environment and experience for the operator. Power is provided by the new Doosan DL06V Stage V 6-cylinder engine on the DL250-7 wheel loader, with an output of 128 kW (172 HP).

The LIS (Load Isolation System) on the DL250-7 provides a smoother ride and higher comfort for the operator, as well as higher productivity due to improved stability when the wheel loader is moving. The lift arm is cushioned by a hydro-pneumatic accumulator linked to the lift hydraulic system, acting as a shock absorber. The benefits include reduced cycle times, higher performance and better fuel efficiency while carrying out load and carry applications. Improvements have been made throughout the powertrain, to provide operators with an 11% increase in travel speeds up to a maximum of 40 km/h.

The new cab offers a greatly improved field of vision for the operator, with blind spots around the cab minimized and a 14% larger glass window area compared to the previous DL-5 model.

Inside the cab, the new wheel loader offers significantly enhanced operating comfort, an enhanced steering system and advanced electronic controls. Using the new Doosan Smart Key system on the control panel in the cab, the operator can start the machine using a keyless device, helping to prevent machine theft. The Smart Key system provides remote door control, door lock and unlock, door release, searching and other functions.

The new EMCV (Electric Main Control Valve) joystick fully integrated in the armrest is another standard feature in the cab, providing the operator with smoother and precise controllability of the lift arm and attachments on the wheel loader. Features available via the EMCV system include Automatic Return-to-Dig, Bucket Tilt Kick-out and the Bucket crowd stop position and shock prevention for higher operator comfort.

DoosanCONNECT Telematics System

The new DX140LCR-7 and DL250-7 are both factory-installed as standard with Doosan’s state-of-the-art DoosanCONNECT wireless fleet monitoring system. The DoosanCONNECT system offers a web-based fleet management solution which is very useful for monitoring the performance and security of machines and promoting preventative maintenance.

It is available as a standard feature on all new Doosan excavators (from 14 tonne), all new Doosan wheel loaders and Doosan articulated dump trucks.
