New excavator and wheel loader working in company’s quarrying and recycled aggregate operations
ELLIOTTS (Cheltenham) Ltd, based in Bishops Cleeve, near Cheltenham, Gloucestershire, have purchased a new 40-tonne Doosan DX380LC-7 crawler excavator and a DL320-7 wheel loader for use in the company’s quarrying and recycled aggregate businesses.
The new machines were supplied by Kellands (Plant Sales) Ltd, based in Bridgwater, Somerset, the authorized Doosan dealers for the west and south of England.
Nick Elliott, managing director of Elliotts (Cheltenham) Ltd, said: ‘We have been buying Doosan machines for several years and the new DX380LC-7 crawler excavator and DL320-7 wheel loader are the latest.
‘We choose the Doosan brand because it is a guarantee of excellent, dependable equipment, backed by the expertise and fantastic service and support provided by Charlie Cook and the rest of the team at Kellands. We believe it is the best package available in our market.’
The new Doosan DX380LC-7 excavator is working at Perton Quarry, in Tarrington, Herefordshire, which is owned by the Elliotts group. The machine works at the face loading blasted material into a mobile crusher to produce 6F2 aggregate. The DX380LC-7 is also combined with a breaker to reduce any larger pieces of rock that come off the quarry face during blasting.
The mobile crusher moves between Perton Quarry and Elliotts’ main aggregate recycling operation based outside Cheltenham. Here it joins the new Doosan DL320-7 wheel loader to be part of the fleet of equipment used at the site, where construction waste is sorted and processed to produce 6F5 aggregate. The DL320-7 is used to load delivery lorries with the recycled aggregate.
The new Stage V excavator and wheel loader build on the very successful design of the previous Stage IV machines. They introduce major enhancements in operator comfort, machine controllability, productivity, uptime, and return on investment, with a strong focus on low fuel consumption, increased power, robustness, and versatility.
Part of the latest generation DX-7 range of Doosan excavators, the DX380LC-7 Is powered by the Scania DC09 Stage V-compliant diesel engine, providing 240kW of power at 1,800 rev/min. The excavator features Doosan’s innovative D-ECOPOWER technology, providing operators with higher productivity and lower fuel consumption per hour, as well as smoother controls.
The DX380LC-7 offers a digging depth of 8,165mm, a digging reach of 11,930mm, and a digging height of 10,940mm. The digging force over the bucket is 25.9 tonnes and the digging force over the arm is 16.0 tonnes.
With a standard bucket capacity of 3.3 cubic metres, the new DL320-7 wheel loader is part of Doosan’s new award-winning DL-7 wheel loader range. Power is provided by the new Doosan DL08V Stage V 6-cylinder engine, with an output of 202kW (271hp) at 1,800 rev/min. Increased bucket capacity provides increased productivity for a very wide range of material-handling applications.
The LIS (Load Isolation System) on the DL320-7 provides a smoother ride and greater comfort for the operator, as well as higher output 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.
The new EMCV (Electric Main Control Valve) joystick in the DL320-7 is fully integrated in the armrest in the cab, providing the operator with smoother and precise controllability of the lift arm and attachments. 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.
Nick Elliott concluded: ‘All our operators like the new machines, which provide advances in every area over the previous-generation machines. In particular, the operators like the redesigned cabs on both machines, which provide a very comfortable and safe environment to work in.
The new DX380LC-7 and DL320-7 are both factory-installed, as standard, with Doosan’s state-of-the-art DoosanCONNECT wireless fleet-monitoring system. It is available as a standard feature on all new Doosan excavators (from 14 tonnes and above), all new Doosan wheel loaders, and Doosan articulated dumptrucks.
