Doosan’s DX300LC-5 excavator for Gordon Robertson Plant Hire
First publishedin Aggregates Business Europe
Gordon Robertson Plant Hire’s introduction of a new Doosan DX300LC-5 30 tonne crawler excavator at the company’s Caithness stone quarry at Barrock near Thurso in Scotland is said to have led to the site producing 50% more aggregate.
Delivered just three weeks after placing the order for the machine with Balgownie Ltd, the local authorised Doosan and Bobcat dealer, the new DX300LC-5 excavator is also said to have reduced the quarry’s fuel costs.
The new DX300LC-5 was said to be purchased due to the excellent performance of Doosan 14 tonne and 6 tonne machines that have been part of the fleet at Gordon Robertson over the last six years.
Company owner, Gordon Robertson, said: “The fact that Balgownie and Doosan could deliver me the DX300LC-5 in just 3 weeks from placing the order was key. We needed the machine quickly to work with a new 3.5 tonne hydraulic breaker we had purchased for breaking out rock at the quarry.”
The new DX300LC-5 is powered by the Scania DC9 5-cylinder diesel engine, with an output of 202kW of power at 1800 rpm, providing a claimed huge 27% increase in engine power and a claimed massive 30% boost in torque over the previous LC-3 model. The engine meets Stage IV emission regulations without need of a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies.
As well as the Scania engine, new innovative and exclusive features have been introduced, leading to claimed significant reductions in fuel consumption compared to the Stage IIIB machine. Among these features, is the new ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel.
