30-tonne crawler has “tremendous impact” at Caithness quarry


A Caithness firm has snapped up a Doosan DX300LC-5 30 tonne crawler excavator for use at the company’s stone quarry at Barrock near Thurso.

Gordon Robertson Plant Hire purchased the machine from Balgownie after having positive experiences with other Doosan models and it has reportedly already made a “tremendous impact” by increasing productivity and reducing fuel costs.

Company owner, Gordon Robertson explained, “Our machines take part in all types of projects, including land drainage work in agriculture and housebuilding and I have been very impressed by the performance and durability of all of the Doosan excavators since I purchased the first 6-tonner in 2010. All of our drivers are delighted with the new DX300LC-5 excavator and have remarked how comfortable the cab is and how smooth the machine is to operate.

“The fact that Balgownie and Doosan could deliver me the DX300LC-5 in just three weeks from placing the order was also a key feature. 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 and we are now producing 50% more aggregate at the quarry since the new Doosan excavator arrived.”

The DX300LC-5 is powered by the Scania DC9 5-cylinder diesel engine, with an output of 202 kW of power at 1800 rpm, providing a 27% increase in engine power and a 30% boost in torque over the previous LC-3 model.

New features on the machine include a ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily directly from the control panel, the new Auto Shut-Off which provides an automatic shut down for the engine after a pre-set time when the machine has been idle and a SPC (Smart Power Control) to optimise the balance between the pumps’ output and the diesel engine.
