Loughran Rock Industries has bought the first 70tonne Doosan DX700LC crawler excavator in the UK and Ireland.
The first 70tonne Doosan DX700LC crawler excavator in the UK and Ireland has been sold to Loughran Rock Industries in Armagh, Northern Ireland.  

Loughran Rock Industries supplies a range of rock products including concrete aggregates, high PSV materials, rail ballast, drainage materials, sub-bases, rock armour and surface dressing chippings.   

Sold by Northern Excavators, based at Hillsborough in Northern Ireland, the arrival of the machine means Loughran Rock has been able to replace two 50tonne excavators while increasing production levels to the required levels. In addition, there are deep beds of shale at the quarry which can now be excavated using the larger DX700LC excavator.

Company owner, Patrick Loughran, said: “The new DX700LC excavator is the largest in the range of Doosan crawler excavators and is designed and built to meet the needs of heavy quarrying and other similar applications. The gritstone we produce is a quality product that is pretty abrasive to deal with.

“Once we’ve drilled and blasted out the rock, the DX700LC excavator continuously loads the gritstone into two 60tonne rigid dump trucks which take it to our crusher plant for use mainly in the production of concrete and asphalt.”

Over the last 17 years, Loughran has purchased a wide selection of Doosan products from Solar range excavators and Mega range wheeled loaders to the more recent DX140LC excavator and DL400 wheel loader products.

The DX700LC’s long carriage (LC) design, in combination with the undercarriage expanded to its maximum working width of 4,000mm, is said to offer optimum stability and safety in all kinds of digging, lifting and loading applications.  

Equipped with the EU-approved 2,900mm arm, the DX700LC offers a maximum digging depth of 7,765mm; a maximum digging height of 12,080mm; a maximum digging reach of 12,715mm and a dump height of 8,180mm. The minimum swing radius is 4,090mm.

Digging force over the bucket is 33.3tonnes, while that over the arm is 27tonnes. The power boost feature increases both forces by about 9%.
