Doosan DX700LC for Loughran Rock Industries

Doosan DX700LC excavator

Northern Ireland quarry firm purchases first 70-tonne Doosan excavator in UK & Ireland

THE first Doosan DX700LC 70-tonne crawler excavator in the UK and Ireland has been sold by Northern Excavators, based in Hillsborough, Northern Ireland, to Armagh-based Loughran Rock Industries.

The new machine has replaced two 50-tonne excavators yet is still able to meet increased production levels at the quarry. In addition, deep beds of shale at the site can now be excavated using the larger DX700LC.


The new machine 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.

Company owner Patrick Loughran said: ‘The gritstone we produce is a quality product that is pretty abrasive to deal with, so you need a machine with the power and durability offered by the DX700LC to load the stone day in, day out to meet productivity targets. Once we’ve drilled and blasted out the rock, the DX700LC excavator continuously loads the gritstone into two 60-tonne rigid dumptrucks which take it to our crushing plant.’

Equipped with a 2.9m arm, the DX700LC offers a maximum digging depth of 7.76m, a maximum digging height of 12.08m, a maximum digging reach of 12.71m and a dump height of 8.18m. The digging force over the bucket is 33.3 tonnes, while over the arm it is 27.0 tonnes. The machine’s power boost feature increases both figures by around 9%.

The new DX700LC excavator is the latest in a long line of Doosan products purchased by Loughran Rock Industries since 1995. This includes products from the Solar excavator range and Mega wheel loader range, to the more recent DX140LC excavator and DL400 wheel loader.
