Thomas Armstrong (Aggregates) Ltd has recently purchased a state-of-the-art long reach excavator and system to support the business at their own Cardewmires Sand Gravel Quarry in Dalston, Carlisle.

‍

Acquired in 2014, the large, long-established quarry has been producing high quality sand gravel since the early 1980s. The new Hitachi 520 360 long reach excavator, which sits on a pontoon, is designed to extract the gravel from underneath the water using a controlled plotting system. This gravel is then loaded onto a barge and returned to the shoreline, which is then tipped into the dock.

Thomas Armstrong Group continues to expand and invest in the latest manufacturing processes, machinery, and people to remain competitive and to ensure we keep in line with the latest technological advances. This recent investment will ensure the company can continue to meet the customer’s demands and therefore it’s future success.
