Doosan fleet at Carnsew Quarry in Cornwall
A fleet of Doosan machines supplied by Duo Operations, part of Duo Group Holdings Limited, is central to the smooth running of Carnsew Quarry in Cornwall in England. Along with West of England Quarry, Carnsew Quarry is one of two locations in the Colas Cornwall Quarries division. Both are hard rock quarries, providing a wide range of quarry products and asphalt to the local market by road, and further afield by road and sea.
The Doosan line up includes two DA40-5 articulated dump trucks, which support the haulage between the primary and secondary crushing operations. Working alongside those machines are Doosan DL450-5 and DL550-5 wheel loaders used to stockpile quarry products, plus load the ADTs and road trucks delivering to sites around the area. The Doosan fleet is completed by a pair of Doosan DX380LC-5 crawler excavators that load the secondary crusher and assist with breaking.
All the Doosan equipment operating at Carnsew Quarry are fitted with DoosanConnect advanced state-of-the-art telematics (as standard). Using the data provided by DoosanConnect, Duo Operations reports directly to Colas on a monthly basis. This supplies Colas with information on fuel efficiencies, fuel levels, fault codes, warnings and for the ADTs, it shows load counts. All of this information is useful to Colas and enables the company to plan and maximise the profitability at Carnsew Quarry. It also gives Colas a good indication of the cost per tonne. Duo Operations also provides Colas with details on any operator faults and to offer advice and feedback to prevent any future maintenance issues.
