The former Comrie colliery site is recognised as the largest area of post-industrial dereliction in West Fife, with more than100 hectares of countryside unfit for any conventional countryside use.
The Doosan DA40 ADT has an increased body capacity of 24.4m³, and the payload has been boosted to 40 tonnes without tailgate, an increase of more than 15% over the payload of Doosan’s previous MT41 model.
LES director Dean Devine said: “In one of the tests we carried out, the fuel efficiency of the DA40 was compared to that of an equivalent model from another manufacturer and we found that the DA40 used up to 10 litres per hour less fuel on the applications we typically carry out.
“In another test that we conducted in the thick wet clay that we have at our project in Tadcaster in Yorkshire, the DA40 greatly outperformed other ADTs on the site in terms of its ability to drive and manoeuvre in the heavy conditions.”
He added: “The DA40 also scores very highly in terms of operator comfort. We have had a number of different operators driving the new ADTs and all of them agreed that it was the comfiest cab they had ever been in.”
The DA40 has a six-cylinder Scania DC13 Stage IIIB compliant diesel engine with a gross power output of 368 kW (500 HP) at 2100 rpm, offering a 10% increase in engine power compared to the previous Doosan MT41 model. The increased engine power is combined with SCR technology to further lower fuel consumption.
Also contributing to the overall 8% reduction in fuel consumption is the new ZF transmission offering eight forward and four reverse speeds. The new transmission improves the transfer of power from the engine to the wheels for outstanding traction. To withstand the increased power, the driveline dimensions and cooling capacity of the truck have been increased.
The Doosan DA40 trucks were supplied by Filtermech Plant Sales, the doosan dealer for Yorkshire, also based in Wakefield.
