Scottish quarry firm takes first Cat 972M XE

1 Sep 14 The first Cat 972M XE wheeled loader in the UK is set to arrive at Scottish quarrying firm William Thompson & Son in October.

Caterpillar’s XE models use an integrated Cat continuously variable transmission (CVT) system, rather than the standard torque converter. This delivers fuel savingsof up to 25%, the manufacturer claims.

A hydraulic pump and motor (variator unit), allows for a smooth and continuous gear ratio change between engine speed and machine speed. This variator unit allows the machine to run at a much lower RPM, meaning that the functioning RPM of the XE model runs at 500 less than the standard Cat 972M. This is expected to save William Thompson & Son an average of four litres of fuel for every hour that its Cat 972M XE is in use.

When it arrives on site in Dumbarton next month, the new 26-tonner will join a Cat 336EL hybrid excavator that the company already has.

Director Andrew Thompson said: “At William Thompson & Son we strive to be at the cutting edge of new technologies enabling us to maximise productivity, minimise cost, whilst reducing our carbon footprint. The new Cat machines are leading the way in our industry. Therefore it was a simple business decision to integrate them into our fleet and benefit from the value they will add to our operation.”
