Generation 8 dozer is ‘another step forward’

The first of Liebherr Rental Ltd’s latest generation of dozers has gone into operation with the UK’s largest independent construction materials business.

The PR736 recently joined the rental fleet at Liebherr and was quickly turned around after Breedon Group commissioned the Generation 8 model to work at one of its quarries in North Wales.

Supplied in low ground pressure specification with 914mm single grouser tracks and a 4.1m³ outside-mounted straight blade pushing its weight up to 23 tonnes, the latest arrival combines low fuel consumption with ‘best in class’ pushing power.

Breedon is using the machine for quarry development works and it is under the control of Martin Davies, one of its most experienced operators. “I’ve been on the older 736 and the 746 we have at our quarry and they have both been brilliant dozers. But this is another step forward,” he said.

The PR736 is powered by a Stage V Liebherr EVO engine with increased nominal output over the previous model. Electronically controlled work hydraulics allow fast and precise grading. The operator can decide how much power to draw from the engine and set the hydrostatic drive to work at a constant speed when shifting large volumes of material. When on fine trimming work, the ECO mode delivers the correct amount of power but with lower fuel consumption.

Cab interior has been upgraded with an improved, quieter operator station and two new Operator Assistance Systems are included as standard: Free Grade provides active blade stabilisation when grading and Definition Grade allows automatic blade positioning when creating simple 2D surfaces. An optional 3D Grade from Topcon is available when more complex modelling is required.

Gareth Blythin, Liebherr Rental’s Contracts Manager, commented: “The new Generation 8 machine has taken an already excellent and well-received tractor and made it even better for both operator and owner.”
