More Volvo machines for Essex aggregates supplier

A year after buying a new Volvo EC220D crawler excavator, Essex-based SRC Aggregates has gone back for more.

The latest deal includes a pair of 30-tonne A30G articulated haulers, an L120H and L150H loading shovels, another EC220D and the slightly larger 25-tonne EC250E crawler excavators.

These machines have gone to work at SRC Aggregates Crown Quarry sand and gravel extraction facility near Colchester and at Highwood Quarry near Great Dunmow.

SCR director David Hunter is anticipating significant fuel savings. The EC220D, for instance, benefits from the use of Volvo’s Stage IIIB D6 engine, delivering 175hp (129kW) of power and 849Nm of torque, coupled to an improved hydraulic system with larger pumps, which in turn improve hourly fuel consumption with shorter cycle times.

The larger EC250E excavator is equipped with a Stage IV Volvo eight-litre engine developing 215hp. Operators can choose from operating modes: I-idle, F-fine, G-general, H-heavy or P-power, with the machine automatically setting the appropriate engine speed for the work mode. ECO mode is a new feature that works in G, H and P mode. Pump flow is controlled for combined digging and swinging operations to reduce the flow loss through the overload relief valves, while maintaining digging power and maximum swing torque. In most operating conditions Eco mode provides better fuel efficiency without loss of performance.

Similarly the new Volvo L120H and L150H wheeled loaders have Volvo Stage IV 8 and 13 litre engines respectively, with a matched Volvo powertrain and intelligent hydraulics that supply power only on demand, thus saving fuel.

The new Volvo A30G articulated haulers have the 11 litre version of the Volvo Stage IV engine. The trucks have a load carrying capacity of 28 tonnes and a heaped body volume of 17.5m³. As with the loading shovels, the trucks have Volvo powertrain components to match the engine.
