The new EC220D takes over from a Volvo EC210LC that was originally supplied back in 2007 for the Colchester site and which has since taken up residence at the company’s other sand and gravel extraction quarry near Dunmow. “The performance and reliability of the EC210 cannot be faulted and this was the primary consideration when we looked to add another excavator to our fleet,” comments director David Hunter. Performance and reliability aside, SRC Aggregates looks forward to significant fuel savings with the EC220D and together with a weight and specification advantage will find even more improvements in overall performance.
The EC220D 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 significantly improves hourly fuel consumption with shorter cycle times. Operators can select the best work mode for the task at hand, ensuring optimum performance and fuel efficiency. Modes include: I-idle, F-fine, G-general, H-heavy or P-power, with the machine automatically setting the appropriate engine speed for the work mode and ECO mode is a new feature that works in G to H (or 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. Eco mode provides better fuel efficiency without loss of performance in most operating conditions.
The new ‘smart’ hydraulics system is designed for high productivity, high digging capacity, easy manoeuvrability and class leading fuel economy. It features improvements that increase total flow and cycle times. Independent and simultaneous movements of the digging equipment are controlled by an ‘automatic sensing work mode’. It can also prioritize flow according to the work being done — e.g. to the boom for faster raising when loading or in deep excavations; to the arm during levelling or swing during large slewing angles.
Besides general extraction of sand and ballast, the new EC220D is also being utilised to construct a large reservoir on the 160 acre Crown Quarry site commissioned by the Ardleigh Reservoir Committee. The new excavator joins a mixed fleet of equipment including articulated haulers, loading shovels and excavators.
