“Volvo is well above the competition when it comes to product support”
incineration process, the ash is quenched in water to help cool it before it is re-handled and loaded onto wagons destined for recycling. This starts a chemical reaction which continues for around three weeks once the material arrives on site. Here it is stored under cover in windrows, curing. During this curing process, the material becomes consolidated taking on the characteristics of a conglomerate which requires further re-handling prior to feeding into the processing plant.
This is where the recently purchased twenty-five tonne EC250E comes in. The machine is deployed to sit on top of the stockpiled material, preparing it for the resident wheeled loader to load and carry it to the primary feeder. “We’ve been using a larger EC380E at our Brentford facility due the nature of the material we receive. As it is stored in the open, it tends to consolidate further and therefore requires a good deal more re-handling before processing. Here at Greenwich the material is under cover and easier to deal with, hence our decision to go with the slightly smaller EC250E,” explains Stuart.
“The new arrival has been equipped to our own bespoke design for the application which can be quite a challenging environment in which to operate. We’ve specified the short dipper arm to give maximum breakout force, an hydraulic hitch and a selection of buckets which can be interchanged to deal with the varying nature of the material,” explains Stuart. “The machine itself has been coated in two pack lacquer on the superstructure panels as well as the cooling package, to prevent accelerated wear. The other major modification which Kokurek has done for us is in extending the superstructure chassis rails to allow
an 800L water tank to be sandwiched in between the counterweight and the engine compartment. This has been added to feed a Dynaset HPW water suppression system which has been piped down the length of the equipment and this assists with the dust suppression inside the shed.” Other features on the EC250E include a full LED lighting package, reversible fan, reverse and side mounted cameras and full autolube system. The EC250E is powered by a Volvo eight cylinder engine developing 213hp. 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. A larger EC300E was purchased earlier in the year by
Day Aggregates which started work when the Greenwich Plant was commissioned but since the arrival of the EC250E this unit will undergo similar treatment in terms of anti-corrosion protection and will then be deployed elsewhere. The Volvo Care Cab on both excavators offers a large roomy interior with plenty of leg room and foot space. The excellent all round visibility is enhanced by pressurized and filtered cab air supplied by a 14 vent, climate control
