Volvo Construction Equipment (Volvo CE) is expanding the global distribution of its EC550E crawler excavator equipped with a Tier 3 engine. With the ability to fill a 35-40-tonne hauler or highway truck with 4-6 buckets, the EC550E is suited to mining, mass excavation and large infrastructure projects.
Short cycle times further boost productivity, made possible by digging forces and lifting capacity more commonly found in a 60/65-tonne excavator. This is complemented by the impressive engine power, reinforced boom and arm, as well as boom/swing and boom/travel priority settings. The long and wide undercarriage is also of 60/65-tonne calibre, providing superior levels of stability and durability.
Kwangsuk Jee, global product manager, Volvo CE, said: “Delivering the type of durability and performance more commonly expected from a 60/65-tonne machine, the EC550E is a crawler excavator which truly punches above its weight. Customers in Tier 3 markets can get ready for up to 35% more productivity and 22% more fuel efficiency, combined with superb operator comfort and outstanding levels of uptime.”
The EC550E is available with a range of optimum-sized heavy-duty rock buckets designed for use in abrasive conditions. Customers can further take control of their productivity with on-board weighing, helping to ensure the optimum amount of material is loaded. The optional system provides real-time information to eliminate under and overloading of haul trucks and also records total tonnage for complete production management.
The next generation electro-hydraulic system improves fuel efficiency with independent metering valve technology (IMVT) and engine/pump optimization, which lowers engine rpm while optimizing power. It provides more precise control compared to a conventional system and contributes towards up to a 22% improvement in fuel efficiency.
With the optional delayed engine shutdown customers can keep their turbocharger working in top condition for longer. To avoid overheating, the intelligent function turns the machine off when the turbo charger has cooled down to the appropriate temperature. The EC550E can also be fitted with a high-performance fuel filtration system which delivers 99.7% water separation efficiency consistently over the full service life of the filter.
