Volvo Construction Equipment is entering the 50-ton class for excavators with two models — the EC530E and EC550E — made for heavy-duty digging, mass excavation and large-scale site preparation.
When coupled with large buckets, the EC530E and EC550E are suited to fill articulated haulers in the 30- to 40-ton class, requiring fewer passes to load them and reducing cycle times. This combination can boost productivity by up to 20 percent.
Also characteristic of bigger equipment is the super-rigid reinforced undercarriage, providing durability and strength. This is supported by equally sturdy lower and upper frames. The EC550E undercarriage has a long and wide lower frame, giving it extra stability when working with heavier loads. Both machines' boom and arm feature a larger pin size for added strength.
Fuel efficiency with IMVT
The electro hydraulics system contributes to a 25 percent improvement in fuel efficiency due to Independent Metering Valve Technology (IMVT) that, due to intelligent electronic control, offers more precise operation and efficiency than a traditional mechanically coupled hydraulic system. Engine pump optimization lowers engine speed while maintaining power.
The EC530E and EC550E offer high levels of control and efficiency for all applications, including creep mode for precise lift-and-carry work and optional Comfort Drive Control (CDC). CDC helps reduce operator fatigue by allowing the excavator to be steered with joystick rollers instead of pedals.
Operators can also select functions like boom/swing and boom/travel priority, which enables one function to take the lead over another. The boom-down speed can also be adjusted, giving optimum control for tasks that require extra precision. New boom-and-arm bounce reduction technology lessens machine shock.
Productivity and uptime features
Operators are further assisted by the optional Dig Assist machine control system, powered by Volvo Co-Pilot and designed to deliver excavation accuracy in a fraction of the time of conventional methods.
To increase uptime, hydraulic pilot lines have been removed, reducing the number of couplings needed. Maintenance time and costs are further reduced by the recent extension of Volvo engine oil change intervals to 1,000 hours when using Volvo VDS 4.5 oil.
The EC530E and EC550E are eligible for ActiveCare Direct, Volvo's advanced telematics service.
