Volvo Construction Equipment is integrating its hydraulic hybrid technology to its newest generation of excavators with the EC260 Hybrid, EC300 Hybrid, EC370 Hybrid, EC400 Hybrid and EC500 Hybrid.
This selection of crawler excavators ranges from 26 tons to 50 tons and Volvo CE says they represent the future of excavator design. Additionally, the EC400 Hybrid and EC500 Hybrid are now the biggest models among Volvo CE’s hybrid offerings.
According to Volvo CE, these new models deliver up to 20 percent better fuel efficiency than the previous series’ conventional models and a 15 percent reduction in CO2 emissions – all without sacrificing productivity.
“Our hybrid excavators are designed to improve fuel efficiency and reduce environmental impact while maintaining high performance,” says Sejong Ko, product manager for large excavators at Volvo CE. “These excavators lower a fleet’s emissions, making them a more environmentally friendly and fuel-efficient choice, especially for work in urban areas.”
Technology meets power
Volvo CE says its hybrid excavators provide a competitive edge with its hydraulic hybrid technology. It works by harvesting “free” energy generated by the down motion of the excavator’s boom. The machine uses this boom-down motion to charge the accumulator and then uses the stored energy to drive the assist motor when needed, in turn powering the engine system.
The new excavators were introduced last May and are already paying dividends thanks, in part, to their increased power and efficiency, enhanced operator environment and improved human-machine interface, according to the company.
The new electro-hydraulic system requires fewer hoses and couplings, minimizing maintenance requirements and costs while increasing reliability, Volvo CE says.
Equipment features
A robust undercarriage with reinforced idle frame, track links and bottom rollers offers strength and durability. The company adds that operators can tackle tough jobs with the strengthened bucket linkage with steel strip, heavy-duty superstructure undercover and easy-to-replace bolt-on wear plates.
Operators can add smart services like Volvo Active Control and Dig Assist with On-Board Weighing. By doing so, Volvo CE says operators can level up their precision and productivity.
