quality Used Excavator Equipment & Used Komatsu Excavator manufacturer

The creation of Volvo Construction Equipment’s EC230 electric excavator is the result of proven technology from across the Volvo Group. The 23-tonne electric excavator delivers the same performance as its diesel counterpart, while eliminating emissions and greatly reducing noise, vibration and total cost of ownership. The machine combines Volvo CE’s experience in excavator development with Volvo Penta’s R&D into electric motors and battery systems that has already been proven by Volvo Buses and Mack Trucks. Sung Sook Kim, Volvo CE’s Product Manager for mid-sized excavators, explained the ability to share technology within the group has allowed Volvo to take its electric equipment development beyond compact machinery, without relying on major components from third-party manufacturers. “We designed it, we built it, we manufactured it. So that’s the big difference. This is a mass production machine,” Kim said.   With the battery already in use in trucks, Volvo CE can learn from their experience as well as address safety and durability concerns of battery technology.   “With Mack Trucks, they have been using it two or three years ahead of us,” said Najing Li, Volvo CE’s product manager for sustainable power. “It already has the validation. I think that’s the benefit, the beauty of it.” Electric performance   The EC230 is powered by four of Volvo Penta’s lithium-ion flat pack batteries for a capacity of 264 kWh. With a system voltage of 600 volts, the electric motor delivers a peak 160 kW of power. “Trucks have been using that (flat pack battery) for probably three or four years, and it had been developed long before that,” said Forrest Hooper, Volvo Penta’s Regional Sales Manager. “We have the flexibility to be able to kind of cherry pick and tap into the Volvo Group technology.” The electric excavator features a 1.44 cubic metre bucket capacity, a lifting capacity of 7,560 kg, a 6.7-metre maximum digging depth and a breakout force of 33,500 foot-pounds. The hydraulics system features two main variable displacement axial piston pumps that each provide 208 litres per minute. Combined with the electronic control system and ECO mode, the hydraulic system is optimized to work in harmony with the power source to reduce power loss and improve controllability and response time. The summation system combines the flow of both hydraulic pumps to ensure quick cycle times and high productivity. The arm priority feature gives priority to the arm operation for faster cycle times in levelling and for increased bucket filling when digging. Swing priority provides priority to swing functions for faster simultaneous operations. The EC230 electric excavator was launched in Europe last year, and a handful of machines are now operating in North America. So far, operators report the machine delivers a similar digging force as its diesel equivalent but achieves faster cycle times and reduced noise. “We’re using the same hydraulic systems, same pump and the same main control valve,” Kim said. “So, that performance and productivity is the same, but because of the electric motor you will get instant power. The operator feels it is faster and more responsive.” Advancements in charging   The EC230 electric excavator can run for four to five hours, depending on the application. Using a 150 kW DC fast charger, the machine can be charged up to 80 per cent capacity in about an hour. “How fast you charge also depends on what kind of charger you use. The higher the capacity, the faster is going to charge,” Li said. The 150-kW charger is currently the quickest option for the excavator. However, charging technology is quickly advancing. “We’re talking about charging in five or 10 minutes. So, we definitely will be improving in the future,” Li said.

  Liebherr Mining’s latest addition to its excavator portfolio – the R 9300 Generation 8 (G8) – is now available in Canada. The R 9300 is the second G8 excavator in Liebherr’s product range and as such comes with the latest Liebherr Mining technology as standard. This technology provides the machine with improved onsite performance as well as compatibility with Liebherr’s assistance systems and future product enhancements such as automation, zero emission technologies, and digital services. The first R 9300 to reach Australia is now in service at the Karlawinda gold project. MACA – global contractor that works in the mining, construction, and process engineering sectors – welcomed the machine into its fleet of Liebherr excavators. The R 9300 was chosen not only for its capacity to assist in meeting the production targets of its client, but also for the excavator’s fuel efficiency, its state-of-the-art technology, and its operational effectiveness. The design of the R 9300 was validated with a mine contractor beginning in September 2022. The machine averaged 486 operational hours per month and 94% availability. A second validation conducted in March 2023 achieved a 26-second average cycle time. The R 9300 also attained a fuel efficiency ratio of 9.22 bcm per litre of fuel burned. When considered alongside the productivity of the machine, this establishes the next-level efficiency of the R 9300, according to Liebherr. As a result of Liebherr Mining’s commitment to reducing emissions, the R 9300 has been designed to lower fuel consumption, and therefore decrease the amount of greenhouse gases emitted by the machine. The R 9300’s engine is available in FCO and US EPA Tier 4/EU Stage V compliant versions (with SCR after-treatment technology) to adhere to strict international emissions standards. An electric-drive version of the R 9300 is currently under development and will be available in the near future. To increase productivity and efficiency, a range of design improvements have been implemented in the R 9300. It has an updated attachment design that is lighter and stronger than that of the R 9250. The new attachment comes with high-performance components such as a new stick and boom design and aluminum covers all installed as standard. This lean design has enabled an increase in bucket size in both the backhoe and face shovel configurations. The R 9300 has also been designed for simplified maintenance and a longer service life. The lifespan of the R 9300 has been increased by 33% above the R 9250 to 60,000 hours from 45,000 hours. Further improvements can be found in the cab design of the R 9300. The new cab includes enhanced cabin ergonomics, larger touch screens, a new control panel design, and optimized visibility to help promote operator wellbeing while increasing safety.
