Hitachi Construction & Mining Division, an operating division of John Deere Construction & Forestry Company, is highlighting its reliable solutions at MINExpo. Hitachi product experts will be at Booth 8525 (Central Hall) to answer mining questions and discuss Hitachi’s new EX-7 Series mining excavators, haul trucks, sustainability, technology and more.
“We can’t wait to talk about Hitachi’s reliable solutions for the mining industry,” said Brian Wells, Division Sales Manager, Hitachi Construction & Mining Division. “There’s truly something to be said about connecting in person and being able to share with our customers what makes Hitachi’s equipment so efficient, reliable and durable. From how we’re achieving superior productivity to the environmentally friendly products we’re manufacturing, there’s no shortage of topics to discuss.”
As just one way that Hitachi brings reliable solutions to life, the EX-7 Series includes the EX1200-7, EX2000-7, EX2600-7, EX3600-7 and EX5600-7 – available as electric or fuel-efficient models that help reduce total costs of ownership. With the EX2600-7, EX3600-7 and EX5600-7, customers can choose from a Cummins or MTU EPA Final Tier 4 (FT4) engine option. For non-regulated countries, customers can choose from a Cummins or MTU engine option that features fuel consumption optimisation (FCO) technologies that contribute to improved efficiency. For example, on the EX3600-7, the Cummins FT4 engine (which also has FCO technologies but uses DEF) contributes toward four percent net fluid savings while the MTU FCO engine without DEF features a 7% net fluid savings as compared to the previous model, the EX3600-6.
The EX-7 Series features improved hydraulic systems with a flow regeneration valve to reduce power requirements from the hydraulic system and engine, lowering fuel consumption and improving pump life. Additionally, these excavators focus on safety features such as a newly designed cab, a folding stairway, an emergency evacuation system and option Aerial AngleTM, which is popular among customers and works as a 360° vision system.
Road to zero emissions
Hitachi offers several solutions on its road to zero emissions. Trolley and retrofit battery trucks will be highlighted, including how the sustainable and environmentally-friendly products can be leveraged to optimise mining operations. Hitachi’s trolley technology utilises DC-powered overhead lines to power trucks up hills. When the truck operator connects to the line, the hauler switches to trolley power, resulting in an increase in speed up the grade and reduced emissions when compared to engine power alone. The system integration is all packaged through Hitachi – from components to support.
“Equipment that is going electric has the opportunity to demonstrate greater reliability and efficiency,” added John Schellenberg, Hitachi Mining Product Manager. “With ‘Reliable Solutions’ being a big part of the Hitachi brand, that's important to us. We continue to focus on integrating technology to reduce emissions.”
Another key product line is the EX-7E (Electric) Series mining excavators, which includes the EX2600-7E, EX3600-7E and EX5600-7E. These electric models run directly off substations and build on the proven efficiency of Hitachi’s existing EX-6E Series excavators.
One of the key benefits of a Hitachi EX-7E Series mining excavator is efficiency. For example, a high torque motor replaces the conventional combustion engine. Electric motors are able to produce high torque with greater efficiency with fewer service intervals than a diesel engine. Also, with the new electronic pump regulators, pump control is taken to the next level with higher precision in matching hydraulic power to the load demand. Reduced ownership and operating costs are also benefits of buying electric, which no longer require or minimise service parts such as oil, filters, coolant or fan belts. Also, large components required for engines are eliminated including radiators, air filters, mufflers and exhaust after treatment devices where required.
Additionally, product experts will be discussing Hitachi’s line of haul trucks: the EH3500AC-3, EH4000AC-3 and EH5000AC-3. These trucks feature Hitachi’s Advanced AC-Drive System propulsion technology, which outperforms previous systems through its simplicity, improved efficiency and enhanced dependability, resulting in technologically advanced trucks. Through vertical integration, these trucks are designed, built and supported by Hitachi. Autonomous haulage technology developments and the benefits of integrating Wenco’s fleet management and dispatch system will also be highlighted.
