Hitachi
Hitachi Construction Machinery Americas unveiled the ZX210LC-7H Super Long Front (SLF) excavator for the North American market. It provides 50 feet 4 inches (15.35 m) of reach at ground level and a 39-foot 2-inch (11.94-m) dig depth with fewer trade-offs, due to its dedicated design. A proprietary hydraulic circuit has been engineered for smooth and safe operation.
The new excavator includes an upgraded swing motor for next-level reach and control, as well as Hitachi genuine bucket attachments that pair perfectly with the new ZAXIS-7 Super Long Front excavators.
A part of the ZAXIS-7 series, the 54,900-pound (24,900-kg) ZX210LC-7H SLF is a dedicated long-reach excavator that puts owners and operators in complete control. This excavator meets the needs of customers in North America who dredge riverbeds, dig canals or perform projects that require extended reach.
The ZAXIS-7 SLF series offers unique features and functionalities that continually elevate user experience and safety.
ZAXIS-7 SLF provides a difference workers can feel with a redesigned operator station featuring a larger, more comfortable space with less vibration and noise. The heavier counterweight, proprietary hydraulic circuit and enhanced swing motor provide confidence while operating the super long arm.
An updated hydraulic control valve provides an immediate response, even when operating at or near maximum extension. Two work modes – Economy and Power – allow operators to tailor operations for job-site conditions.
An AERIAL ANGLE camera gives users a 270-degree bird’s-eye view where they can choose from multiple image options to see the machine’s immediate environment on an 8-in (20.32-cm) antiglare LCD monitor. The monitor also controls the Bluetooth radio, which allows operators to listen to music and make hands-free calls while in the pressurized, quieter cab featured on all ZAXIS-7 excavators.
To further provide customers peace of mind, ZAXIS-7 excavators include a unique innovation: ConSite Oil. Two sensors detect if oil quality has deteriorated and transmit data to Global e-Service. This helps drive uptime by catching oil degradation before damage to critical systems can occur — reducing maintenance and unscheduled downtime.
CASE
CASE Construction Equipment has expanded its EV toolbox for municipal crews, utility teams, urban construction and other contractors with the commercial release of its 580EV, the industry’s first electric backhoe loader.
The next generation of EV equipment from CASE offers crews zero-emissions, low-noise solutions for a wide range of unique jobsite demands — from overnight construction, to work in urban centers or other close-quarter environments where noise and emissions must be kept to a minimum. The expanded CASE EV offering matches the performance and power of its diesel counterparts while delivering unique advantages like lower fuel costs and less maintenance.
“With the 580EV electric backhoe loader, we took an industry staple and designed it as a purpose-built EV to help crews meet increasingly unique jobsite demands and win more contracts on projects that prioritize sustainability criteria,” said Terry Dolan, vice president, North America, CASE Construction Equipment.
The new CASE 580EV electric backhoe loader carries over the same dimensional loading and digging specifications and delivers the same breakout forces as the popular four-wheel-drive, 97-horsepower CASE 580SN diesel model. This marks an upgrade in performance since CASE first debuted its Project Zeus electric backhoe concept in 2020.
Powered by a 400-volt, 71-kilowatt-hour lithium-ion battery platform that’s charged with the same type of Level 2 J1772 adapter found in automotive EVs, the new electric backhoe loader is designed to deliver up to eight hours of operational run time on a single charge, depending on the application. The battery platform also uses an advanced thermal management system with system-specific cooling circuits to better regulate temperatures and help maintain performance in hot or cold conditions.
The four-wheel-drive 580EV uses two independent electric motors for the PowerDrive transmission and hydraulic pumps feeding the loader, backhoe and steering systems to minimize energy consumption and improve performance in loading applications. The 14-foot backhoe also includes an Extendahoe to boost reach, while features like ProControl swing dampening, PowerLift/PowerBoost and electrohydraulic controls improve precision and ease of use on the job site.
Electrification also provides performance advantages like instantaneous torque response and peak torque at any RPM, so operators don’t need to wait for an internal combustion engine to ramp up to meet load demands.
CASE will also make two more EV models commercially available in the coming months. The CASE CX25EV electric mini excavator and the CASE CL36EV electric compact wheel loader will round out the CASE EV lineup for a total of five machines.
A bigger, more powerful version of CASE’s existing electric mini excavator, the 2.5-metric ton CX25EV delivers emissions-free performance and maneuverability well-suited for urban and infrastructure sites with high traffic. This highly versatile machine includes hydraulic flow settings and up to three auxiliary circuits that can be paired with a variety of quick couplers and attachments. It’s also equipped with electrohydraulic controls and a short-radius design, making it easy to maneuver in tight spaces.
The 3.6-metric ton CASE CL36EV electric compact wheel loader delivers the same power and performance as comparably sized diesel-powered loaders, along with simplified maintenance and lower lifetime total cost of ownership. This versatile machine can be matched with a full range of attachments. It also features a hinge-pin height of over 10 feet, making it an ideal solution for supply yards, large-scale building renovations or projects where indoor operation is required.
CASE Construction Equipment is a global, full-line manufacturer of construction equipment that combines generations of manufacturing expertise with practical innovation.
