Hitachi Construction Machinery Americas' new ZX210LC-7 excavator is designed to handle earthmoving, material handling, demolition, and more challenging jobs. Building on the success of the ZX210LC-6 HP introduced in 2022, the new excavator has been fine-tuned and enhanced for greater power, speed, and precision.
The new machine offers a maximum dig depth of 21 feet, 11 inches, and a bucket breakout force of 35,520 pounds. It is equipped with a number of updated features, including the next generation TRIAS III hydraulic system, which reduces fuel consumption while optimizing performance.
A three-pump system, TRIAS III ensures the machine responds quickly to all control inputs, while minimizing hydraulic losses. A new arm roll-in metering control valve allows hydraulic pump power to be reduced when the arm is operated with a low load. When digging, the roll-in metering control valve reduces hydraulic pressure loss to the tank. This decreases the pump power needed for digging operations, improving fuel efficiency.
Users will find a variety of settings in the ZX210LC-7 that add to the machine's versatility. For example, attachment/arm priority can be adjusted on the monitor to match the attachment or operator's preference. When the attachment and arm are operated at the same time, the operator is able to adjust whether the speed of the attachment or the arm should be prioritized. The operator can also adjust boom raise priority, which can tailor the machine to do everything from truck loading to heavy digging.
The ZX210LC-7 is powered by an Isuzu engine at 164 horsepower, and uses a durable diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR) aftertreatment solution, protecting the environment while preventing downtime. It offers work modes that can be used to best match the available power to job site conditions.
In the cab, operators will find panoramic visibility, increased head clearance, and a one-touch adjustable air suspension seat synchronized to move with the console. Noise, dust, and vibration are all minimized. An eight-inch anti-glare LCD monitor ensures that operators can view the screen in even bright surroundings. The machine is operated with low-effort pilot controls, reducing operator strain, and switches are placed in easy reach.
Hitachi has taken an additional step to improve visibility with its Aerial Angle peripheral vision camera system, which provides a 270-degree bird's-eye view of the machine's immediate environment. The operator can quickly and easily select the view on the monitor that best suits the situation. A rear-view camera allows vision to the area below the counterweight.
Durability is key to the ZAXIS-7 excavators, which feature enhancements to components like the undercarriage and boom that add additional protection and strength.
Maintenance can be tracked using the multifunctional monitor, which indicates preset maintenance intervals every time the key is turned on. Engine oil and coolant levels can be checked from the operator's seat.
Hitachi's telematics system, ConSite, is also being updated along with Hitachi excavators. The system which monitors operational status and issues alerts to upcoming maintenance needs is adding new functionality. ConSite OIL actively checks engine and hydraulic oil, as well as other parameters, catching issues before fault codes are triggered, and improving uptime. ConSite Air allows for remote diagnosis and remote updates of the software.
