The ZX210LC-7 builds on the success of the ZX210LC-6 HP.
The 49,833-lb. Hitachi ZX210LC-7 excavator has a maximum dig depth of 21 ft. 11 in. and a bucket breakout force of 35,520 lbs. (158 kN). Targeting the most popular segment of the excavator market, the ZX210LC-7 offers unparalleled power, speed and precision to excel in diverse applications such as earthmoving, material handling, demolition, underground excavation and more, according to the manufacturer.
"The ZX210LC-7 builds on the success of the award-winning ZX210LC-6 HP introduced last year. We have focused on fine-tuning and enhancing the core capabilities of the ZAXIS-7 excavators to maximize efficiency so you get more for less," said Patrick Baker, product manager, medium and large excavators, Hitachi Construction Machinery Americas Inc.
For instance, the next generation TRIAS III hydraulic system reduces fuel consumption while optimizing performance. The three-pump system provides quick response 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.
The ZX210LC-7 offers a variety of settings that increase the excavator's versatility. Attachment/arm priority can be adjusted on the monitor to match the attachment or the operator's preference. When the attachment and arm are operated at the same time, the operator can adjust whether the speed of the attachment or the arm should be prioritized. The operator can also adjust boom raise priority. This can tailor the machine to do everything from truck loading to heavy digging.
An Isuzu engine pumps out 164 hp (122 kW). It uses a durable diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR) aftertreatment solution to protect the environment while preventing downtime. It features work modes to best match available power to the job site conditions. An auto idle system with auto shutdown control prevents wasted fuel.
First-Class Accommodations
A first-class cab ensures operator comfort and reduces fatigue. It starts with a larger cab with increased head clearance. A one-touch adjustable air suspension seat is synchronized to move with the console.
Noise has been minimized by increasing the thickness of the rear glass. Improved airtightness of the cab keeps the dust out, even when the air conditioner is started.
Four fluid-filled elastic cab mounts reduce vibration when traveling. An 8-in. anti-glare LCD monitor provides visibility, even in bright surroundings. It also controls the Bluetooth radio. The operator can listen to music and make hands-free calls from the cab. Long-lasting LED lights provide visibility in challenging conditions.
Low-effort pilot controls reduce operator strain. For convenience, switches have been collectively installed on the right side with easy access to those frequently used.
Designing cabs with panoramic visibility helps create a safe and comfortable working environment.
Hitachi Construction Machinery Americas Inc. takes this a step further with its Aerial Angle peripheral vision camera system. It provides a wide 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 the operator to see the area right below the counterweight.
Durability Built In
Hitachi excavators are renowned for durability and the ZAXIS-7 excavators feature enhancements to critical components such as the undercarriage and boom. On the undercarriage, an anti-mud-compaction lower roller design helps prevent mud from entering and damaging the oil seals. The upper and lower rollers also feature improved idler sealing. A track undercover protects the joint from potential damage.
The ZX210LC-7 features a strengthened boom end and foot. For durability, the bushings are installed in the brackets at the boom end and the boom foot.
Boost Uptime
Tracking maintenance is simplified with the multifunctional monitor. It indicates preset maintenance intervals each time the key is turned on. Engine oil and coolant levels can be checked right from the operator's seat.
Design enhancements help protect critical components from the environment. An inner element of the engine air filter protects the engine from dust ingress while cleaning the outer element. Even the air conditioner is protected with a sealed internal filter that prevents intrusion of dust into the air conditioner unit.
Using telematic tools to monitor machine health helps boost uptime. ConSite, which remotely monitors operational status and alerts owners and operators to upcoming maintenance needs, is making a leap forward.
"ConSite OIL actively checks engine and hydraulic oil, along with other parameters, so you can see a problem before it's even a fault code. This increases operator uptime," said Baker.
A standard feature, ConSite OIL, monitors engine and hydraulic oil conditions to proactively catch issues before any fault codes are triggered in the machine. This helps drive uptime by catching oil degradationbefore damage to critical systems can occur. This allows operators to focus on the work that needs to be done.
ConSite Air allows the excavator to be diagnosed remotely. It also allows remote updates of the software.
The servicing dealer can remotely diagnose issues that may arise, leading to increased uptime. A ConSite response team is on standby to rapidly resolves issues as they emerge.
