Hitachi Construction Machinery Americas is rolling out its new 7 Series excavators, at ConExpo, including the new ZX210LC-7.
The 49,833- pound excavator has a maximum dig depth of 6.67 metres and a bucket breakout force of 35,520 pounds. The new machine is designed to target the earthmoving, material handling, demolition and underground excavation markets.
“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, for Hitachi Construction Machinery Americas Inc.
The next generation TRIAS III hydraulic system reduces fuel consumption while optimizing performance. As well, 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, which improves 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 is also able to adjust boom raise priority. This can tailor the machine to do everything from truck loading to heavy digging.
The Hitachi ZX210LC-7 is powered by a 164 hp Isuzu engine. It uses a durable diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR) aftertreatment. The engine features work modes to best match available power to the job site conditions, and an auto idle system with auto shutdown control prevents wasted fuel.
Hitachi’s “first-class” cab
Hitachi’s first-class cab ensures operator comfort and reduces fatigue. It starts with a larger cab with increased head clearance. As well, a one-touch adjustable air suspension seat is synchronized to move with the console.
Hitachi has also reduced noise in the cab 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 travelling. A 20.32-cm anti-glare LCD monitor provides visibility, even in bright surroundings.
Easy pilot controls
Low-effort pilot controls reduce operator strain. For convenience, switches have been collectively installed on the right side with easy access to the most frequently used.
For panoramic visibility, Hitachi Construction Machinery Americas created 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.
The Hitachi 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.
To boost uptime, an inner element of the engine air filter protects the engine from dust ingress while cleaning the outer element. The air conditioner is also 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 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,” Baker said.
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.
