Hitachi Construction Machinery Americas has launched six new models to its ZAXIS-7 line of medium and large excavators, targeting improved operator comfort, visibility, fuel efficiency, durability and productivity.
The new ZX250LC-7, ZX300LC-7, ZX350LC-7, ZX490LC-7, ZX690LC-7 and ZX890LC-7 excavators range in operating weight from 26,500 kg to 87,500 kg.
“The new ZX-7 generation of mid- to large-sized excavators features an array of new features and benefits to exceed the high standards set by our customers,” said Patrick Baker, Product Manager for medium and large excavators at Hitachi Construction Machinery Americas. “These excavators have been engineered to be straightforward, effective and productive for the operator while providing an extremely high level of comfort.”
Hitachi prioritized operator comfort by redesigning the operator station. The ZAXIS-7 cab is larger with less vibration and noise for an improved operating experience and reduced operator fatigue. It features increased head clearance and leg room with a one-touch adjustable air suspension seat synchronized to move with the console for simplified adjustments. An ergonomic console layout with intuitive controls enhances operator convenience and visibility on the right side of the cab.
For panoramic visibility, Hitachi has equipped the excavators with its Angle peripheral vision camera system. It provides five different camera views from inside the cab on a 20-cm anti-glare LCD monitor, including a wide 270-degree bird’s-eye view of the machine’s immediate environment.
Next-generation hydraulic systems paired with reliable Isuzu engines provide increased productivity and reduced fuel consumption. Operators can select their preferred ISO or SAE control pattern with a two-way pattern change valve. Standard auxiliary piping and relief valves improve operation and protect the machines while they’re running breaker/hammer attachments.
“The ZX-7 excavators feature heavy-duty boom and stick configurations designed to handle tough working conditions. Newly strengthened undercarriage components, such as idlers, rollers and improved seals carry long-term reliability,” Baker said.
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.
ConSite, which remotely monitors operational status and alerts owners and operators to upcoming maintenance needs, is 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 degradation before damage to critical systems can occur.
The in-cab monitor controls the Bluetooth radio and allows convenient communication. 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.
