The Hitachi ZX130-7 and ZX160LC-7 excavators are full-sized hydraulic excavators engineered for a wide range of tasks on the jobsite. The 30,870-lb. (14,000-kg) ZX130-7 offers a maximum dig depth of 19-ft., 9-in. (6.03 m) and a bucket breakout force of 23,380-lbs.
“The ZX130-7 and ZX160LC-7 feature a number of improvements and updates to provide more productivity, performance, operator comfort and fuel efficiency,” said Patrick Baker, product manager, medium and large excavators, Hitachi Construction Machinery Americas Inc.
The ZX160LC-7 has an operating weight of 39,463-lbs. (17,900 kg), a maximum dig depth of 21-ft., 4-in. (6.49 m) and a bucket breakout force of 25,179-lbs. The HIOS IV hydraulic system helps minimize hydraulic loss during operation. It ensures a responsive boom, arm and bucket with intuitive control. The ZX130-7 and ZX160LC-7 feature adjustable attachment, arm and swing priority through the monitor to match machine performance with the attachment.
The ZX130-7 uses a 100-net-hp (74.9 kW) Isuzu engine. A durable Yanmar engine powers the ZX160LC-7, producing 132-net-hp (98.6 kW). It features economy, power and high-power modes to match available power to the working conditions. An auto idle system with auto shut-down control prevents wasted fuel.
The new 8-in. (20.32-cm) LCD, anti-glare monitor includes an attachment preset system, allowing operators to preset flow rates and pressures for up to 16 attachments.
Cab and Visibility
“A larger cab with ergonomic controls on the ZX130-7 and ZX160LC-7 excavators addresses customer demand for a comfortable operator environment. This results in increased productivity through reduced operator fatigue,” said Baker.
The large cab includes a dual adjustable seat and console. This allows operators to find operating positions for long working days in the seat. Pilot controls reduce operator strain and support operator controllability. Switches have been collectively installed on the right side with access to those frequently used.
The quiet cab features four fluid-filled elastic mounts that reduce vibration when travelling. The 8-in. (20.32 cm) monitor also includes Bluetooth radio so operators can remain hands free and focused on the task. LED lights provide visibility in challenging conditions.
Cabs are equipped with Aerial Angle peripheral vision camera system, which provides a wide 270-degree bird’s-eye view of the machine’s immediate environment. The operator can select five different Aerial Angle viewing screens on the monitor. A rear-view camera allows the operator to see the area right below the counterweight.
Durability
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 idler sealing.
The ZAXIS-7 excavators feature a strengthened boom end and foot. For durability, the bushings are installed in the brackets at the boom end and the boom foot.
Operation and Maintenance
“Ease of service was a major consideration when updating the ZX130-7 and ZX160LC-7 excavators. This saves operators time and helps ensure maximum uptime,” said Baker.
Simplified daily maintenance and durability features keep operators right where they need to be — up and running. Wide-open engine covers provide access for maintenance, while filters are within reach and take just minutes to maintain. Access to clean the radiator has been enhanced.
Several enhancements keep dirt and dust out of vital components. A spin-on type fuel filter prevents dust from entering the fuel circuit during maintenance. An inner element of the engine air filter protects the engine from dust ingress while cleaning the outer element. The air conditioner is protected with an internal filter with a seal that prevents intrusion of dust into the air conditioner unit.
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.
A dealer-installed option on the ZX130-7 and ZX160LC-7, ConSite OIL, monitors engine and hydraulic oil conditions to proactively catch issues before any fault codes are triggered in the machine. This helps drive operations by catching oil degradation before damage to critical systems can occur.
