Hitachi launches new ZAXIS-7 compact excavators

Hitachi Construction Machinery Americas has introduced a pair of ZAXIS-7 compact excavators: An ultra-short-tail swing radius on the ZX75US-7 allows access to confined spaces, while an ultra-short-tail swing radius with swing boom model ZX85USB-7 productively digs next to walls and guard rails.

Power is provided on both machines by turbocharged Yanmar diesel engines, which feature power/economy work modes to tailor the machine’s performance to the task. The power mode provides higher engine speeds when extra horsepower is needed, while the economy mode reduces engine speed when performing normal work. A standard auto idle system automatically reduces the engine to idling speed when all control levers are left in neutral for longer than 4 seconds.

An optional attachment replacement support system simplifies swapping work tools. Attachment flow settings can be adjusted from the monitor and the operator can name and store up to 12 settings. An auxiliary function lever (AFL) is available with an analog switch, trigger switch and horn for running attachments such as a breaker or an attachment with swing.

Other features on the new ZAXIS-7 compact excavators include:

• The Aerial Angle peripheral vision camera system provides a wide 270-degree bird’s-eye view of the machine’s immediate environment. The operator can quickly and easily select from five views on the monitor; a camera allows the operator to see the area right below the counterweight.
• ConSite OIL, a new optional feature, monitors engine and hydraulic oil conditions to proactively catch issues before any fault codes are triggered in the machine – catching oil degradation before damage to critical systems can occur. In addition, ConSite Air allows the excavator to be diagnosed remotely and allows remote software updates.
• An 8-inch (20.32-cm) antiglare LCD monitor provides visibility even in bright surroundings. The monitor also controls the Bluetooth radio.
• Standard long-lasting LED work lights that continue to light up for 30 seconds after the power is turned off for increased safety when exiting the cab at night.
• Cab space has been significantly enlarged versus the previous generation – there is more head clearance when opening the front window, and a low cabin floor height allows improved access.
• A wide opening rear engine cover allows maintenance access. The filters and fuel/water separator are grouped in the pump room for easy ground level inspection and replacement. Features such as remote swing-circle lubrication simplify daily maintenance.
