Hitachi Construction Machinery Americas continues to add new features to enhance the performance and comfort of ZAXIS-5N compact excavators ranging from 1.10 to 6.61 U.S. tons. A short tail swing radius (U) or ultra-short tail swing radius with swing boom (USB) makes it easier to work around buildings, walls, guardrails and other structures.
The latest upgrades to the ZAXIS-5N compact excavators include:
- 5-stage auxiliary flow rate changer on the ZX50U-5N to ZX60USB-5N
- Blade float option on the ZX30U-5N to ZX60USB-5N
- Complete hydraulic quick coupler piping on premium versions of the ZX30U-5N to ZX60USB-5N
- Second auxiliary hydraulic piping on premium versions of the ZX30U-5N to ZX60USB-5N
- LED work lights
- USB power outlet available on cab-equipped excavators
Several features enhance attachment compatibility, including an auxiliary flow rate changer. On the ZX30U-5N to ZX35U-5N, the operator can match the flow rate of the auxiliary hydraulic circuit to the requirements of the attachment being used with either a low or high setting. The ZX50U-5N to ZX60USB-5N excavators now feature a multistage flow rate changer that allows the operator to select five different hydraulic flow settings for increased productivity and efficiency.
Hydraulic quick coupler piping and second auxiliary hydraulic piping are preinstalled on premium versions of the ZX30U-5N to ZX60USB-5N. The second auxiliary hydraulic piping is very beneficial for popular tilting and rotating attachments. Other ZAXIS-5N excavators in this range come with mounting points built in for hydraulic quick coupler piping. This eliminates welding of brackets for quick coupler lines and simplifies installation of quick coupler piping.
An auxiliary function lever (AFL) includes an analog switch, trigger switch and horn for running attachments, such as a breaker or a tool with swing. A standard wedgelock quick coupler makes attachment hookup a snap. A factory-installed bracket for a thumb cylinder simplifies installation.
A standard dozer blade enables the ZAXIS-5N excavators to grade while providing extra stability. A blade float option on the ZX30U-5N to ZX60USB-5N uses the blade’s weight to help perform easier and faster grading operations. The optional factory-installed angle blade version of the ZX35U-5N to ZX60USB-5N allows for enhanced grading and backfilling ability.
ZAXIS-5N excavators have been upgraded with LED work lights that provide enhanced visibility in low-light conditions, improving operator comfort and safety.
Ergonomic hydraulic pilot valve control levers reduce fatigue and provide smooth control. Hydraulic pilot controls for the bucket/thumb and other attachments, boom, swing, travel and blade maximize controllability and ensure smooth operation.
The ZAXIS-5N excavators provide simplified access for maintenance with a hinged door that provides wide-open access to the side-by-side oil cooler and radiator core for easier cleanout. The engine cover slides vertically with less rear projection for ease of maintenance in confined spaces.
To reduce the cost of repair, the traditional curved glass used in the cab has been exchanged with more easily obtainable flat glass.
Installed on top of the battery, a battery disconnect prevents battery discharge during long-term storage. Maintenance is simplified since there is no need to disengage terminals and cables from the battery.
Fuel-efficient Yanmar diesel engines ranging from 14.7 to 53.8 net horsepower (10.8 to 39.6 kW) are paired with proprietary hydraulic systems for optimum performance.
The compact excavators from ZX30U-5N to ZX60USB-5N incorporate power/economy work modes. The power mode provides higher engine speeds for most general digging work, while the economy mode reduces engine speed for lighter digging jobs. This results in lower noise and decreased fuel consumption.
An auto-idling system available on these models further reduces fuel consumption, emissions and noise.
