The ZX75US, a medium-sized tailless excavator from Hitachi Construction Machinery Co., Ltd.'s new Zaxis series, offers impressive performance with a working weight of 8,035 kg. It is powered by a 54 horsepower engine, features a standard bucket capacity of 0.28 m³, and delivers a strong traction force of 5,600 kg, making it ideal for a wide range of construction tasks.
Equipped with Hitachi's advanced HIOS engine and hydraulic system, the ZX75US optimizes power output while maintaining balanced pressure and flow in the hydraulic system. This results in improved fuel efficiency and enhanced productivity, helping operators complete jobs faster and more efficiently.
The excavator’s control system is designed for simplicity, using a single operating mode that boosts driver efficiency and makes it easier to adapt to different working conditions. Its versatile design allows for the use of various attachments, and the tailless rotation feature enables operation in tight or confined spaces, expanding its application possibilities.
In terms of reliability, the ZX75US is built to last. It includes long maintenance intervals—such as 500 hours for oil changes and 4,000 hours for hydraulic oil changes—along with reinforced metal bushings, tungsten coating on the arm, and anti-corrosion treatments. These features ensure durability and reduce downtime. The machine also comes with user-friendly lubrication and maintenance systems, making upkeep quick and straightforward for operators.
