Technical Description
The Hitachi ZX135US-6 is a compact, zero-tail-swing hydraulic excavator engineered for high performance in confined spaces. Powered by a 101 hp (75 kW) Isuzu 4JJ1 engine meeting EPA Final Tier 4 and EU Stage IV emissions standards, it delivers reliable, fuel-efficient operation with turbocharged and charged air-cooled aspiration. The hydraulic system features two variable-displacement axial-piston pumps, providing robust implement and travel pressures of 4975 psi and 5047 psi, respectively, for maximum digging and lifting power. With a net operating weight of 30,644.3 lbs, the ZX135US-6 offers excellent stability and lifting capacity. The excavator is equipped with pilot levers for precise, low-effort control and a direct-drive, suction-type cooling fan for optimal engine temperature management. Standard capacities include a 58.2-gallon fuel tank, 41-gallon hydraulic system, and 15.9-gallon hydraulic tank, supporting extended operation. The undercarriage features 44 shoes per side, 7 track rollers, and 1 carrier roller per side, with a drawbar pull of 11,216 lbs and a maximum travel speed of 3.5 mph (5 kph). The swing mechanism delivers a speed of 13.3 rpm, ensuring efficient cycle times. The electrical system includes two 12V batteries (3000 CCA), a 50-amp alternator, and two halogen work lights. With a minimum swing radius of 96.5 inches, the ZX135US-6 excels in tight environments, making it ideal for urban construction, utility work, and other demanding applications.
