Product catalog summary

Engine Specifications
The ZAXIS 85USB-3 is equipped with an Isuzu 4LE2X engine, providing 54 hp (40.5 kW) at 2,000 rpm. It meets EPA interim Tier-4 emissions standards and includes a turbocharged aspiration with an intercooler. The engine has a displacement of 133 cu. in. (2.2 L) and operates efficiently with a 70% off-level capacity.

Powertrain and Travel
The machine features a two-speed propel system with automatic shift, achieving a maximum travel speed of 1.9 mph (3.1 km/h) in low and 3.1 mph (5.0 km/h) in high.

Hydraulic System
The open center, load-sensing hydraulic system includes three variable-displacement axial piston pumps with a maximum rated flow of 2 x 20.9 gpm + 16.3 gpm. System relief pressure is set at 566 psi, with operating pressures for implement, travel, and swing circuits at 3,771 psi, 4,554 psi, and 3,626 psi, respectively.

Undercarriage and Swing Mechanism
The undercarriage includes 1 carrier roller and 5 track rollers per side, with 40 triple semi-grouser shoes per side. The swing mechanism operates at a speed of 10.5 rpm with a torque of 12,244 lb.-ft.

Operating Dimensions and Capacities
The machine's operating weight is 18,821 lb. with a full fuel tank and standard components. It offers a maximum reach of 25 ft. 3 in. and a maximum digging depth of 14 ft. 8 in. Lifting capacities vary based on arm length and configuration, with hydraulic-limited and stability-limited capacities clearly defined.

Bucket Options
A variety of bucket types are available, including heavy-duty and ditching buckets, with capacities ranging from 0.40 to 0.66 cu. yd. Recommendations are provided based on material type and conditions.

Serviceability and Maintenance
Serviceability is enhanced by features such as a fluid analysis program, part of Hitachi's Customer Personal Service (CPS) strategy to control costs and increase operational efficiency.
