Key Specifications
The ZX250H-3G is powered by the Isuzu CC-6BG1T engine, a six-cylinder, turbocharged, intercooled, and water-cooled engine with a displacement of 6.494 liters. This engine configuration allows the excavator to deliver an impressive rated power output of 125 kW at 2,100 rpm. The combination of turbocharging and water cooling ensures optimal performance even under intense operational conditions.
This engine is designed with durability in mind and complies with the stringent emission standards for its time. The unit's 4-stroke configuration and direct fuel injection technology contribute to both fuel efficiency and lower emissions. The engine is capable of generating a maximum torque of 375 N·m at 1,600 rpm, providing ample power for various digging and lifting tasks.
Hydraulic System
The hydraulic system of the ZX250H-3G is a key factor in its high performance. It features a dual-pump variable displacement axial piston pump system that ensures efficient power delivery. The maximum flow rate of 204 L/min from each of the two pumps provides powerful hydraulic pressure to operate the boom, arm, and bucket. With a maximum hydraulic pressure of 34.3 MPa in the work circuit, this excavator is well-equipped for tasks that require high digging forces.
The machine's hydraulic system also includes advanced components such as axial piston motors for rotation and dual-speed axial piston motors for travel, allowing for both precision and power during operations. These systems contribute to the high digging power, with a bucket digging force of 18,000 kN and an arm digging force of 1,250 kN. These forces make it suitable for both heavy lifting and precision digging tasks.
