38-ton crawler excavator is a large-scale construction machinery and is the core equipment for heavy-duty operations such as mining, large earthworks, and port construction. Its power, stability, and operating efficiency far exceed those of 20-30-ton models, while also having a certain degree of site adaptability.

Core characteristics

1. Super Power System

Engine:

Standard 220-260kW (300-350 horsepower) high-pressure common rail turbocharged engine (Cummins QSL9/Volvo D8/Isuzu 6WG1).

Meet National IV/Euro V emission standards, equipped with DPF after-treatment system, fuel consumption 25-35L/h (heavy load conditions).

Hydraulic system:

Three-pump confluence hydraulic system (main pump flow ≥2×200L/min), support boom/arm regeneration function, energy consumption reduced by 15%.

Optional intelligent power matching (automatically adjusts engine and hydraulic output).

2. Structural reinforcement design

Chassis system:

Wide X-type chassis (gauge 3.2-3.8 meters), mining version standard double-ribbed crawler shoes, life increased by 50%.

Optional hydraulic telescopic chassis (such as Liebherr R 938) to adapt to soft soil/slopes.

Working device:

Cast steel boom + box-type bucket arm, torsional strength increased by 30%.

The mining version is equipped with hydraulic oil cooler + air pre-filter as standard.
