8-ton crawler excavator is the main model for small and medium-sized projects. It combines flexibility, efficient operation and versatility, and is suitable for a variety of scenarios such as municipal construction, farmland water conservancy, and construction sites. Compared with the 6-ton model, it has greater digging force, stability and operating range, while still maintaining good transfer convenience.

Core characteristics

1. Power and performance

Engine: Equipped with 45-55kW (60-75 horsepower) diesel engine (such as Yanmar, Isuzu, Cummins), in line with National IV/Euro V emission standards, fuel consumption 5-7L/h.

Hydraulic system:

Using load-sensitive hydraulic system, the operation is more precise and the compound action is smooth.

Optional dual pump confluence technology (some high-end models) to improve work efficiency.

Working capacity:

Standard bucket capacity: 0.25-0.35m³ (can be equipped with 0.15m³ narrow ditch bucket or 0.4m³ enlarged bucket).

Maximum digging depth: 4.0-4.8 meters (extended arm can reach 5.5 meters).

Bucket digging force: 50-60kN (about 5-6 tons).

2. Structure and stability

Track design:

Steel track (standard) or rubber track (optional, to protect hardened road surface).

Track width 1.8-2.2 meters, ground pressure 35-45kPa, good wetland adaptability.

Working device:

Reinforced boom and dipper, suitable for heavy-load excavation and crushing operations.

Optional retractable chassis (such as XCMG XE80D) to enhance slope stability.
