18-ton crawler excavator is the golden tonnage of medium-sized construction machinery. It has both efficient operation capabilities and site adaptability. It is the main model in earthwork engineering, mining, municipal construction and other fields. Compared with 8-12 ton models, its power, stability and versatility are significantly improved, and it can meet more complex construction needs.

Core characteristics

1. Powerful power and efficient operation

Engine:

Standard 100-130kW (135-175 horsepower) turbocharged diesel engine (such as Cummins, Isuzu, Volvo).

Comply with National IV/Euro V emission standards, fuel consumption is about 12-18L/h (depending on working conditions).

Hydraulic system:

Dual pump dual circuit load sensitive system, smarter flow distribution, smooth compound action.

Optional boost mode (short-term increase in hydraulic pressure 10-15%).

Operation capacity:

Standard bucket capacity: 0.6-0.9m³ (rock bucket 0.4-0.6m³).

Maximum digging depth: 5.8-6.5 meters (extended arm can reach 7.5 meters).

Bucket digging force: 100-120kN (about 10-12 tons of force).

2. Structural design and stability

Track system:

Wide steel tracks (width 2.5-3.0 meters), ground contact pressure 40-50kPa, more stable in wetland and slope operations.

Optional rubber tracks (for hardened road protection).

Working device:

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

Optional variable wheelbase chassis (such as Sany SY195C) to adapt to complex terrain.
