Core configuration

Dynamic system
Cat C9 diesel engine: Uses ACERT technology to balance fuel efficiency with low emissions.
Turbocharged intercooling: suitable for high altitude and heavy load.
Fuel consumption: Average 15-22 L/h (depending on operation intensity).
Transmission system
Power shift transmission: 3 speed forward /3 speed backward, support stepless transmission control.
Differential steering: Precise steering and low track wear.
Hydraulic system
Flow rate: 230 L/min (main pump)
Pressure: 24.5MPa
Automatic blade control is available as standard (optional with Laser GPS).

Applicable scenarios

earthwork
Site leveling, roadbed excavation, filling operations (efficiency: 300-600 m³/ day).
Mines and quarries
Hard rock stripping with ripper (recommended configuration: single tooth/multi-tooth ripper).
Agricultural and forestry reclamation
Root cleaning, ditch digging (need to install protective fencing).
Post-disaster reconstruction
Debris removal, road repair (adaptive Angle shovel or sanitation shovel).

Maintenance

Routine inspection
Check the track tension (droop: 20-40 mm).
Clean the radiator (to prevent dust clogging and overheating).
Regular maintenance
250 hours: Replace engine oil and hydraulic oil filter.
1,000 hours: Check the wear of the track chain pin (allowable wear ≤5 mm).
2,000 hours: Calibrate blade hydraulic valve, replace coolant.
Common fault handling
Track derailment: Adjust tension and check guide wheel bearings.
Hydraulic system leakage: Replace the O-ring seal or high-pressure hose.
Engine power drop: Clean or replace the air filter and check the turbocharger.
