Key Advantages

The crawler has strong carrying capacity (2.5 tons), large climbing capacity, simple operation and high drilling efficiency
Four hydraulic supporting feet on the crawler chassis, each controlled separately for stable platform fixation
Square tube welded crawler platform and drilling tower for high strength and good rigidity

Maintenance Guidelines

Service temperature range: -25°C to +55°C
Avoid exposure to chemicals, engine oil, or sea water salt which accelerate track aging
Protect tracks from sharp protrusions (steel bars, sharp stones) that may cause damage
Always retract tower after drilling operations
