The ST 350 Large Crawler Drilling Machine utilizes full hydraulic control and top drive rotation of drilling tools, delivering exceptional drilling efficiency. With its rational overall layout and tractor-mounted or full ground chassis design, it offers excellent maneuverability and flexibility for challenging terrain conditions.

This versatile drilling rig finds applications across multiple fields including resource exploration, hydrology wells, coalbed methane extraction, shallow shale gas drilling, terrestrial heat projects, and coal-mine gas exploitation or salvage operations.

• Multi-functional Drilling: Supports various drilling processes including down-the-hole drilling, through-air reverse circulation drilling, gas lift reverse circulation drilling, cutting drilling, cone drilling, heel drilling, and core development. Can be equipped with mud pumps, foam pumps, and generators as per user requirements.
• High Work Efficiency: Full hydraulic and top drive rotary propulsion system suitable for multiple drilling processes and tools. Easy operation, flexibility, fast drilling speed, and minimal auxiliary time result in superior work efficiency.
• Low Operating Cost: DTH hammer drilling process dominates rock drilling operations, providing high efficiency and lower per-meter drilling costs.
• Enhanced Mobility: High-legged design facilitates easy loading and transportation without requiring cranes. Crawler tracks provide excellent mobility in muddy site conditions.

• Operators must receive comprehensive technical training, understand DTH structure principles and working performance, be familiar with safe operation and maintenance rules, and pass examinations before operating independently.
• All personnel must wear appropriate work clothes and safety helmets. Long hair should be securely tied and contained within head protection.
• During blasting operations, equipment must be retreated to safe distances and properly covered for protection.
• Conduct thorough equipment inspections before operation.
• Do not access slide frames during strong winds (above level 6) or freezing conditions. If necessary, use safety harnesses. Riding on slewing mechanisms or slide frames is strictly prohibited.
