High Torque Fast Penetration Pneumatic Crawler Drill 350m Depth For Farm Water Well

The ST 350 pneumatic crawler drill features a reasonable overall layout using tractor-mounted or full ground chassis for transportation with excellent maneuverability. Highly flexible in difficult terrain, this drilling rig is widely used in resource exploration for hydrology wells, coalbed methane, shallow layer shale gas, terrestrial heat applications, and coal-mine gas exploitation salvage work.

The top-mounted driving head principal shaft has a large drift diameter, making it suitable for various construction work including slurry drilling, air drilling, and air foam drilling. This versatility meets the demands for well-drilling across different terrain strata.

• LG140 speed regulation assembly with 10 speed ranges of automobile
• Large torque, strong bearing capacity with remote control and speed change capability
• High installed power with 2-gear reverse speed for effective accident handling
• Normally closed hydraulic chuck for easy operation
• Independent operation of vertical shaft and winch
• Large diameter vertical shaft through hole compatible with large hexagonal driving drill pipe

• Groundwater level of thick limestone is generally deep; shallow water levels indicate fractured zones and fault zones
• Thick marl generally requires good supply conditions with severe weathering and fragmentation for successful wells
• Dolomitic gray layers perform better in areas with longer seasonal spring periods
• Limestone mixed with shale provides better conditions when supply conditions are certain
• In limestone formations, water levels may not reach sufficient depth for continuous pumping without proper engineering
