The ST-300 fully hydraulic drilling rig is a multifunctional machine primarily used in construction, highway, bridge, water conservancy, hydroelectricity, mine, and tunnel applications. It is widely employed for engineering hole construction including foundation investigation holes, deep foundation pile anchor holes, road or dam foundation reinforcement holes, drain holes, open pit blast holes, water wells, and foundation piles.

• High detachability for easy transportation
• Suitable for operations in both plains and mountain areas

• Coal mine, ore mine, energy industry, and water well drilling
• Investigation and geophysical exploration
• Highway and building construction
• Blast-hole drilling and foundation work
• Close lever design for convenient, safe, and reliable operation
• Easy operation and durable construction saves labor and costs

The center of gravity of the water well drilling rig must be balanced according to road conditions and site requirements. Random drilling is prohibited at construction sites. Proper signage must be displayed for backfilled pits and pools. In narrow roads or dangerous sections, lower the mast and retract the crawler. Adjust the mast's lifting angle and left-right inclination in inclined sections, and adjust the rig's center of gravity by turning on the truck. When encountering water on access roads or construction sites, use the drill pipe bit to guide the machine.
