 
ST200 crawler type water well drilling rig is a highly efficient and versatile drilling equipment and mainly used for drilling wells, agricultural irrigation wells, ground source heat pump wells and other wells, especially suitable for water intake projects in mountainous and rock formations. 
 
200m Hydraulic Crawler Mounted Drilling Rig Machine for Water WellIt can be used for drilling on different formations with a maximum diameter of up to 350 mm. The rig adopts new hydraulic technology, which is equipped with high-torque hydraulic motor rotation and large-diameter hydraulic cylinder propulsion.The independent module design allows the rig to be easily mounted on the truck for increased maneuverability. Two-speed swivel and propulsion speeds are available for different piercing needs in soil and rock formations.
