The QY200 crawler type water well drilling rig is a highly efficient and versatile drilling equipment. It is mainly used for drilling wells, agricultural irrigation wells, ground source heat pump wells and other wells. It is especially suitable for water intake projects in mountainous and rock formations. The rig 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 famous engine provides power for the hydraulic system, two-stage air filter and the intake air design of the compressed air to extend the service life of the diesel engine. The unique pump set is designed for easy maintenance and reduced maintenance costs. Centralized control of the hydraulic console for easy operation. This series of rigs use excavator crawler chassis for off-road performance. 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. The combined positioner can adjust and replace the positioning plate according to different types of drill pipe and impactor to ensure accurate and reliable positioning and centering. The hoisting mechanism facilitates the lifting of the drill pipe and the impactor, reducing labor intensity.
