QY200A DTH drilling rig is an efficient and versatile drilling equipment. It is mainly suitable for drilling wells, agricultural irrigation wells, ground source heat pump wells and other wellbores. It is especially suitable for water intake projects in mountainous and rock formations. The drilling rig can be drilled in different formations, the maximum drilling diameter up to 350mm. The rig adopts the new hydraulic technology, supporting the rotation of the large torque hydraulic motor and the propulsion of the large-diameter hydraulic cylinder. The engine of the famous factory provides the power for the hydraulic system, the two-stage air filter and the intake air leading the compressed air to prolong the service life of the diesel engine. Unique pump design easy maintenance, reduce maintenance costs. Centralized control of the hydraulic console for easy operation. This series of rigs using excavator crawler chassis, off-road performance. Independent module design allows the rig to be conveniently mounted on a truck to increase mobility. Two-stage rotation and propulsion speed to meet the needs of different wear and tear in the soil and rock formations. Combined locator, according to different types of drill pipe and impactor to adjust the replacement of the positioning plate to ensure accurate and reliable positioning centering. Hoisting mechanism to facilitate the lifting of the drill pipe and the impactor, reducing labor intensity.
