Product Description ： Choosing the YGQZ-400 pneumatic water well drilling rig offers an ideal balance of drilling depth, investment cost, and operational efficiency. With a maximum drilling depth of 400 meters, this model meets requirements for medium-to-deep wells—including those for domestic water supply, agricultural irrigation, small-scale geothermal applications, and exploratory drilling. Equipped with a high-torque power head and a renowned diesel engine, the rig delivers robust power; it also offers optional pneumatic impact or mud circulation systems, enabling it to easily handle diverse geological formations such as clay, sand, gravel, and hard rock.
Product Features： 1. User-Friendly Design: Featuring a unique cam design and a centralized control operating system, the rig is easy to maintain and operate, providing convenience for machine handling. 2. High Mobility: The rig uses a crawler chassis similar to that of an excavator, offering excellent off-road performance. It can also be mounted on a truck for enhanced mobility. 3. Efficient in Soil and Rock: Dual gear rotation and feeding speed allow the rig to operate effectively in both soil and rock layers. 4. Dual System Options: The rig can be equipped with two optional systems: 1) Air power system with an air compressor; 2) Mud pump system with a mud pump.
