Products Description
The RCJ350D pneumatic DTH drilling rig is a versatile water well drilling machine that combines both water and air drilling capabilities. It has a 525 vehicle gearbox, allowing for quick and easy gear shifting. Compared to hydraulic transmission, the pneumatic system offers twice the transmission efficiency and reduces power consumption by 35%, making it more energy-efficient. The pneumatic DTH drilling rig effectively addresses challenges in drilling with an air DTH hammer in soil layers and improves construction efficiency when dealing with hard rock, gravel, and pebble layers, where rotary drilling rigs typically struggle.

Products features
Speed and Torque: The RCJ350D pneumatic DTH drilling rig can achieve a rotational speed range of 50-1020 r/min, with a maximum output torque of 10,500 N.m, allowing it to handle a variety of drilling operations.
Efficiency Mechanism: It is equipped with a long-stroke double-speed mechanism and a mechanical power head with a 3500mm stroke, enhancing drilling efficiency and reducing the risks of drill blocking and burning.
Dual Oil Pumps: The RCJ350D pneumatic DTH drilling rig uses a dual oil pump system. A single pump is employed during drilling, and both pumps work in tandem during the lifting and lowering of the drill, minimizing power loss and shortening auxiliary time.
Crawler Chassis: The crawler chassis includes a 1.5m stroke outrigger oil cylinder, making it easier to load onto a vehicle and facilitating quick relocation and transportation.
Expandable Hydraulic System: The hydraulic system has reserved functional interfaces for future expansion, allowing customization based on the user's specific technological needs.
Collapsible Auxiliary Tower: This feature enables the lifting of two 3-meter drill pipes simultaneously, enhancing operational efficiency.
Packaging & Shipping
