RCF220W Borehole Drilling Machine for Hydrology Wells Supplies
RCF220W Borehole Drilling Machine for Hydrology Wells Supplies
Machine Introduction
Our latest water well drilling rig adopts advanced hydraulic drive system, which is powerful, energy-saving and efficient. The maximum torque can reach 4700 Nm and the drilling depth exceeds 220 meters. The equipment is equipped with intelligent control system, which can accurately adjust the drilling angle to adapt to various complex working conditions. The main structure is made of special alloy steel, and the key components are treated with wear resistance to ensure long-term stable operation. The drilling rig is particularly suitable for geological exploration, hydrological monitoring, agricultural irrigation and civil water extraction, with the advantages of fast drilling speed, accurate positioning and low failure rate.

Machine Advantages
1. This rig adopts hydraulic system, large torque, high drilling efficiency.
2. The propulsion and lifting use hydraulic cylinders to drive the plate chain transmission, large power, strong torque, powerful drilling in soil, sand, hard rock and other complex geological conditions.
3. the tower assembly has a hydraulic compensation mechanism, the tower supported on the ground when drilling, with greater bearing capacity and higher stability.
4. The front outrigger adopts a telescopic structure, which has a large span during construction and high stability of the drilling rig.
5. this rig is hydraulic drive, mounted on four wheels, very convenient for moving and transportation.
