Product Description

Portable RCF220W Borehole Drilling Machine with 1.4T Winch Hoisting Force

 

Machine Introduction
 

The optimal impact efficiency of each impactor has its matching optimal shaft pressure and speed. During the drilling process, as the number of drill pipes increases, the axial pressure on the impactor also increases. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more suitable axial pressure. At this time, the impact efficiency is higher.

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.
