ST 300 Borehole Drilling Rig Machine Advantages:

1.This is a mature of efficient and versatile hydraulic rig. It is mainly applicable to the drilling process of wells, monitor boreholes, and geothermal boreholes.
2.When drilling in the rock layer, the rig adopts DTH percussive hammer for penetration and compressed air for cleaning, with a penetration speed being dozens of times quicker than conventional rotation rigs.
3.Hydraulic supporters facilitate the rig erection on site without crane.
4.Smaller size makes it adaptable to various kinds of construction sites.

ST 300 Borehole Drilling Rig Machine Applications:

Widely used in industrial and agricultural water conservancy projects, test wells, and another exploration drilling. In particular, geothermal heating drilling can also meet various projects of engineering foundation reinforcement, loose gravel drilling, and rock formation connection.
Our drilling rigs are more efficient, have lower failure rates, are more economical and durable, and have comprehensive cost-effectiveness.

How can we do a good job in the maintenance of well drilling rig?

1. Pay attention to check whether the bolts and nuts of water and gas pipelines and various accessories of the drilling rig are firm at any time

2. . Always check the lubricating oil condition of the wind motor

3. . When the working face is immersed in water, a large-diameter drill head shall be used to insert the drill pipe when opening the hole, so that the drill pipe is 1-2 meters above the water surface to prevent mud and rock slag from falling into the hole
