Electro-Hydraulic Step Drilling Rig

The bored pile drilling rig is introduced as below:

 Advantages

1.Crawling mechanism and walking mechanism can be ex-changed.

2.The column can be adjusted from two sides to ensure verticality of the drilling hole.

3.Drilling and piling at the same time. Improves the efficiency of drilling holes and shortens the time of the project..

4. No noise, no vibration, no pollution and good quality of drilling holes.

5. Accuracy and convenience in position by up and down the column.

6.Operation systems like electronic system, hydraulic system, monitor system are all gathered in the operation room for comfortable and convenient operation..

  Structure design

1. The column is foldable. The complete appliance can attached with towing device to be transported from different construction sites.

2. The power head system uses three-ring  reducer mechanism, with great weight bearing capacity, and reliable in use.

3. The side adjustment mechanism can work independently to adjust the verticality of the column.

4. Spiral vane of the drilling rod uses high quality carbon steel 16Mn, which is hard-wearing, good in strength. The bit inlays carbide blades to drill faster than normal.

5. The main windlass uses reducer with greater reduction ratio, which is simple in structure but good in the rope-arranging work.
