Product Details

surface drilling rig/rotary percussion drilling system

Product Description

Feature of surface drilling rig/rotary percussion drilling system

1) It is economical and efficient, mainly used in media and small-diameter pile civil construction;

2) Diesel engine has load induction and output power auto-control; the fuel consumption drops 5-10%;

3) 5-level anti-vibration technology absorbs drilling vibrational frequency all-directionally to guarantee high stability;

4) The special lubricating system makes sure that it can work under high-temperature environment;

5) The removable and symmetrical structure design doubles the service life of rotary drive key;

6) Crowd cylinder has two operation modes-normal lifting and fast lifting to improve push efficiency;

7) Optional chassis incline alarm enhances construction safety;

8) Mast verticality auto-adjusting technology promises the pile accuracy.
