EVANGEL supply borehole rig application of drilling machine

Feature of  EVANGEL supply borehole rig application of drilling machine

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.
