145ton deep water drilling rigs drilling machine types sr380

Feature of   145ton deep water drilling rigs drilling machine types sr380 

 

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.
