H225DB Helicopter Drilling Rig

 

H225DB Helicopter drilling rig is powered by AC VFD, and the drawworks, rotary table and mud pump are independently driven by AC motor respectively. It can be fitted with a top drive system. The rig (including main unit and unitized equipment) is composed of approximately 90 transportation modules, and each module does not weight more than 10t (22000lbs).

• The drawworks, rotary table and mud pump are separately powered by VF motor.

• K-type swing-up mast, installed in low position and raised as a whole.

• Modularized foldable drill floor.

• Modules are connected with standard pins, and can be conveniently.

• dismantled and assembled using special pin-removing tools.
