DescriptionParameter

1. The drill rig can drill different stratums, Max. borehole diameter achieves to 305 mm, Maximum depth 
comes to 
500 m when end diameter is 105mm.

 

2. The rig adopts the new type hydraulic technology, equipped with two rotary hydraulic motors with
high torque, Max. torque comes to 8000 N·m,
 highest output rotational speed is 52~135 rpm,6 grades to 
switch.

 

3. The rig has two large caliber high pressure cylinders, supplying the lifting power as much as 15t for the 
drill rig , ensure the drill rig have reliable propulsion and lifting force when drilling deep holes.

 

4. Six~cylinder turbocharged inter~cooled diesel engine by Famous brand provide abundant power for 
the hydraulic system, guaranteeing every part of hydraulic system to work efficiently.

 

5. Innovative embedded idler pulley structure, we increase the carriage stroke (maximum to install 4- meter 
drill pipe), very convenient for users to install and discharge pipes and the casings.

 

6. Four independent large diameter hydraulic jack cylinder (can load 5 tons), the drill rig can automatically
go up and down through hydraulic drive, the height can reach to 1.6 meters, easy for loading and unloading,
perfectly solve the user difficulty in equipment transportation.

 

7. The four leg cylinders can be individually controlled, convenient to adjust the vertical angle between 
wellhole and the ground when drilling, increasing the stability at work.
