Horizontal Directional Drilling Rig

Model: DRH-280H Powered by Cummins 132KW turbo charged diesel engine; Semi-automatic Rod Loader;

Salient Features

l Powered by Cummins 132KW turbo charged diesel engine, DRH-280H HDD drilling rig provides max. thrust/pullback force of 280KN, and a high torque of 10,000N.m.

l Semi-automatic Rod Loader can keep drill rod in its rod holder case and reduces the operators’ work density and increase the drilling efficiency.

l  Crawler base with rubber track, this ensures high mobility of the rig and makes it good for use on paved road

l Automatic stakedown system and rear end hydraulic support outriggers allows the operator easy to set the drilling rig balance and keep the drilling rig stable for operation on soft mud ground.

l Driving of the drilling rig on the road can be done through a cable remote control.

l The spindle movement for thrust and pullback is driven by 2 independent hydraulic motors installed on the rear end of the rack. Towed by steel chain on the slide rail, the spindle assembly can slide on the slide rail freely.

l The rotation of the spindle is driven by 4 independent hydraulic motors. This ensures high torque output in the spindle rotation. The spindle has a higher speed setting of 0-100rpm and lower speed setting of 0-56rpm.
