MARMOROK NK200 ECO
We started to our first innovative design and manufacturing process of top hammer drill rig for marble quarries with prototype of Marmorok CTR on 2011. Rig tested along with the toughest climate fields by our respectful designers and drillers. After design improvements Marmorok CTR forge ahead to become a leader on it’s field, with increased efficiency and high standard safety. Rig allows drillers and offsiders easy to operate and service environment to reduce downtime and provides top level of productivity by secure and fast drilling.
|Machine can achieve depths approaching 12 meters (39,4 ft) depth (Drill Hole : Ø 70 mm with T38 (1 ½”) Guide Tube – T38 (1 ½”) Guide Rod) in good conditions and capable of drilling from vertical to horizontal and also inclined.
