The drill jumbo carriers are designed specifically for limestone mines and efficient drilling of headings as large as 50-60 ft. wide and 35 ft. high in one set up.

These self contained, diesel hydraulic jumbo drills provide the flexibility required to handle face, bench and roof bolt drilling requirements. Both models carry all fuel and pelletizing water necessary to operate a full 10 hour shift without service.
