Komatsu’s new jumbo drill (left) and bolter (right) utilize a common platform that allows operators to convert their machine from a jumbo to a bolter, and vice versa.
Komatsu introduces a new jumbo drill and bolter that utilize a groundbreaking common carrier and control system for underground hard rock mining designed to meet the industry’s needs for greater productivity and versatility while helping lower capital costs.
Developed through extensive research and collaboration with their customers, the new small-class ZJ21 jumbo drill and ZB21 bolter utilize a common platform that allows operators to convert their machine from a jumbo to a bolter, or vice versa. The platform offers 100 percent design commonality between bolter and jumbo from the rear skirt to the outer boom structure, making for a seamless conversion.
The versatility provided by the common platform was created to help mining operations realize advantages in job site efficiency and — with the common parts, service and maintenance — help reduce costs. In addition, operator controls are universal between the jumbo and the bolter, to benefit mining organizations from a user training and adoption perspective.
The ZJ21 jumbo drill is designed to provide excellent coverage in a small jumbo platform, delivering up to 66 square meters of face coverage. The unique boom design promotes zero contact with the operator's enclosure or the carrier or leveling jacks when drilling anywhere on the face.
The ZB21 bolter enables operators to bolt in any direction, and is capable of handling up to an 8-foot bolting head. Operators can perform 100 percent of the bolting cycle from inside the enclosure using our integrated screen handler and innovative chemical injection system, helping mining operations drive toward zero harm.
