ZB21

  • Aisle navigation Inside 3 m up to 2.4 m bolting head Inside 10 ft. up to 8 ft. bolting head
  • Height with canopy in drill/tram position 2.8 m 7 ft. 3 in
  • Width overall 1.7 m 5 ft. 6 in

Excellent versatility in a small-class bolting platform

The innovative ZB21 offers convenience and productivity on a flexible common carrier platform. This solid workhorse allows completion of the bolting cycle from the operator enclosure to reduce human interaction with screens and bolts. Plus, the ZB21 can even be converted to a jumbo drill.

  • 100% of bolting cycle can be performed from the operator’s compartment
  • 2 of the major bolt types can be installed off a single carousel
  • 100% tunnel bolting coverage — floor, walls, backs, face

Features and benefits

Innovative bolting head

Limited moving mechanical parts and a simple design for smooth operability. Reduced bolting cycle times and increased drifter uptime helps you keep production moving.

Performance-boosting operator enclosure

Ergonomic, ISO-compliant and ROPS/FOPS-certified cabins or canopies. Optional enclosed cabin available with climate control.

Productive drifters

Exceptional consumable life with technologies designed to enhance drilling productivity. Drifter model options include the Komatsu JZD08, JZD10 and JZD12, manufactured by Montabert.

Screen handler and chemical injection system

Integrated screen handling allows full completion of bolting cycle from inside the operator enclosure. New chemical injection system provides superior alignment and accuracy and can help boost productivity with reduced bolting cycle times.

Common carrier design between ZB21 and ZJ21

New platform offers universal controls, outer boom structure, driveline and operator enclosure configurations. Designed to give your mining operation versatility while simplifying maintenance and training.

Superior coverage

Exceptional coverage for vertical and horizontal reach. Ideal for fitting into many smaller mine sections and can use a variety of bolt types: mechanical, friction, chemical and hydro expanding.
