A new level of adaptability and capability

The new Komatsu ZB31 Mechanized Bolting rig features a common platform design that helps increase user adoption and makes training more efficient.

Discover a new way to bolt

The optional pumpable resin system for bolters featuring J-LOK P by JENNMAR offers an alternative to using expensive, limited bolt types. This system leverages all the advantages of bulk resin systems and expands your bolting hardware options to include low-cost rebar — an industry first.

Features and Benefits

Bolter-ZB31-San Xavier Mine AZ-DS-240807-KOM-4357.jpg

Product commonality

With a focus on modularity, the Z3 product line shares common parts and placement for systems, including driveline, hydraulic and electrical. It greatly simplifies user adoption via operator and maintenance training. Streamlines inventory planning and spare parts management too. The bolting head also has double feeds and comes standard with 2 top hammer drills, which share 100% of parts.

ROPS/FOPS-certified operator enclosure

Newly designed, fully enclosed operator cabin meets ISO safety and ergonomics standards. Exceptional noise and vibration reduction, air cleanliness and visibility deliver outstanding operator comfort that promotes efficiency. Open compartment available with telescoping canopy.

Light and durable bolting heads with Komatsu drifters

Cast polymer components reduce weight and improve longevity. Komatsu drifters — manufactured by Montabert — deliver excellent power at the bit and extended consumable life via shockwave transfer technology.

Diesel power

Diesel power engine designed for the rigors of hard rock mining. Our diesel offering includes both Tier III and Euro V Cummins engines to meet the local regulatory requirements of our underground hard rock customers.

Simple, reliable, industry-proven pilot hydraulics

Intuitive, user-friendly controls allow the operator to perform multiple controls simultaneously, thus fast-tracking your bolting cycle. Maintenance and diagnostics simplified through a clean and clear hydraulic design.

Bolter-ZB31-San Xavier Mine AZ-DS-240807-KOM-4378.jpg

Flexibility for varying bolting applications

Komatsu bolting heads accommodate multiple bolt lengths and types. Allows the installation of all four major types of rock bolts: friction, hydro-expanding, mechanical and chemical bolts.

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.
