The Joy Multibolter is an innovative addition to the Joy bolting product range. It is a multiple drill-head, platform-based, mobile bolter designed primarily for “place change” continuous miner applications. In addition, the outer roof bolters on the 3045 model can be rotated over to provide rib bolting.

The functional and ergonomic design, based on an operator-controlled adjustable-height platform, reduces costs and increases working space. The elimination of swinging booms and other moving parts reduces repair costs, enhances operator safety, and extends the unit’s operating life.

With its unique scissor lift arrangement, the Multibolter 3045 model handles a wide range of bolting heights. Platform extensions allow for a wide range of operating widths and also enable rib bolting. Also, the entire operator platform and guard rails extend sideways to fully reach the roadway edges. The Multibolter comes in four models, handling a wide range of seam heights.

Designed for maximum bolting versatility

  • Semi-automatic bolting for installing multiple bolts in a parallel operation, reducing cycle times
  • Operator-controlled platform level adjustments for varying localized seam conditions
  • Extendable side platforms for full-width bolting (3045 model)
  • Roll-over capabilities for outer bolters for a range of rib-bolting options
  • Wet- or dry-drill versions (with vacuum dust collection system)
  • Customizable number of platform-mounted drill units (2 roof/1 rib or 4 roof/2 rib)
  • for matching the designed bolting patterns for the prevailing mine conditions
