The original MacLean hard rock innovation.


The MacLean Advantage:

Designed to alleviate the negative aspects of hand held drilling and to improve drilling productivity, the Long Tom rig was the original MacLean equipment innovation for the hard rock mining industry.  Developed and marketed in the early 1970s, the drill rig has had over four decades of underground application under its belt, and remains in demand due to its simplicity and cost effectiveness.


Benefits:
  • Removes physical effort when: lifting drill, collaring hole, maintaining alignment, moving from hole to hole, changing steel
  • Drills a 1800mm hole in one pass
  • Eliminates air leg slippage
  • Eliminates hazards due to steel breakage
  • Unit drives to the face ready to drill
  • Simple air leg type maintenance

Features:
  • A cost effective solution that eliminates or reduces the following negative aspects of handheld drilling in trackless areas:
    -  Hard physical labour on uneven terrain
    -  High injury frequency, especially strains
    -  Low productivity with inexperienced crews
    -  Reduced pull due to hole misalignment
  • The Long Tom drilling system mounted on a rubber-tired mine carrier solves all the above problems and offers low maintenance costs, safe operation and increased drilling achievement per manshift
  • Rail mounted systems on application

Applications:
  • Sub-level development
  • Drawpoint development
  • Silling of stopes
  • Mechanized undercut & fill
  • Thin seam room & pillar
  • Cut & tight fill mining
  • Undercutting block caving
  • Broken, friable or slip filled drilling
