Our standard arc-gate and bottom dump skips are well suited for almost any application. For specialized situations we also offer, sala, front dump and kimberley skips. NMT skips are fabricated in aluminum, steel and stainless steel or a combination of materials as needed. Our unique design for aluminum skips eliminates the common complaint of cracking welds which are often difficult to repair at remote sites. Corrosive environments and dissimilar metals are mitigated with experienced design, galvanic barriers and sacrificial anodes. Impact and wear are controlled with various rubber impact and high brinell liners.

Arc Gate Skip
  • Lowest maintenance of any skip type
  • No safety latches to maintain
  • Smooth, fast opening
  • Ideal for dry, crushed material
Bottom Dump Skip
  • Low maintenance workhorse of the mining industry
  • Quick change bucket design allows fast bucket change-out for minimal down time
  • Liners can be changed safely and conveniently away from the shaft
  • Ideal for wet, sticky, uncrushed material
Kimberly Skip
  • Low maintenance
  • Best payload to weight ratio
  • Slower dumping
  • Economical and ideal for smaller operations

Shaft - shaft steel

We have supplied shaft steel for major projects around the world for over 25 years. We are well known throughout the industry for our consistent high quality product.

NMT played an integral part in developing the first North American shaft steel installation to utilize cantilevered steel guide technology for high speed hoisting. This along with huckbolted steelwork increased flexibility in the guide string thus decreasing stress on the steel work and conveyances. Shaft maintenance was reduced and the life of the mine shaft and equipment extended significantly.

NMT further collaborated with industry experts to develop the bob-tail huckbolt to facilitate steel installation.
