Hinged Derails for Mines

Nolan's HDM mine derail

Nolan manufactures two sizes of hinged derails for use in mines. The HDM-60 and the HDM-85 are fabricated from tough carbon steel.

  • Two-way design allows protection from approaching or retreating equipment.
  • Low-profile design keeps the derail just 2-5/8” above the top of the rail.
  • Innovative design bolts to an existing joint/splice bar bolt holes.
  • Unit is hinged for easy use and performance.
  • Ergonomic handle allows easier, more secure grip when placing derail on or off the rail head.
  • Reflective material on the ends of the derail block adds safety by improving visibility of the derail.
