What Rope is Best for You?

By working with customers in the mining industry, the company has been able to provide products and technical assistance for some of the most difficult and complex hoist installations in the world. Northern Strands offer a full line of wire ropes, regardless of the hoist setup or stage of the mine development.

Wire Ropes for Mining

We have supplied wire ropes for Ground and Tower Mounted Friction (Koepe) Hoists, Drum Hoists, and Blair Hoists. When choosing a wire rope for your hoist, keep in mind that no wire rope can do it all. There are many factors to consider:
  • Resistance to Drum Crushing
  • Resistance to Rotation
  • Strength (also known as minimum breaking force)
  • Resistance to Fatigue Wear
  • Corrosion Resistance
  • Service Life
  • Rope Flexibility
  • Rope Diameter
  • Weight per foot
  • and the list goes on
As you can see, it is not a simple task, so Northern Strands can help assess the situation and provide a rope solution that best suits your needs.


Sinking Ropes

For Sinking ropes, a rotation resistant rope is required. As the shaft gets deeper, the resistance to rotation becomes critical, so we can help design a rope that will perform as expected or better.
