The Capacity of your Winding Engines

can be greatly increased by the use of Ferodo brake linings. The cages can
be raised at full speed to within a very short distance of the pit mouth and
pulled up smoothly and with certainty without the destructive practice of reversing
the engines. Ferodo fabrics have the highest co-efficient of friction, and
absorb more foot pounds of energy per square inch than any other material.
They are spark-proof, thus obviating any risk of fire. Their durability is many
times greater than that of hard oak, and they are at all times much more efficient.

If you have any braking troubles write us. Our twenty years’ experience in
the making of efficient braking surfaces is at your service.
