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. For 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.
