DRILL RIG KELLY BAR ROPES
The Kelly winch allows for the adjustment of drilling pressure by controlling the force applied to the Kelly bar. The wire ropes for this application are usually subject to rotational forces from the spinning kelly bar, shock loading from always changing drilling conditions, and less than subtle movements from new operators.
That is why Teufelberger utilizes a more shock load resistant design made up of 4 large inner strands rather than an additional layer of smaller strands as you would find on a tower crane for example. Additionally, there is a layer of plastic between the inner and outer layer to act as a cushion for the wires between the inner and outer strands.
