Winding ropes

The winding ropes used at both shafts were originally of the stranded variety. When the South shaft was upgraded in 1900, the same type of rope was again used but, due to the tendency of the ropes to twist, problems were soon encountered with the cages coming into contact as they passed each other.  Various alternative types of rope were tried before the (expensive) locked-coil rope eventually eliminated the problem.  There had never been a problem in the North shaft since the solid guides used there prevented the cages from twisting. After the South shaft was deepened in 1921 rail guides were installed there but by then the use of locked coil rope for winding had become standard.

North  pit winding rope detail circa 1904 (FoPP/JST).    This appears to be a 6 strand right-hand lay rope. The resolution is inadequate to determine whether it’s Langs or Ordinary lay.
