Sheaves

Looking up at the massive sheaves at the Centennial #6.

Sheaves are wheels with a groove, intended to guide a rope. In this case, these sheaves are twice as tall as I am, mounted 100 feet about the ground at the top of the Centennial #6 rockhouse. Thick hoisting cable would run into the building from the hoist (behind me), over these sheaves, and then down the skip road into the shaft (down and to the front).
