## Narrative

The secondary counterweight inadvertently disconnected from the primary counterweight on the North side, which caused the South side chain to break.  This allowed the secondary counterweight to fall to the bottom of the shaft and prevent operation of the hoist.  The hoist and its structural components were not damaged from this occurrence.
