## Narrative

Schindler changed out the four roller guide assemblies on the Miracle Run elevator, upon returning to service after the install there was enough side movement for the safety dogs to grab and set, resulting in an entrapment of 3 miners at the top of the shaft for approximately 35 minutes until the safety dogs could be reset.
