## Narrative

At the shift change during the pre-shift inspection the hoist operator noted that while he was lowering the bucket on the surface it appeared that the brakes were intermittently stopping the lowering process. He called for the mechanic and the equipment superintendent, who was not immediately available. The 5-man crew in the shaft was told to stop work and evacuate.
