## Narrative

The hoist kicked the breaker 4' from the bottom as it was traveling down. While resetting power, employee attempted to jog the hoist before the system powered up. The PLC was not aware oil was still in the system, which prevented the brakes from properly setting and caused the hoist to drop to the bottom of the shaft. When the hoist dropped, three guide wheels were damaged.
