Log strikes forwarder cab

Safety Alert Type:

Company Name:

Details of Incident / Close Call: 

While loading logs with a forwarder grapple in steep terrain, a log on top of the bunk was crossed up.

The machine jerked while clearing the haul track, causing the log to slide over the headboard, hit the windshield and slide right through the cab and out the back window, narrowly missing the operator.

Learnings and Suggestions: 
  • Main cause: a crossed up log on top of the load that slipped over the top of the cab guard
  • Operator must take care loading logs, ensuring that all logs are located beneath cab guard
  • Review harvesting system – i.e. shovel or grapple stems to a safer location to process and then forward logs to skid
  • Cab window failed safety specification – it did not withstand impact of log. This needs reviewing / modification.
