Wagner loses wheel assembly while moving log bundles

Safety Alert Type: 
Heavy Equipment
Location: 
Northwest Bay log sort (Parksville, BC area)
Date of Incident / Close Call: 
2013-01-10
Company Name: 
Island Timberlands
Details of Incident / Close Call: 

The operator of a Wagner L120 had picked up two bundles of logs weighing approximately 57 tons.

While backing down the ballasted portion of the causeway to drop the bundles into the water, the left side dual wheels - complete with hub, brakes and axle - separated from the main frame of the machine (see photo on page two of the attached pdf).

Why? The L120 Wagner (with 20,000 hours) was inspected for fatigue and cracks in November 2012. There were no cracks observed at that time. Cracks with rust were noted on two surfaces after the failure, indicating they had been there for some time but had not been visible upon inspection.

Learnings and Suggestions: 
  1. Annual inspection to be done with a mag particle test, with wheels and guards removed. This will provide better access for checking the components and main frame assembly on the machine.
  2. Share the safety alert with other companies using this machine to warn of the possibility of this occurrence.
