2009-10-19 Log Truck Incident - Broken Trailer Reach

Safety Alert Type: 
Log Hauling
Englewood Forest Operation
Date of Incident / Close Call: 
Company Name: 
Western Forest Products
Details of Incident / Close Call: 


A loaded highway log truck, under normal operating conditions, was travelling up a slight adverse and approaching a right hand corner. As the truck entered the corner, the back of the trailer reach failed and the trailer swung out to the left side. The driver was able to safely stop the truck with the load intact; the loader arrived and removed the logs.
The trailer was an 11 year old Tridem. It was determined the area of the trailer reach that failed was hidden from plain view inside the square tubing of the main trailer body, underneath the rear bunk. The location of the crack was where manufactured holes had been cut for the trailer reach anchor pin to pass through. Evidence identified where the reach failed was ½ from a previous crack and ½ from a new crack.
The current inspection process does not indicate the trailer reach should be pulled out of the square tube to inspect hidden wear or stress points.


Learnings and Suggestions: 


1. If previously not completed, immediately inspect Tridem log truck trailers for cracks, where the reach is hidden from view inside the square tubing of the main trailer body, underneath the rear bunk.
2. Add trailer reach to the annual inspection checklist. Ensure the trailer reach is pulled out of the rear bunk trailer tubing far enough for a full inspection of the concealed portion. Especially where the anchor pin holes are located.
