Log trailer stake failures should be discovered through daily pre-trip inspections

Safety Alert Type: 
Heavy Equipment
Location: 
Ladysmith dryland sort (Vancouver Island)
Date of Incident / Close Call: 
2012-01-17
Company Name: 
Aljaq Contracting Ltd.
Details of Incident / Close Call: 

A Front End loader had just started to unload a logging truck when the front passenger side stake fell over, causing wood to fall off the truck. After the load had been removed from the truck the stake was inspected by the truck driver.

The cause of failure was a broken stake cable that had broke near the anchor point and appeared to be quite “rotten”. The truck driver was not sure when the stake cables had last been replaced.

Learnings and Suggestions: 

Logging truck drivers need to perform more thorough pre-trip inspections on their stakes and stake cables and bunks that meet the requirements of:

WSBC Regulation 26.66 (8) - Stake and bunk assemblies must be inspected daily, and must not be used if they show signs of excessive wear

and

WSBC Regulation 15.25 - Wire rope rejection criteria

This is the third stake failure incident in the last two years at the Ladysmith Dryland sort. Two of them were broken stake cables and one was a broken weld on a stake. In all three incidents a more thorough pre-trip inspection should have uncovered the defective equipment.

With these trucks travelling on public roads and in close proximity to second loaders, scalers and the general public there is a huge potential for one of these failures to result in serious injury or death.
