There have been two recent incidents where trailer lifting chains failed while a trailer was being lifted onto the truck, including one near miss that could have resulted in serious harm, says the Log Transport Safety Council (LTSC).  

Following these events, the LTSC has reviewed these incidents, with the support of Maritime NZ and WorkSafe NZ, including a review of the Trailer Lifting Code. 

Both failures were attributed to worn componentry and poor maintenance. In response, the LTSC has produced a safety video explaining the causes of the failures and providing clear guidance on how to inspect and maintain trailer lifting chains. The recommended approach includes daily checks by drivers, along with monthly and annual inspections of the lifting chains and mounting points by a suitably qualified person.

The LTSC has also recommended an increase in chain and coupling strength to avoid further issues and significantly increase the system’s safety margin. This also serves as a reminder that trucks must carry a current trailer lifting certificate. 

The LTSC has requested that forest owners ask their trucking contractors to verify that certificates are up to date and reinforce the importance of regular inspections and maintenance. For further information, visit the LTSC website at:  https://logtruck.co.nz/ or see the video at: See more.
