Transport firms are reminded by the Transport Agency to check their tow-eye coupling systems thoroughly, following recent incidents where the trailer has separated from the vehicle after the bolt-in tow eye system failed.
Given the significant safety risk posed by tow-eye coupling systems failing of late, the NZTA says it is investigating the use of these and may consider phasing them out.
According to NZTA if the tow-eye has not been correctly installed or maintained it can become worn, causing it to pull out of the drawbar.
With these systems, tightening up coupling bolts which have come loose will not solve the problem, and the unit needs replacing says NZTA.
It recommends that every operator carefully reads and adheres to the instructions issued by the coupling manufacturer.
Checking the security and quality of the trailer coupling should be a part of the daily walk-around inspection says NZTA.
