Hooking up a trailer set to a Prime Mover is an important task to ensure safe operation of the vehicle, but more importantly to ensure safety to the driver and other road users and that freight is secure and not damaged. B-Doubles can be rated to carry up to 68 tonne of freight and single trailers up to 45 tonne, so its critical that trailers are hooked up properly.
If a hook up is not performed correctly, the trailer(s) may come adrift from the Prime Mover. This may happen instantaneously in the depot, out on the street or worse, out on the open road. Factors that contribute to incorrectly hooking up a trailer include:
- insufficient training;
- inadequate training;
- rushing; and
- equipment malfunction.
A heavy vehicle truck driver should develop a routine and always double check the important task of trailer hookup, each and every time. No matter whether the driver is relatively new or a 30 year veteran.
