Image Showing Failed Fifth Wheel

We performed a forensic investigation on a fifth-wheel failure which caused separation of a trailer from its tractor.

It was determined that one of the major causes of the fifth-wheel failure was due to lack of maintenance and lubrication. The condition of the fifth wheel on the day of the accident made hooking up and locking the trailer to the truck unreasonably difficult, increasing the chance of a partial hookup.

We have investigated a number of Fifth Wheel accidents – as well as other types of trucking accidents.
