OVERLOADING
Overloading is a very common occurrence that aggravates all of the above conditions that cause
tip-overs. Lufkin Trailers are designed to carry and dump legal loads.

SUSPENSION
Prior to dumping, the trailer suspension should be checked to make sure there are no broken
springs, damaged air bags, loose U-bolts, etc. Broken or weak springs should be replaced in
matched pairs.
