Abstract

See full text

Dump truck bodies are mounted to truck frames by a hinge so the truck body can pivot about the hinge to eject a load from the truck body. Loads carried by these vehicles can be extreme and the cyclical stress can generate cracks in the hinges. An upper pivoting connection of a dump truck hinge has side members each with a mounting portion that join to the sides of rails of the body and a lower pivot portion. The upper hinge structure is pinned to a lower hinge portion on the truck chassis at the pivot portion. Bracing between the sides add strength to the pivoting connection.
