ABSTRACT:
A dump truck spreads material to form a layer of material to form a structure such as a road by tilting a dump body pivoted on the truck and allowing a tailgate to open a gap through which the material flows as the dump truck moves forward. Typically, a pair of chains determine the width of the gap. In order to release the chains and allow the tailgate to swing freely if the material becomes jammed and does not freely flow through the gap, a pair of toggle-type chain releases are provided. The toggle-type chain releases comprise chain-retaining plates with slots therein for receiving one link of the chains. The retaining plates are rotatable from a chain-retaining position to a chain-releasing position. The toggles which operate the chain retaining plates include levers which are unitary with one link of the toggles and serve as operating handles which when pulled releases the chains.
