ABSTRACT:
A tailgate locking mechanism is provided for locking the tailgate in a closed position against the rear end of the body of a rear loading refuse collection vehicle. The locking mechanism includes at least two fluid operated piston and cylinder locking assemblies, at least one of which is visible to the vehicle operator. Actuation of the piston and cylinder assemblies is sequenced so that the visible piston and cylinder assembly is extended only after the remote, or non-visible piston and cylinder assembly is extended, and is retracted only after the non-visible piston and cylinder assembly is retracted.
