ABSTRACT:
A system is disclosed for positively sealing the tailgate of a liquid or solid refuse collection body. The invention has special utility for vacuum containers in which a compressible seal surrounds the perimeter of the tailgate. The tailgate includes hooks having cam surfaces and the container includes rollers adapted for engaging the hooks and drawing the tailgate into positive engagement with the opening of the body. Hydraulic means are preferably provided for activating the rollers. If separate hydraulic means are employed for raising and lowering the tailgate, sequencing controls may be provided to permit locking the tailgate only after the tailgate hooks have been lowered to a position adjacent to the rollers.
