Abstract
A door sealing system is used to seal a container of a vacuum system. In a preferred embodiment the vacuum system has a container door supported on a frame and adapted to seal the container when the container door is closed. A latch assembly supported on the container door is used to latch the container door to the container along a load bearing axis. A power operated pulling assembly located within the container forces the container door against the container by applying a load on the door that is collinear with the load bearing axis of the latch assembly. The power operated pulling assembly seals the container door to the container. The mechanical locking assembly is adapted to maintain the door in a sealed configuration after the power operated pulling assembly has sealed the container.
