Pressurized closure assembly

1. A pressurized closure assembly, comprising:

a hub which is connectable to a pressure vessel, said hub having a central opening;

a head which engages said hub, said head movable between an opened and a closed position;

a davit positioned adjacent said hub and extending upwardly to a position above said head for engagement with said head;

a davit post mount near an end of said davit, said davit post mount receiving a davit post and supporting said head during movement between said opened and closed positions;

said davit pivotable about a substantially vertical axis;

a connector assembly disposed on a horizontal portion of said davit spaced from said vertical axis, said connector assembly having a clamping bar and at least one plate;

said connector assembly which is connectable to said davit to apply force for rotating said davit and said head, a bar connectable to said connector assembly at a first location and extending to a second location on an opposite side of said vertical axis.

2. The pressurized closure assembly of claim 1 , said head movable upwardly and downwardly by rotation of said head.

3. The pressurized closure assembly of claim 2 , said davit post mount and said davit post being threaded.

4. The pressurized closure assembly of claim 1 , said at least one plate having one of a connection aperture or a connection protuberance.

5. The pressurized closure assembly of claim 4 , wherein said one of a connection aperture or said connection protuberance having a geometric shape.

6. The pressurized closure assembly of claim 5 , said geometric shape comprising one of square, hexagonal, or octagonal.

7. The pressurized closure assembly of claim 5 , wherein said bar has the other of a connection aperture or said protuberance of a mating shape.

8. The pressurized closure assembly of claim 1 , said connector assembly being adjustable along said davit toward or away from said vertical pivot axis.

9. The pressurized closure assembly of claim 1 wherein said connector assembly is disposed at said davit post mount.

10. The pressurized closure assembly of claim 1 , wherein said plate has one of a connection aperture or a connection protuberance.
