Abstract: A method of handling the removal and installation of a manway cover to a manway flange includes removing a plurality of cover bolts from a portion of the cover, providing a flange hinge plate of a portable cover hinge device with an aperture therethrough, inserting the first end of a fastening pin through the aperture and into an aligned bolt opening of the flange, where the pin first end has a bore transverse to the longitudinal axis of the pin, inserting a transverse rod into the bore of the pin, securing the flange hinge plate to the flange, inserting a first end of another fastening pin through the cover hinge plate aperture and into an aligned bolt opening in the cover and securing the cover hinge plate to the cover, pivotally connecting the flange hinge plate to the cover hinge plate, and removing any remaining cover bolts.

Abstract: A method of handling the removal and installation of a manway cover to a manway flange includes removing a plurality of manway cover bolts from a portion of the manway cover that is located to one side of a vertical axis of the manway cover, providing a flange hinge plate of a portable manway cover hinge device with at least one hinge plate aperture therethrough, aligning the at least one hinge aperture of the flange hinge plate with a bolt opening in the manway flange, inserting a pin first end of a hinge plate fastening pin through the at least one hinge aperture and into the aligned bolt opening in the manway flange where the pin first end has a bore transverse to the longitudinal axis of the pin and extending beyond the manway flange, inserting a transverse rod into the bore of the pin, securing the flange hinge plate to the manway flange, providing a cover hinge plate of a portable manway cover hinge device where the cover hinge plate has at least one hinge plate aperture therethrough, aligning the at le

Abstract: A removable cover support system and method for supporting a cover of a cover assembly having a cover support extension and a cover flange having cover flange holes has a cover flange securing base assembly having a base member and a securing mechanism slidably insertable through at least one of a cover flange hole of a cover assembly having a cover support extension and a cover flange, a retaining sleeve connected to the securing base assembly, a swingarm assembly rotatably supported by the retaining sleeve, and a lifting mechanism connected to the swingarm assembly. The securing mechanism is operably connected to the base member and the lifting mechanism is operably connected to the cover.

Abstract: A portable manway hinge device has a pair of hinge plates where each hinge plate has a support member with a hinge aperture positioned for alignment with a bolt opening of a manway cover and a manway flange, a linkage member adjacent a first end of each hinge plate and extending out of the plane of the hinge plate, and a pivotal connection coupling overlapping pairs of the linkage member of the pair of hinge plates.

Abstract: A portable manway hinge device has a pair of elongated hinge members where each hinge member has a pair of longitudinally-aligned, elongated apertures, a support member slidably connected to each of the elongated apertures where the support member has a pin receiving end, and a linkage member pivotally connected to each of the pair of elongated hinge members.

Abstract: A removable cover support system and method for supporting a cover of a cover assembly having a cover support extension and a cover flange having cover flange holes has a cover flange securing base assembly having a base member and a securing mechanism slidably insertable through at least one of a cover flange hole of a cover assembly having a cover support extension and a cover flange, a retaining sleeve connected to the securing base assembly, a swingarm assembly rotatably supported by the retaining sleeve, and a lifting mechanism connected to the swingarm assembly. The securing mechanism is operably connected to the base member and the lifting mechanism is operably connected to the cover.

Abstract: A method for portable lift, support, and/or installation is disclosed which permits and enables these various functions without the need for external crane/lift machinery. The method includes attaching a removable swingarm assembly around an object extension of a structure, inserting a swingarm into a swingarm sleeve on the removable swingarm assembly, positioning the swingarm wherein an object support assembly on the swingarm is adjacent a removable object, attaching the object support assembly to the removable object, disconnecting the removable object from the structure, and pivoting the swingarm causing the removable object to be moved away from the structure.
