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.
