Abstract
A lifting apparatus includes: a plate having multiple arms extending outward from a center thereof, each arm for engaging a respective portion of a support ring of a fuel tank; and multiple clips, each rotatably mounted on a respective arm. The clips rotate from an unlatched position to a latched position to secure the plate to the support ring of the fuel tank. A swivel device is rotatably mounted on the plate. Each arm has a ledge lowered from an upper surface of the plate for contact engagement with the bottom side of the support ring. Each ledge is sunken or lowered from the upper surface of the plate by a respective shoulder, such that the ledges and shoulders register and stabilize engagement of the plate with the support ring. The clips snap into the latched and unlatched positions and are automatically maintained there until rotated intentionally by hand by a user.
