The present invention consists of a lifting tool (1) for internally flanged bodies comprising: a body (8) consisting of a solid supporting structure; means (19) to ensure the rotation of a lever (10); means (10) for moving rods (9): these means consist of a lever (10) placed in rotation on the pin (19) by at least one hydraulic cylinder (14), which is connected to said lever (10) by means of a hinge (13) and to said body (8) by means of a hinge (11); means (14) for moving the lever (10); means (9) for pushing petals (5) radially outwards: these means consist of a rod (9) for each petal (5): said rods (9) are connected to the lever (10) by means of hinges (12) and to the petals (5) by means of hinges (20); means (5) to ensure the centering of the body (8) with respect to the pipe (2); to also ensure the lifting of said pipe (2) by engaging the flange (3), welded to the pipe (2): such means consist of at least three petals (5), constrained in movement by at least one sliding block (16) for each petal (5): each such sliding block (16) being slidable in a guiding slot (15) machined into the body of the petal (5); means (16) to ensure the radial movement of the petal (5) with respect to the geometric axis of the body (8); these means consist of at least one sliding block (16) for each petal (5) : each such sliding block (16) being slidable relative to the petal (5) in a guiding slot (15) machined into the body of the petal (5) itself; means (6) to ensure that during the lifting of the petals (5) the petals (5) do not leave their seat; these means consist of supports (6) able to counteract the upward force that is generated on the back of the petal (5) during the lifting operation.
