A lifting and transporting device for lifting a load and transporting the same transversely to the lifting direction. The lifting and transporting device being for use in manufacturing a screwed flange connection. The lifting and transporting device having a frame for picking up and lifting a load, a holder for holding the load and comprising a hoist for lifting and lowering the holder with the load attached thereto, includes a tensile anchor which is operatively connected with the bolting tool and in a state of the lifting and transporting device mounted on a flange can releasably be connected with the flange or with at least one screw bolt connection and is designed to limit the lift-off path of the bolting tool in the hoisting direction to a specified amount in the case of a fracture of the screw bolt connection to be pretensioned or of the connection of the bolting tool with the screw bolt connection to be pretensioned during the pretensioning of this screw bolt connection.
