Lifting and transporting device

A lifting and transporting device for lifting a load and transporting the load transversely to a lifting direction, for use in manufacturing a screwed flange connection in order to bring a bolting tool into a bolting position in which it is in engagement with a screw bolt connection to be pretensioned or to be released, or into a transport position in which it is out of engagement with a screw bolt connection and can be transported to a next screw bolt connection, wherein a flange extends horizontally, the lifting and transporting device comprising:

• a frame configured to pick up and lift a load, wherein the frame extends around a load space of specified size;
• and
• a holder configured to hold the load, wherein the holder is movable relative to the frame in the lifting direction,
• wherein the holder comprises a hoist that is attached to the frame beside or adjacent the load space and is configured to lift and lower the holder with a load attached thereto,
• wherein the frame is mounted on a first support bearing and a second support bearing, whose support directions each extend perpendicularly to a transport direction and at a specified angle to each other, and which both in the lifting direction and perpendicularly to the transport direction and to the lifting direction have a distance to each other,
• wherein the first support bearing is designed for abutment against an upper side of the flange between a screw bolt connection and a flange edge and the second support bearing is designed for abutment above the screw bolt connection against a component wall extending from the flange, and
• wherein a tensile anchor 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 adjacent to the screw bolt connection to be pretensioned and is designed to limit a lift-off path of the bolting tool in a hoisting direction to a specified amount in a 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 pretension of this screw bolt connection.
