Patent ID: 11731223

Abstract:
In a lifting and transporting device for lifting a load and transporting the load transversely to the 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 tightened or to be released, or into a transport position in which it can be moved out of engagement with a screw bolt connection and can be transported to the next screw bolt connection, wherein the flange extends horizontally in the transport direction, comprising a frame which extends around a load space of specified size for picking up and lifting a load, a holding mechanism for holding the load, wherein the holding mechanism is movable relative to the frame in the lifting direction, and comprising a hoisting device which beside the load space is attached to the frame and is adapted for lifting and lowering the holding mechanism with a load attached thereto, wherein the frame is mounted on a first and a second support bearing whose supporting directions each extend perpendicularly to the transport direction and which have a distance to each other perpendicularly to the transport direction, wherein the first support bearing is designed for abutment against the flange upper side, and wherein at least the first support bearing includes sliding members or rollers which can be shifted or rolled off in the transport direction, the frame includes a first frame portion and a second frame portion, wherein the second frame portion is pivotally mounted on the first frame portion about an axis which extends in the transport direction, the first support bearing is attached to the first frame portion, the holding mechanism is mounted on the second frame portion so as to be shiftable in the lifting direction and is non-pivotably mounted with respect to the second frame portion about an axis extending in the transport direction, and the holding mechanism is configured to non-pivotably hold the load with respect to the holding mechanism about an axis extending in the transport direction.
