1. Handling gear for a catalyser cage with a flat, rigid supporting frame which has a rectangular basic shape and which has in the region of its corners at least four holding bolts for suspending the catalyser cage, which bolts can be displaced outwards and secured beyond the limits of the supporting frame, and on the upper side of which frame a suspension device for lifting apparatus is located in the region of the axis through its centre of gravity, which is perpendicular to the plane of the supporting frame, characterized in that the holding bolts (2) are each allocated in pairs to a toggle lever system (toggle levers 4a, 4b) by which they can be brought into the holding position, the two toggle lever systems (toggle levers 4a, 4b) being operated by two push rods (5a, 5b) articulated on the ends of a two armed operating lever (6) which is mounted rotatably in the supporting frame (1), and in that the push rods (5a, 5b) and toggle levers (4a, 4b) do not project beyond the limits of the supporting frame (1) during their operating movements. |
