The stellie hoist of the trolley is lowered. If the lower arms of the pliers shank 11 "of each block 20 the holding-down stamps 6 of the corresponding stripping pliers 5 are given away with pins IS, while their perwerkes 4 hit the highest of the molds, then upper arms Hb have rollers 16, which in one become the Siripperwerkträger 3 further lowered, control traverse 17 are guided. The control traverses while the strip 17, which is seated on the mold, is attached to the lower stripper mechanism housings 7 in a fixed manner relative to the stripper mechanism carrier. The lower stripper mechanism housing 7 every 25 then meets the hold-down stamp of the second stripper mechanism is opposite the upper stripper stripper mechanism on the second highest mold, then mechanism housing 8 with regard to the creation of this process is repeated analogously until the tong legs Ha, 11b on the block 9 and the hold-down ram 6 of all stripping mechanisms 4 rest on the pulling of the block by a certain amount of displacement- associated molds 10, which is borrowed by the. In the lower stripper mechanism housing 7, each independent, displaceable mounting of the individual stripper mechanism is enabled relative to this stripper mechanism 4 which cannot be displaced.

The upper stripper housing 8, which can be fitted with a stripper mechanism housing 7, is displaced opposite the upper collar on the stripper mechanism support 3. As a result, the stripper mechanism housing 8 of each stripper mechanism 4 is raised into the control traverses 17, and the blocks of the traverse clamped vertically by a certain amount close in the usual way,

The invention relates to a multiple that is used in stripper cranes, i. H. Single stripper stripper for stripping several, is known, between the stripper and upwardly widening blocks from on a 40 the stripper work support damping organs to form a cast plate standing molds, with a mean. These damping organs have the task there seeds that can be raised and lowered with a sudden block release several, each assigned to a mold, to prevent the stripping unit from being thrown upwards perwork with hold-down stamps and their own or the falling movement of the (lifted) strip drive. 45 perwerkes after slack rope formation and slipping

With such a known multiple stripping front of the pliers to dampen from an obstacle,
direction, two stripper plants each have a. In a further advantageous embodiment of the invention

Hold-down stamp with stamp and displacement are common to the stripper works by means of time relays. As a result, the inner ones are mutually switchable. This measure prevents the hold-down ram 50 arranged in a row from simultaneously releasing the blocks to be stripped from the multiple stripping with their foot pieces onto the upper edge cutting device, and two adjacent molds open. Since the upper edges of the upward movement of the individual stripper works standing on the casting plate, which arise one after the other in the block solution, is usually molds - due to e.g. B. aurch transferred more gently to the stripper work carrier than the molds occurring manufacturing accuracy 55 with a simultaneous block solution. The stripper - not all of them lie in one level and the work girders therefore also hang more quietly on the crane hold-down ram, consequently with the known hooks or in the Hubscil bottles.
