When picking up at least one layer of several devices, the two types of devices have in common that they only pick up the adjacent rows of shaped stones in front of the device and grapple stones from above, which cannot move the rows of stones away, which hinders the quick removal of the lifting front attached to the gantry chassis direction is suspended and a support frame for loading shaped stones on trucks has, on which a gantry track that can be moved on high rails by means of articulated gears movable pair of clamping plates stored io pallet truck known with a simultaneous Aufist, characterized in that the take of usually several layers from several ne-supporting frames from two rows of shaped stones lying next to one another on guide rails (16) on the sides of the portal chassis (2) serving vertically above the gripper that is guided on the portal, A lifting device attached via a central support (14) with a chassis by means of a rope connected box girders (12, 13) consists, 15 len is suspended pendulum. The gripper is a on which the s'ch over the length of the portal chassis rectangular beam frame, one of which is a crossbeam stells (2) extending clamping plates (10, 11) by means of Hy attached parallel to the longitudinal beam are articulated (37), and which each have a hydraulic cylinder for clamping together the from Steering gear (34, 35, 36) included, the joint-bar frame enclosed molded stone layer sam can be pulled ao with the other over a longitudinal traverse (32). The lowest layer then forms a kind of Sta from a single, centrally arranged vertical plate for the upper layers, len hydraulic cylinder (30) is driven.

Straddle carrier with gripper after finding a straddle carrier with a dem Claim 1 or 2, characterized in that simultaneous recording of at least one layer each clamping plate (10, 11) in the articulation point (37) several adjacent rows of formals Hollow shaft is formed; the grapple that is used over the stones from above, the one on the entire clamping plate length extends. 35 lifting device attached to the portal chassis is suspended and has a support frame, on which a jointed gear moves in opposite directions Bares clamping plate pair is stored. The invention has for its object to be a 40 straddle carriers of the aforementioned type The invention relates to a straddle carrier with form that the base of the straddle carrier a simultaneous recording at least as space-saving as possible for recording a possible a layer of several juxtaposed lends a large area of juxtaposed Rows of shaped bricks from above serving grippers. the rows of stones is used that the gripper to In the case of a continuously circulating shape on rails, 45 rapid and safe work even with the lifting movement. machine, the stone stones lying on the ground are positioned in relation to the portal chassis first covered in curing chambers and then recorded from the fact that the sensitive joint this is protected from contamination by a traversing gear on the same rails. ble straddle carrier by means of the recording is chert and that for quick work at low each a layer of in a row next to each other- 50 expenditure on manufacturing costs a simple, ma- lying shaped stones from above serving gripper fast gripper drive is provided, the one and a laterally extendable, operationally safe, even distribution of the clamping Gripper boom with rigid gripper lift guide in addition to forces over the entire area of the large-scale piled up the web to then ensured by fork gripper. Forklifts transported away with stone clamping fork and to 55. According to the invention, this is achieved by to be assembled in larger stacks. that the support frame consists of two guide rails When making the floor on simple, smooth floors, vertically guided surfaces on the sides of the gantry chassis, z. B. in halls, the entire halls are connected to one another via a central beam The floor area is used to create the largest possible box girder, which extends over the Number of shaped bricks for a short time, e.g. B. a day long, 60 length of the portal chassis extending clamp vorzutrocknen. Then the shaped bricks are hinged to panels, and each of which has a joint square to create for the next production, transmission included, which together with the other, clears and until it is completely set in the open air via a longitudinal traverse from a single, central one stacked. For this purpose, either forklifts arranged vertical hydraulic cylinders have been driven up to now simple forks and pallets (stacking plates) 65. or special stacking devices with swiveling up and down The invention consists in the useful combinable Cantilever hanging grippers for two formation of the aforementioned features, individual of which rows of stones used. While the latter are only known about in themselves. So it is known that the gripper
