Abstract: A hydraulically actuated locking element with two locking bolts axially displaceable on an axis. A carrying structure is provided with two, slidingly guided hydraulic cylinders, two cylinder bottoms, which act as locking bolts and are designed as force-transmitting cylinder bottom. A centrally fastened, common piston rod of the hydraulic cylinders is provided with a stationary piston at each piston rod end. A centrally rigidly connected piston rod fastening is arranged in the carrying structure and between the two, sliding hydraulic cylinders. The piston rod fastening and the piston rod are provided with holes for guiding hydraulic oil.

Abstract: A bridge-laying device is placed, together with bridges or bridge sections (26), on an armored tracked vehicle (7) used by the armed forces in various countries, after removal of the armored turret. The laying device is constructed as a unit on a guide support (10) and placed on the annular part (25) of the turret of the vehicle (7), to which it is screwed. The laying device includes laying support (10) hydraulically mobile in the longitudinal direction, a mobile front laying arm (8) and a swivelling rear jib (16). Articulated supporting legs (12) which support the vehicle during the laying operation are also provided. These supporting legs are raised when the bridge-laying vehicle (7) moves.

Abstract: A device for adjusting adjacent differently immersed amphibious vehicle or floating bodies to a common coupling level, in which the oppositely located end or side walls of the vehicle or floating bodies to be interconnected are provided with supporting arms and abutment surfaces while the supporting arms arranged on the respective higher located vehicle or floating body are pivoted below abutment surfaces of the respective lower located vehicle or floating body which in response to a further movement of the pivotable supporting arms are automatically lifted into the common coupling level.

Abstract: A vehicle, especially a wheeled vehicle, for transporting and placing bridge parts of a portable bridge. The vehicle has a frame, on the forward end of which is mounted a cab. Behind the cab is mounted a support unit for use in placing the bridge parts. The support unit is pivotal about vertical axes and, during the placement process, is spaced from and in front of the cab and is located, in part, on the ground.
