摘要:
An arrangement for laying a bridge, in which a vehicle carries a plurality of track support sections of a bridge to be laid. The vehicle has a laying device which includes a laying support with cantilevering rails traveling on rollers. Telescoping stays are located at ends of the laying support, and a left-side track-laying device and a right-side track-laying device are mounted on telescoping shafts. The telescoping shafts are displaced hydraulically across the longitudinal axis of the vehicle. Each of the track-laying device on the laying support has provision for placing the track support sections. A piston-and-cylinder is located on arms mounted at ends of a horizontal one of the shafts, whereas piston-and-cylinder is mounted on ends of a rear one of the shafts.

A support device of a laying vehicle such as a track laying vehicle includes a vehicle pan providing a support surface, the support surface having a central plane, a support shield for engaging the ground, a first guide element hingedly connected between the support shield and the vehicle pan, a first bearing connecting the first guide element to the support shield, a second guide element hingedly connected between the support shield and the vehicle pan, a second bearing connecting the second guide element to the support shield, a first piston-and-cylinder unit connected between the support shield and the vehicle pan, a first piston-and-cylinder unit bearing connecting the first piston-and-cylinder unit to the support shield, a second piston-and-cylinder unit connected between the support shield and the vehicle pan, a second piston-and-cylinder unit bearing connecting the second piston-and-cylinder unit to the support shield, the first bearing, the second bearing, the first piston-and-cylinder unit bearing and the second piston-and-cylinder unit bearing having a common support shield bearing axis. A side force transmission arrangement is provided for transmitting side forces from the support shield to the vehicle pan. The side force transmission arrangement preferably includes at least one spherical hinge connection arranged on the support shield centrally with respect to the vehicle central plane and an additional guide element with a side force transmission member. The additional guide element is connected to the spherical hinge connection, the spherical hinge connection being located in the support shield bearing axis.
摘要:
The invention concerns a bridging system comprising several uniform bridge section in the form of track supports (1). The width of the bridge can be continuously adjusted with telescoping pipes ( 2 ). The stationary ramps ( 3 ) on the track support are slotted like a comb and, once the have been assembled and connected to the pivoted-out lower truss system (4), can accommodate any compression forces and bending moments that occur when traveled. Since each track support is the same shape, the bridging system has a smoothly curving upper roadway edge.The traction component (5) in each track support travels back and forth between pivoting stays (9) provided with connectors (8) and the overall lower truss system can be pivoted into the track support.This bridging system, which consists of modular track supports (1), is outstanding for its compact traveling state and few connectors and can be positioned by appropriate transporting and laying equipment.
摘要:
An armored bridge-laying vehicle with a laying device for bridges or bridge sections located one on top of another, wherein a single laying girder is rotatably mounted on a support ring structure on the tower ring. The laying girder is pivotable around a horizontal pivot bearing, and the pivoting is performed by a piston-and-cylinder unit. Telescopic U-shaped girders are arranged inside the laying girder, and the top edges are located in the same plane as the upper chord edges of the laying girder. The bridge elements are laid by a flanged feeding unit, support rollers and a pivotable arm in the rear of the laying girder.

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.
