Brückenpanzer 68

The Brückenpanzer 68 (Bridge Tank 68) is an armoured vehicle-launched bridge manufactured by the Eidgenoessische Konstruktionswerkstaette, which was used by the Swiss Army. It is the bridge-laying version of the Panzer 68 tank.

History
A prototype was built built by modifying a Panzer 61 and was announced in 1967. In 1972 the Federal Council approved production of a version based on the Panzer 68. The Panzer 68 hull was unchanged, with the gun turret replaced by the bridge-laying mechanism. A total of 30 vehicles were manufactured between 1974 and 1977 and were assigned Swiss Military identification numbers (M codes) M77882 - M77911.

In 2005, 16 vehicles were taken out of service, the remaining vehicles were placed out of service in 2011. In 2012 a Brückenpanzer 68 was given at the Military Historical Foundation of the Canton Zug in Neuheim Neuheim ZG.

Specifications
The bridge consists of two track carriers of aluminum alloy. Each track support consists of two end portions and two intermediate portions. It is not a scissors bridge, it is transported in its entire length. The storage beam is mounted between the two tracking beams, which is connected to a hydraulic ram. The laying of the bridge is carried out by the hydraulically operated bar with which the whole bridge is moved over the guide frame (support bar). For laying, the storage beam is first extended and placed with the tip on the ground (thus, no support shield is necessary). Then the bridge is moved along the storage beam. After laying down the bridge, the storage beam is detached and is retracted.
