Suitable approaches to the auxiliary romps are:
-
level crossings,
-
dead and tracks with paved approaches and areas,
-
flange groove tracks in the area of paved roads,
-
crushed stones piled in the tracks, covered with auxiliary road cover (hexagon slabs) (Appendix 1).
3. In accordance with Appendix 1 the fixed bridge, short is to be mounted on both sides of the ramp (from the fishplate-
thrust anchorage) by means of two tiedown chains (of the heaviest vehicle) with shackles, size 4, and is to be secured at
the external slinging eyes or the screw coupling, of the rail wagon to avoid falling off. The tiedown chains are to be
tightened only loosely in order to enable motion compensation between bridge and rail wagon when vehicles pass over
the bridge. That is why the floor is not secured in position; it must, however, be plain in order to ensure a safe
distribution of the load. Wooden railway sleepers or solid square timbers not smaller then 18x18x400 cm are to be
placed underneath as footboards and for the distribution of the load at the point at which the bridge rests on the wagon.
The fixed bridge, short can be constructed manually in solid construction, without any mechanical lifting devices, by one
team within one hour.
4. In accordance with Appendix 2 the procedure for theM 48 armoured-vehicle-launched bridge is the same as the Biber
armoured-vehicle-launched bridge.
M 48 armoured-vehicle-launched bridge is tied to the rail wagon by means or two tiedown chains (of the heaviest
vehicle).
-
from the slinging eyes on both sides, outside or inside, to the screw coupling of the rail wagon or
as cords around the front plate of the bridge to the screw coupling of the rail wagon.
5. In accordance with Appendix 3 the Biber armoured-vehicle-launched bridge is to be placed on the wagon in such a
manner that the bearing surface is protected by a timber not smaller than 20x20x400 cm, placed underneath; in the case
or wheeled vehicles, however, the timber must not be smaller that 18x18x400 cm. At the bottom the end of the bridge
must rest in its entire width on a plain surface.
The armoured-vehicle-launched bridge (Biber) is fastened to the rail wagon by means of two tiedown chains (of the
heaviest vehicle) from the second shackle mounting on the inside to the screw coupling of the rail wagon.
