3. Assembly of the kit
In case of the kit BR13x-3, the sub-structure and the floor are component
part of the kit and must be assembled professionally.
3.1 Assembling of the longitudinal supports (sub-structure)
•
Place both longitudinal supports with the vehicle-specific, pre-as-
sembled brackets on the vehicle chassis. The V-Shaped section must
point in the driver cab direction (Fig. 311) and the upper leg sup-
ports to outside.
•
Align the longitudinal supports according to the
diagonal dimen-
sion y
and
hole separation dimension x
. Consider absolutely the
measurement dependencies x1 = x2, as well as y1 = y2 (Fig. 312). The
difference between the diagonals must not exceed 4 mm!
The supports should rest on the longitudinal stringers flush with the
outer edge of the vehicle frame (Fig. 313) and keep the same sepa-
ration distance to the driver cab in front in each case.
Attention:
In case of iso-floor, the hole separation dimension x
listed in the type sheet is to be adhered to absolutely !
Observe the construction and modification instructions of the re-
spective chassis manufacturer, in particular the positioning and the
type of connection of the substructure, flexible or rigid. At a mini-
mum, the two front fastenings must be spring-supported. Otherwise
forces occurring during driving (e.g. with cornering, load changes
or uneven loading) are transferred to the structure. This can lead
to cracks in the sub-structure and in the set-up structure. Possible
adaptation work, such as e.g. bores, are the responsibility of the ve-
hicle constructor.
•
Now measure again and check the hole separation dimension x and
the diagonal dimension y. If required , re-adjust. If the dimensions
are consistent, first screw the front and rear brackets securely and
after that the remaining brackets follow.
3.2 Assembling connection of floor and front wall
•
Now place the floor onto the longitudinal supports (Fig. 321) by
means of a crane and suitable belts with double-stud fittings. (Fig.
321).
Latch the fittings into the integrated airline rail in the cen-
tre of gravity of the floor.
As an alternative, you can possibly use a
forklift with sufficiently long prongs.
•
A foam strip protects the side floor profile and the subordinate seal-
ing cord. Now pull these strips carefully out in order not to damage
the seal.
•
Align the floor centrally to the longitudinal chassis beams and the
driver cab. There must be a separation distance of approx. 1.20 m to
the front wall, so that you can attach the front wall later (Fig. 322).
Danger:
Toppling module assemblies endanger life and
limb.
Secure the floor against tilting and falling,
where you fix it with four screws at the longitudi-
nal supports.
•
If the kit is equipped with side marking lights, a cable runs in front
crossways within the floor. Ensure that the plug connectors hang
down freely on the side (Fig. 323).
