Flush Bearing Bridge Adapter
(optional)
The optional fl ush bearing bridge adapter is used in a multiple units M2 Series installation to
bring the bearing bridge structure at an even level with the motorized unit(s) and achieve a
fl at deck platform. The fl ush bearing bridge adapter
cannot be used
to achieve an
offset,
angled
or
corner
(inside or outside) bearing bridge installation.
It is important to consider that the weight of the adapter (350 lb or 159 kg) must be deducted
from the load capacities of the motorized unit.
Installation of the fl ush bearing bridge adapter
1
-
Lift the top panel on the fl ush bearing bridge adapter. Align the adapter with the
motorized
unit.
2-
Bolt the top part of the of the adapter to the top of the fi rst motorized unit using four
1" x 2" long (
GR5
) bolt assemblies through the four
outer assembly sockets
in
the front and the back of the motorized unit.
Do not tighten the bolt and nut
assemblies
yet.
3-
Attach the bottom part of the adapter to the bottom of the motorized unit using bridge
link plates and pins sets (4) at the bearing bridge setting (fi g. 7.88 and fi g. 7.89).
4-
Tighten the bolt assemblies
(4) at the top of the adapter to 100 lb-ft (136 N-m).
Make sure to leave the top panel open
.
5-
Repeat steps 1 through 5 to install an adapter on the second motorized unit.

6-
Prepare
the
fi rst motorized unit and the area where the setup will be installed as
described in the general guidelines on p. 18 (steps 1 through 15). Make sure all
base outriggers are properly confi gured according to the installation.
Positioning the second motorized unit
7-
Determine the position of the second motorized unit. It is
essential
to make sure that
the
appropriate distance
between the two motorized units is
calculated precisely
by
measuring the length of the bearing bridge structure
without any allocations for
overlap
.
8-
Prepare the second motorized unit and the area where it will be installed as described
in the general guidelines on p. 18 (steps 1 through 15). Make sure all base outriggers
are properly confi gured according to the installation.
The following installation steps must be carried out as part of a selected method of
installation appropriate for the confi guration. For more information about setups and
confi gurations, refer to p. 18 of the Motorized Unit section.
WARNING
The fl ush bearing bridge adapter
cannot be used
to achieve an
offset
,
angled
or
corner
(inside or outside) bearing bridge installation.
9-
Assemble the bearing bridge structure as required and allowed. Refer to steps 1
through 6 of the installation instructions for a bearing bridge structure, on p. 46 of
the
