3-
On the corner end of the motorized unit where the bearing bridge will be overlapped,
attach a 6' (1,8 m) bridge to the motorized unit to provide support for the bearing
bridge structure (see “C” in fi g. 3.48 and fi g. 3.49). Refer to the installation instructions
for a cantilever bridge on p. 44 of this section.

4- Install a cantilever bridge (see “D” in fi g. 3.48 and fi g. 3.49) on the “corner” motorized unit
on the side opposite to where the bearing bridge structure will be installed.

5-
Carefully lower the bearing bridge structure on the corner motorized unit and on the
6' (1,8 m) bridge installed on the other unit (“C” in fi g. 3.48 and fi g. 3.49, making sure
the overlap is appropriate at both ends. The edge of the bearing bridge must be in
line with the edge of the 6' (1,8 m bridge on the “corner” unit, creating a 12" (30,5 cm)
overlap on the corner of unit (see fi g. 3.47, p. 54).
6- Make sure all safety chains are properly installed and secured.
7- Once the bearing bridge structure and the cantilever bridges are installed, apply the
appropriate counterweight on the unit supporting the angled bearing bridge structure.
The counterweight must be set between the mast section and the edge of the
motorized unit (see “CW” in fi g. 3.48 and fi g. 3.49). Refer to p. 89 and p. 90 of the Load
Capacities section for counterweight requirements and load capacities for an inside
or outside corner bearing bridge confi guration.
8- Proceed with the installation steps as described in the method of installation
appropriate for the confi guration. For more information about methods of installation,
refer to p. 18 of the Motorized Unit section.
