(requires two twin mast adapters – sold separately)
WARNING
It is recommended that two persons handle all rise and descent operations of
each motorized unit and that at least
one
of those two persons is a
qualifi ed
operator
. It is important to coordinate the motion of motorized units linked by a
bearing bridge to keep the structure as level as possible.

It is important to make sure to plug in all inclinometers and to enable the
inclinometer option on each display screen of the bearing bridge installation. It is
also essential to perform the 0-degree level adjustment for each inclinometer.

With the unit at base level, install as many additional cantilevers as is required and
allowed. Refer to the
Load Capacities
section on p. 94 for the maximum number of
bridges allowed in a setup.
5-
Install additional equipment and accessories as is required and allowed. For more
information about the combined use of equipment and accessories in an installation,
refer to the tables for the combinations allowed or restricted in linked and unlinked
