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.
Setup and Confi gurations
Multiple units installation with mast ties – pre-installation
(requires two twin mast adapters – sold separately)
Positioning the second motorized unit (cont’d)
9-
Align the motorized unit with the end of the bearing bridge structure lower it into position,
making sure the base is properly aligned with the face of the work.
10-
Using the jacks on the lateral base extensions, level the mast on both its front and
side axis, then, if required, use metal shims to make sure that the base sits squarely
and level on the cribbing.
Installation of the fi rst cantilevers
Completing the installation of the bearing bridge
11-
Bolt the twin mast adapter at the end of the bearing bridge structure to the main frame
of the second motorized unit. It is important to make sure that the locking plates on the
twin mast adapter remain in place until the installation of the bearing bridge structure
is complete.
12-
Complete the installation of the bearing bridge structure as described in steps 3 through
6 of the installation instructions on p. 53 of the
Bridges
section.
Verifi cation of limit switches and screen alerts (on each motorized unit)
14-
If the units used in the setup are electrical units, select the appropriate power cables
for the height of the masts. Refer to the
Power Cable Selection Chart
on p. 72 of the
Power Pack and Operating Components
section for help with the selection of the power
cables. Make sure that the overall length of each cable is suffi cient for the installation
(height of setup, distance from power source, acceptable overall slack in cable).
15-
Install and connect the power cables.
This installation must be performed by a
certifi ed electrician
. For instructions on the installation of a power cable, refer to
the startup preparation instructions on p. 71 of the
Power Pack and Operating
Components
section.
WARNING
It is important to verify limit switches and screen alerts on both motorized units
as
simultaneously as possible
.
Connection of the units and control panels to the power supply (electrical unit)
13-
Using any appropriate lifting device such as a crane or a rough terrain forklift,
install
only one 5' (1,5 m) bridge
at the cantilever end of each motorized unit.
