Single unit installation with mast ties – pre-installation
B
The following installation steps can be used for
standard
and
non-standard
confi gurations of single unit tied installations
. For more information about the
defi nition of a standard confi guration, refer to p. 20 of this section. 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
confi gurations on p. 17 and p. 18 of this section.
1-
Prepare the motorized unit and the area where the setup will be installed as described
in the general guidelines starting on p. 17.
2-
Lift and align the base of the motorized unit with the face of the work and lower it into position.
3-
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.
Positioning the motorized unit
Connection of the unit and control panel to the power supply (electrical unit)
4-
If the unit used in the setup is an electrical unit, select a power cable appropriate for the
height of the mast. 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
cable. Make sure that the overall length of the cable is suffi cient for the installation
(height of mast, distance from power source, acceptable overall slack in cable).
5-
Install and connect the power cable.
This installation must be performed by a certifi ed
electrician
. For instructions on the installation of the power cable, refer to the startup
preparation instructions on p. 71 of the
Power Pack and Operating Components
section.

Using any appropriate lifting device such as a crane or a rough terrain forklift,
install
only one 5' (1,5 m) bridge on each side of the mast
. Refer to the
Bridges
section
on p. 50 for instructions on bridge installation.
Pre-installation must be performed in a linked configuration only. Once
pre-installation is complete, refer to p. 34 of this section for instructions on how
to split a motorized unit, if required and allowed.
For safety reasons, it is mandatory to make sure that the operation of the top limit
switch is verifi ed and to make sure that the mast guards and mast head are put
back into place every time mast sections are added to the installation. Grease
must be applied to the racks of the newly added length of mast section.
A
Adding mast sections and tie levels progressively
22-
Whenever it is necessary to add mast sections and/or tie levels, remove the mast
guards and the mast head. Install as many mast sections and tie levels as is required
and allowed.
23-
Put the mast head back into place. Make sure the top trigger plate is positioned properly
and in good condition.
24-
Apply grease to the racks of any
newly added mast section
,
from the top of the
new length of mast down
. Newly applied grease must be allowed to stand for 2-3
hours before the motorized unit can travel up the mast again. Refer to p. 133 of the
Transport, Storage and Maintenance
section for more information on the appropriate
lubrication method.
25-
Put the mast guards back in place.
26-
Perform a verifi cation of the setup as described in steps 20 and 21.
