Installation should be carried out by qualified erectors/dismantlers under the
supervision of a competent person, in accordance with all applicable local regulations.
2-
In reference to the plan/layout drawing, make sure that all the components required
are available. Establish the position of the motorized unit, determine if there are
obstacles and what are the cribbing and mast tie requirements.
3-
Before installing the motorized unit, determine where the cribbing and the mudsills
will rest. The bearing surface under the motorized unit should be level, clear of debris
and have the proper bearing capacity (see the
Minimum Bearing Surface Capacities
table, fi g. 1.18, p. 15). Should the actual bearing capacity be inferior to the values in
the table, please seek instructions and recommendations from Hydro Mobile.
4-
On
freestanding installations
, the base outriggers on the
back
of the unit must be
extended completely to a total of 24" (61 cm) and locked in place with a lock pin
(second
hole).
The base outriggers on the
front
of the unit must be extended and locked in place to
the appropriate distance according to the number of planks required and allowed for
the installation, as shown in fi g. 1.25, p. 19.
With the front base outriggers completely extended, the
maximum width
of planking
allowed
in
front
of the unit on a freestanding installation is a
three-plank
wide
confi guration.
5-
On
tied installations
, the base outriggers must be closed completely. The
maximum
width
of planking allowed in
front
of the unit is an
eight-plank
wide confi guration and
requires the use of optional outriggers and accessories. Refer to p. 95 of the
Accessories
section for more information about outriggers and planking confi gurations.
For more information about planking and mast ties, refer to the
Mast Tie Schedule
table on p. 70 of the
Masts and Mast Ties
section.
6-
Distance from the fi nished wall (see “A” in fi g. 1.15, p. 13 and fi g. 1.16, p. 14)
should be the number of planks multiplied by the width of one plank, while allowing
6" to 8" (15 cm to 20 cm) of play. Add an additional 2" (5 cm) if using a toe board.
Refer to applicable local regulations to determine play or the maximum allowable
distance between the motorized unit, including its accessories, and the face of the work.
7-
Mark the position of mudsills while taking center-to-center distances into account.
Base level differences can be compensated by adjusting the height of the base
jacks or by building wood cribbing. Major differences in the level of the bearing surface
or obstacles can be bypassed using mast base plates. Refer to p. 115 of the
Accessories
section for instructions on the installation and use of mast base plates.
8-
Make sure that all loads have been removed from the platform and that all workers
have stepped down before lifting and transporting the motorized unit. Refer to p. 37
for more information on the lifting and moving of a motorized unit. Unload the motorized
unit with a rough terrain forklift or a crane. When moving the motorized unit with a
forklift, the unit must be lifted by the designated areas on the platform (see fi g. 1.6,
p.
9).
9-
Using a rough terrain forklift, a crane or an optional wheel set, position and align the
motorized unit with the face of the work or the structure. Before lowering the unit on
the bearing surface, lower the base jacks by 4" to 5" (11 cm to 13 cm). Refer
to p. 102 of the
Accessories
section for more information about lifting and moving
a motorized unit or a setup with a wheel set.
10-
Install a mast section on each of the bottom mast sections. Refer to p. 69 of the
Masts
and Mast Ties
section for instructions on how to install mast sections. Verify that each
mast is plumb on both its front and side axis. If required, level the motorized unit using
the adjustable jacks on the base. If mast sections remain out of plumb after adjusting
the base jacks, contact the Hydro Mobile technical support team.
11-
Remove the mast locking bar from both bottom mast sections. Store the mast locking
bars in their storage location. For instructions on the removal and storage of mast
locking bars, refer to p. 62 of the
Power Pack and Operating Components
section.
12-
Remove the transport hook from each cylinder. Retrieve and install the cylinder and
secondary hooks on each mast. Store the transport hooks in their storage location.
For instructions on the installation and use of hooks, refer to p. 62 of the
Power
Pack and Operating Components
section.
