Setup and Confi gurations
Installation of units and bridges
Multiple units installation with mast ties – pre-installation
(requires two twin mast adapters – sold separately)
Positioning the fi rst motorized unit
1-
Prepare the fi rst 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.
Installation of the bearing bridge structure
4-
Make sure the bearing bridge structure has been assembled as described in the
assembly instructions on p. 52 of the
Bridges
.
5-
Make sure that a twin mast adapter is installed at the end of the bearing bridge structure
to be attached to the fi rst motorized unit. For instructions on the installation of a twin
mast adapter, refer to p. 52 of the
Bridges
section. 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.
6-
Using a rough terrain forklift, a crane or any other appropriate lifting device, lift the
bearing structure, align it with the motorized unit installed and lower it into position.
7-
Still holding the bearing bridge structure, bolt the twin mast adapter to the main frame
of the fi rst motorized unit. Make sure that the end of the bearing bridge that is not yet
bolted to a unit is
supported
.
Positioning the second motorized unit
8-
Prepare the second motorized unit and the area where the setup will be installed as
described in the general guidelines on p. 17.
