6.3.1 MAST/POLE INSTALLATION
6.3.1.1 MAST/POLE SELECTION
The types of section of the mast/pole where the MBS Unit can be mounted are the followings:
Circular section: Diameter from 1.18 in to 5.12 in.
Square section: From 1.18 in x 1.18 in to 3.35 in x 3.35 in.
L section: From 1.18 in x 1.18 in to 4.33 in x 4.33 in.
In the choice of the mast/pole where the MBS Unit is being installed the following recommendations
must be followed:
The mast/pole has to support the loads due to the installation of some elements on
them.
The mast/pole has to support the loads due to the action of the wind, snow as well as its
own weight, because these are going to induce its flexion.
o The mast/pole must have the enough inertia both lateral and frontal in order that the actions
of different loads do not induce permanent deformations on it.
The manufacturer of the mast/pole must evaluate the structural factor of the mast/pole
correctly depending on its type.
It is necessary to take into account both the height where the MBS Unit is installed and
its weight/dimensions (See section “MBS Unit” in chapter (F067326PT) “SBS Technical
Description” in the Standard Technical Manual).
It is recommended to choose a lattice mast/pole in case of this one has a high height
and it is going to be submitted to important flexion efforts. In any case, it is
responsibility of the manufacturer of the mast/pole to determine if the resistant
section of mast/pole is suitable.
The brackets should be installed tight enough to support the MBS Unit without causing deformation
of the mast/pole or areas of corrosion.
