3 - CHOOSING THE STABILIZER
T
he
MAXISTAB
range of stabilizers is additional for cranes which already have their own stabilizers,
when the stability of the vehicle is not sufficient.
In case the vehicle on which a crane is installed is smaller than the minimum vehicle foreseen by the
manufacturer for that kind of crane, it will be necessary to install an additional stabilizer.
The choice of the additional stabilizer is to be made according to two main factors:
1)
The stability checking of the vehicle with crane at full load and in the most unfavourable conditions
2)
The maximum force which has to be borne by the additional stabilizer.
Each crane manufacturer gives some
indications, which you can refer to, for
the stability calculation of the vehicle
with crane installed.
In case of use or installation as main
stabilizer near to cranes, aerial
platforms or for other employments, in
order to guarantee the stability of the
vehicle, the installer has to calculate
the stability of the system and the
actual stress the stabilizer will be
subjected to, by following the
calculation systems imposed by the
regulations in force, and making sure
that the max. stress borne by the
stabilizer is lower than the rates
indicated in the table at page 7.
Anyway, in the
MAXISTAB
range you
can choose among the following
stabilizer models:
-
fixed (
F
)
-
extendable with opposite rods
(
EMO/EHO
)
-
extendable with side-by-side rods
(
EMA/EHA/ELHA
)
-
extendable with two telescopic extensions each side (
EXHA/EXPHA
)
(see Pict. 6).
As far as the choice of stabilizer size or type according to crane lifting moment is concerned, it is
important to remember that the moment rates mentioned in the range brochure are only an indication,
as they cannot consider the real distance of the stabilizer from the crane, or the actual dynamic moment
of the crane itself.
Therefore, in order to make a correct choice, please follow the calculation system shown at page 6.
