4 - CALCULATION OF THE MAXIMUM FORCE ALLOWED ON THE
STABILIZER
1)
Column axle offset from the middle
of the vehicle to the left or to the
right (cm)
2)
Longitudinal distance from column
centre to the middle of the
additional stabilizer, or to the
middle of the closest stabilizer
cylinder in case of stabilizer with
side-by-side rods (cm)
3)
Maximum dynamic moment of the
crane stated by its manufacturer
(daNm).
Filing up the two equations in pict. 7
with the above data, the maximum
force allowed on the cylinder is drawn.
Compare such data with the attached
table of maximum allowed force rates,
and check that it is lower, i.e.:
R max < R allowed
If not so, repeat the calculation after
increasing the stabilizer distance from
the crane (if possible), or choose a
stabilizer with a bigger spread, or opt
for the stabilizer with the immediately
higher capacity.
