Value of the maximum reaction F on the two feedback at the limit of stability
Cr = total weight force (daN)
P = total weight of the crane strength (daN)
W = wind force (daN)
I = horizontal inertia forces (daN)
F = maximum force applied on the two feedback at the limit of stability (daN)
a = distance from the axis of tipping crane center of gravity (m)
b = distance from the axis of tipping load (m)
c = distance from the axis of tilting force of the wind (m)
d = the center of gravity of the horizontal forces of inertia (m)
= center distance and strength of cranes inertia axis tilt (m)
f = distance from the axis of tipping load mass center of gravity (m)
Ms (bar) = P * a = stabilizing moment cranes
Mr (bar) = W * b * c + Cr = overturning moment cranes
d = (P * and f * + Cr) / (P + Cr)
F (daN) = (Ms - Mr) / d
NB. Each buffer must not have a maximum reaction greater than F / 2
