Question #778
The safe crane setup distance from the excavation edge depends on:
Bezpieczna odległość rozstawienia żurawia od krawędzi wykopu zależy od:
a
the angle of the crane boom
kąta nachylenia wysięgnika żurawia
b
wind strength
siły wiatru
c
weather conditions
warunków atmosferycznych
d
the depth of the excavation
głębokości wykopu
Correct answer
Why?
Excavation depth (głębokość wykopu) affects the extent of the ground that could collapse under the outrigger load. Ground type and condition must also be assessed during setup. Weather can reduce ground bearing capacity, but weather conditions alone do not determine the required setback.
