calculated load-bearing area. If the surface of the outrigger pad is smaller,

If the outrigger pressure is 25 t and the ground has a load bearing capacity
of 40 t/m
2
. Then the required ground bearing area for this supporting cylinder
is 0.625 m
2
(= 6,250 cm
2
).
If the outrigger pad has a surface of 2,000 cm
2
, you would need to enlarge the
ground bearing area by packing the outrigger pads;
