12.2.2 Safe distance from slopes and pits
Erect the crane at a safe distance from slopes and pits. The distance also
depends on the type of ground if the slopes and pits are not supported.
Rule of thumb:
If you are working on
non-cohesive or filled-in
ground, the safety distance (a) must be twice
as large as the pit depth (b).
a = 2 x b
If you are working on
cohesive or undisturbed
ground, the safe distance (a) be as great as the
depth of the pit (b).
a = 1 x b
The safe distance is measured from the base
of the pit (c).
In addition to this the safe distance (d)
between the outrigger pads or support mate-
rial and the pit border must always be more
than 2.00 m (6.6 ft).
