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).
If you are working on cohesive or undisturbed
ground, the safe distance (a) be as great as the
depth of the pit (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).
