2.4.3 Corner bearing loads
The corner bearing load is stated on each support leg. This value
must always be legible.
The load supported by each support leg is conically diffused in the
ground at an angle of 45 °. Safe clearance to the pits and slopes must
be maintained, and such clearance must be determined in accord‐
ance with the nature of the ground. The safe clearance is measured
from the foot of the pit.
On undisturbed, compacted ground, the safe clearance corresponds
to the pit depth, but must be at least 2 m.
On loose or backfilled ground, the safe clearance corresponds to dou‐
ble the pit depth, but must be at least 2 m.
2.4.4 Supports
The placing boom must not be raised until the machine has been sup‐
ported in accordance with the Operating Instructions. There is other‐
wise a risk of the machine toppling over.
Swing out and telescope the support legs to their end positions in se‐
quence. Intermediate positions are prohibited to guarantee stability.
Exceptions are machines which have been equipped by the manufac‐
turer with a device which allows secure erection with a reduction in
support. Check the corresponding notes in this regard in the operat‐
ing instructions.
