à p. 6 - 36.
– The boom pivot pin is pulled out;
à p. 6 - 33.

Lifting from the
turntable
• Align the auxiliary crane in such a way that the main boom can be raised
vertically without swinging.
• Lift the main boom forwards and upwards
from the turntable. Make sure that:
– The connection lines (2) do not hang
loose,
– The pivot point (1) is higher than the
driver's cab.
S
Risk of damage to driver's cab!
Lift the main boom far enough to ensure that the pivot point of the derrick-
ing cylinder does not damage the driver's cab.
G
Danger of hands and arms being crushed!
Whilst rigging the crane, maintain sufficient distance from the main boom
and do not reach in between the connecting points. This will prevent you
from being crushed between the turntable and the main boom.
