Relieving the con-
necting points
Proceed in the following manner to relieve the strain on the connecting
points:
(A) – With derricking swing-away lattice
• Lower the swing-away lattice until it is with
the skids (2) on the ground (if necessary,
override the lifting limit switch).
• Continue the lowering procedure carefully
until the connecting points (1) are in line or
the pins have been relieved;

(B) – With inclinable swing-away lattice
• Sling the swing-away lattice with an auxiliary
crane.
• Carefully raise the swing-away lattice until
the connecting points (1) are in line or the
pins have been relieved.
Hydraulic rigging
aid (additional
equipment)
The hydraulic cylinder is operated with the
hand pump (1) to pull a swing-away lattice
toward the main boom during rigging and
unrigging.
When rigging:
– Align the bores in the connecting point (3);
the pin can be inserted.
When unrigging:
– The pin on the connecting point (3) is
relieved.
G
Falling hazard if ladder is set up incorrectly
Do not lean the ladder in the area of the swing-away lattice. You will fall
when the swing-away lattice is swivelled. Lean the ladder only in the area
of the main boom.
