Undoing the connection
• Check whether section 1 is pinned to the main boom head at the front
right with both pins (1);
à p. 3 - 49.
• Secure the lattice extension with a guide rope; à p. 3 - 27.
– With derricking swing-away lattice
• Raise the lattice extension completely; à p. 3 - 75.
• Check whether the holder (2) has been completely raised out of the
slewing axis (1). If this is the case, the connection is undone.
If the slewing axis remains partially inside the holder, you must retract the
slewing axis, as when rigging an inclinable lattice extension.
– With inclinable swing-away lattice
With the inclinable lattice extension, you must retract the slewing axis as
follows.

Risk of accidents due to falling swing-away lattice
Before undoing the connection, make sure section 1 is pinned to the front
right of the main boom head.
This will prevent the swing-away lattice from falling down and injuring you
or other persons when undoing the connection.
G
Risk of accidents due to the swing-away lattice swinging of its own accord
Secure the lattice extension always with a guide rope on the main boom
before retracting the slewing axis.
This will prevent the lattice extension from slipping off the run-up rail of its
own accord, swinging around and knocking you off the carrier or injuring
other persons in the slewing range.
