• If necessary, relieve the pin (1) by raising
slightly.
• Move the pin (1) into the position for the
required angle of inclination, e.g. 40°;
à Setting the angle – with an auxiliary crane,
p. 3 - 79.
• Raise the main boom slowly.
In doing so, the head of the swing-away lat-
tice is pulled across the ground.
• Lower the main boom until the swing-away
lattice head no longer touches the ground.
The swing-away lattice is inclined to the set
angle of inclination in the process, e.g. to 40°.
If you have inclined the truck crane with the outriggers in order to set the
angle of inclination, then level the truck crane again now.

A crane example is illustrated in each of the following diagrams.
• Fully retract the main boom without touch-
ing the ground with the swing-away lattice
(raise the boom now and again if neces-
sary).
• Set the head of the swing-away lattice down
onto the ground.
