Setting an angle of
20° or 40°
This section is based on the assumption that the swing-away lattice has
been pinned in front of the main boom and the unreeved hoist rope has
been set down beside the swing-away lattice.
• Enter the SLI rigging code for the inclination;
à p. 3 - 80.
• Extend the main boom as far as permitted
with the set SLI rigging code, or as far as
possible given the space available.
• Lower the main boom until the swing-away
lattice head touches the ground.
• You can incline the truck crane further if the
ground is unable to be reached;
à p. 3 - 85.

During the following steps, the swing-away lattice head is pulled or pushed
over the ground. Lay boards, for example, under the skids so that the head
is not pushed into the ground or damaged.

G
Risk of accidents in the event of other procedures
For the procedure described here, the swing-away lattice is set down on the
ground. If the swing-away lattice is to be set down on packing for inclina-
tion, please bear in mind that the swing-away lattice will slide towards the
truck crane when raised, until the angle of inclination is reached.
The swing-away lattice could slip off inappropriate packing material, fold
down and cause injuries.
G
Risk of accidents when overriding the SLI
Never override the SLI if the crane movements are switched off. This will
prevent you from slewing beyond the permissible range and the truck
crane overturning.
