3.4.20 Setting the angle – without auxiliary crane
If an auxiliary crane is not available, the swing-away lattice must be set
down before it is angled.
Entering the SLI
code
To set an angle without an auxiliary crane, you must enter an SLI rigging
code. The SLI rigging code depends on:
– The rigged outrigger span
– The rigged counterweight
– The working position
• Enter the SLI rigging code for the angle for the current rigging mode of
the truck crane;
à Lifting capacity tables – Chapter Rigging tables – Swing-
away lattice extension
.
• Slew the superstructure into a working position permitted by the Lifting
capacity table
for the SLI rigging code set.

Risk of damage to the hoist rope
Unreeve the hook block and set down the hoist rope beside the swing-away
lattice before you angle the swing-away lattice.
This will prevent the hoist rope from being damaged when the swing-away
lattice is set down on the ground in order for it to be angled.
G
Risk of overturning in impermissible rigging mode
Always enter the SLI rigging code for the current rigging mode of the truck
crane, and only slew the superstructure into the working position permitted
by the SLI rigging code set according to the
Lifting capacity table.
This will prevent the truck crane from overturning when the main boom is
extended.
G
Risk of overturning with the hook block (hook tackle) raised
The telescoping range enabled with the set rigging code is only permissible
for telescoping without a load and hook block / hook tackle.
If the main boom is fully extended, load measurements are not possible
and the SLI monitoring is based on the working radius.
For this reason, you must always unreeve the hook block. This will prevent
the truck crane from overturning when the main boom is extended.
