Setting

If a hook block is reeved on the main boom during operation with the lattice
extension, the loads given in the Lifting capacity tables decrease and the SLI
subsequently switches off earlier.
The values which must be deducted from the load capacities depend on the
length of the lattice extension and the weight of the hook block. You will find
a table with the values in the lifting capacity tables in the section Information
on working with the swing-away lattice extension .
In the case of a hydraulically derricked lattice extension, the length of the lat-
tice extension or boom extension is also given and displayed.
•
Enter the current reeving at the SLI.
•
Enter the current rigging mode on the SLI, either using the corresponding
SLI code according to the lifting capacity table or using the individual com-
ponents.
•
Check whether the current rigging mode of the truck crane corresponds
to the displayed rigging mode.
Hoist display
The light which goes on must always be for the hoist with which the load is
to be lifted.
Light I : must go on if the load is to be raised with the main hoist.
Light II : must go on if the load is to be raised with the auxiliary
hoist.
If the telescopic sections are mechanically locked, the SLI will now release
•
Check:
1 The angle of the rigged lattice exten-
sion (inclinable)
2 The length of the rigged lattice exten-
sion
3 The number of reeved rope lines
4 The hoist which is switched on
5 The rigged counterweight
6 The rigged outrigger span
