Assembling counterweight combination

Danger of overturning when slewing with a rigged counterweight!
When a counterweight version is rigged, check whether slewing is permit-
ted with the current rigging mode (outrigger span, working radius). Correct
the rigging mode if necessary;
p. 12 - 83.
Risk of crushing when setting down the counterweight sections!
Make sure the helpers keep a sufficient distance away from the counter-
weight sections with any parts of their body when setting down the coun-
terweight sections.
Remove all objects from the counterweight platform that could become
jammed or crushed!
Risk of crushing when slewing the superstructure!
Anyone who climbs onto the carrier using one of the access ladders is
within the slewing range of the superstructure.
Make sure nobody uses the access ladders (e.g. helpers) while you lift
a section onto the carrier.
Risk of accidents due to falling counterweight sections!
Only attach the counterweight sections to the appropriate slinging points
and use lifting gear of sufficient load bearing capacity.
The counterweight sections should be lifted only one at a time. The slinging
points are not designed for hoisting stacked counterweight sections.

Slewing with rigged counterweight ,
Set down 7 t (15,432 lbs) base plate
Retainers (1) and (2) are fitted to the
counterweight platform, which are used to
bring the 7 t base plate into the correct
position for rigging.
•
Position the 7 t base plate in such a way that
the retainers (2) grip into cutouts (3).
For larger counterweight combinations, now
set additional counterweight sections onto
the 7 t base plate.
