12.9.10 Setting down counterweight for driving
Which parts of the counterweight sections can be transported on the turn-
table and counterweight platform when driving the truck crane depends on
the driving mode of the truck crane;
à Driving modes, p. 6 - 1.

mounted on the turntable.

– The 2.9 t plate (1) and a 2.3 t plate (2) are
mounted on the turntable,
– the 1.1 t base plate (3) is on the counter-
weight platform
For driving with axle loads greater than 12 t
The 2.9 t plate (1) and two 2.3 t plates (2) are

Risk of damage to the derricking cylinder
Set down only the 4.6 t plate on the 1.15 t plate.
In this way you can prevent the derricking cylinder being pushed against an
incorrectly assembled counterweight combination and becoming damaged
when the main boom is being set down.
