Mechanical emer-
gency operation
The following requirements must be met before unlocking manually:
– The main boom must be lowered to the horizontal position so that the tel-
escopic section cannot retract by itself
or
– The telescopic section to be unlocked is secured against retracting by
itself by using an auxiliary crane. Telescoping is done with the auxiliary
crane
H
If the telescoping cylinder is positioned at a locking point, the correspond-
ing telescopic section cannot be locked or unlocked manually.
There are two M8 screws for every telescopic section:
– 200 mm length for telescopic section
I
– 150 mm length for telescopic section
II
– 110 mm length for telescopic sections
III
and
IV
Screw (

) into the locking pins (
1
) to unlock.
Pins located further inside are reached
through the holes (

).
You will need a suitable socket wrench (
2
),
with one shank being at least 200 mm long.

– To lock, the set screws are screwed out

Risk of accident due to sudden retraction of a telescopic section
Before unlocking the telescopic section, secure it against automatic retrac-
tion. This prevents the retracting telescopic section from severing one of
your limbs or the truck crane from being damaged or overturned by the
telescopic section suddenly retracting.
