Important instructions to be observed before commencing assembly and
disassembly
.
(
z Before the counterweight units are picked up or deposited, the vehicle must be supported by outriggers
and aligned in horizontal position, as specified.
z
Before commencing a slewing movement, make sure that the ballast cylinders are completely
retracted.
z
There must not be any persons or objects in the swing range - risk of accidents.
z
Before picking up the total counterweight, make sure that the individual counterweights are
correctly piled.
z
When picking up the counterweights from the chassis, make sure that the counterweight cylinders
are inserted in the grooves of the counterweights without touching them. The boom should be
raised to approx. 30°. If necessary, check visually.
z Before picking up, depositing the counterweights or slewing the superstructure, the operator must sound a
warning signal.
z
The counterweight units required for crane work must be identical with the load chart in question;
there is a risk of accidents otherwise.
z
When the basic boom is elevated and counterweights are mounted to the superstructure, the
outriggers must be fully extended; otherwise there is a risk of the superstructure tipping towards
the ballast side while it is being slewed.
z
Counterweights which are transported by an auxiliary vehicle must be located as close as possible
to the supported chassis, so that they can be picked up with the crane's bottom block. To this
effect, a second crane may be used.
z
The legal regulations regarding “ropes and hosting gear” in force in the country where the crane is
to be registered must be observed.
z
To pick up or deposit counterweight units which have been transported by auxiliary vehicles using the
crane's bottom block, the pertaining "set-up program = 0,0 t" must be programmed. The working radii
and boom lengths specified in it must not be exceeded. Risk of overturning, i.e. risk of accidents.
z Damaged counterweight units must not be used; they might
fall to the ground
and involve a
risk of
accidents
.
z
Counterweight units of other crane carriers must not be used.
z
When depositing partial counterweights on the chassis, the locking pin must be actuated.
z When the counterweight units are deposited, no ropes, wooden bars etc. must be located between them,
which would prejudice the safe support of the counterweights.
There is a risk of accidents due to sliding.
z
After crane work has been terminated, to prepare the crane for on-road travel, the counterweights must
be removed and transported by another vehicle, taking account of the legally admissible axle loads.
z For reasons regarding vehicle registration, the crane may only participate in public road traffic when its rig
arrangement has been changed accordingly.
