6.2 Assembly
The
hydraulic
system
of
the
machine
must
be
equipped
to
power
the
equipment.
If
the
machine
in
the
original
version
is
not
equipped
for
this
purpose,
it
is
necessary
to
modify
the
hydraulic
system
to
adapt
it
to
the
present
requirements.
This
modification
must
only
be
carried
out
by
authorised
personnel
from
the
machine
manufacturer.

For
fitting
on
the
crane
boom,
the
upper
part
of
the
rotator
is
equipped
with
a
coupling
fork,
with
a
fastening
pin
passed
inside
it
that
is
secured
with
a
safety
split
pin.
The
rotator
must
always
hang
free
vertically
with
respect
to
the
shaft.
Make
sure
to
limit
the
possibility
of
rotator
oscillation
and
protect
it
from
the
hydraulic
system
hoses
to
prevent
it
from
being
damaged.
6.2.2 Hydraulic connection
Make
sure
that
the
hydraulic
fluid
of
the
crane
is
clean
and
free
from
impurities,
optimal
filtration
10
μm.
The
hoses
that
control
the
rotation
must
be
connected
to
each
other
by
means
of
a
nipple
in
order
to
allow
the
circulation
of
the
fluid
for
at
least
5
minutes.
Subsequently,
the
hoses
are
connected
to
the
rotator
following
the
instructions
shown
by
the
symbols
situated
on
the
head
and
shaft
of
the
rotator.

The
hydraulic
system
of
the
crane
must
be
equipped
with
relief
valves
that
limit
the
pressure
to
the
required
250
bar,
and
the
flow
rate.
The
rotation
direction
of
the
rotator
and
the
movement
of
the
bucket
must
respond
to
the
indications
on
the
crane
controls.
The
crane
and
all
the
related
equipment
must
conform

6. INSTALLATION
6.1 Handling
For
lifting
and
transporting,
use
means
adequate
to
the
weight
to
be
moved.
To
ensure
safe
transport,
the
equipment
must
be
securely
fastened
onto
a
pallet.
Lifting
is
carried
out
together
with
the
pallet
using
a
lift
truck
or
by
harnessing
as
shown
in
the
figure,
providing
belts
with
a
suitable
capacity.
See
the
weight
of
the
components
indicated
in
Chapter
5
-
Technical
Characteristics.
Move
the
load
by
lifting
it
very
slowly
in
order
not
to
create
sudden
movements
that
could
give
rise
to
dangerous
situations.
The
personnel
assigned
to
moving
and
handling
must
wear:
protective
gloves,
hard
hat,
and
safety
shoes
with
steel
toe
and
non-skid
sole.
Make
sure
that
all
personnel
are
outside
the
range
of
action
of
the
lift
truck
during
the
operations
of
lifting,
transport,
and
handling.
Do
not
stand
below
suspended
loads
