HOISTS
THAT
HAVE
BEEN
UNUSED
FOR
AN
EXTENDED
PERIOD
In
cases
where
the
crane
/
hoist
has
been
out
of
use
for
an
extended
period
of
time
the
user
should
ensure
that
the
competent
person
specifies
a
special
programme
of
pre
‐
use
checks.
The
extent
of
the
checks
depends
on
the
length
of
time
the
crane
has
been
out
of
service
and
the
location
of
the
crane
during
that
period.
As
a
minimum
the
pre
‐
use
checks
should
include
the
daily
pre
‐
start
inspections
mentioned
above
plus
the
following:
‐
1.
Check
all
ropes
for
signs
of
corrosion
/
degradation
and
damage
and
that
there
is
still
adequate
rope
lubricant.
Check
the
entire
length
of
the
rope.
2.
Check
that
the
RCL
(rated
capacity
limiter)
is
functioning
correctly.
3.
Check
for
corrosion
on
the
structure
and
mechanisms.
4.
Check
for
damage
and
missing
components
or
legends.
5.
Test
every
motion
for
several
minutes
without
load
ensuring
all
brakes
work
satisfactorily.
The
extended
period
of
time
should
be
determined
by
the
competent
person
and
will
depend
on
the
conditions
and
location.
As
a
minimum,
we
would
recommend
that
operations
1
to
4
above
are
carried
out
at
least
once
every
6
months,
and
operation
5
is
carried
out
monthly.
