. Inspection
Y. Inspection Y
is needed more often for heavily used hoists.
1.
Check operating mechanisms for proper
operation,
proper adjustment, and unusual
sounds
such as, but not limited to, binding noise
of the wire rope and bearing squeal.
2.
Check hoist upper limit device without a load on the
hook at the beginning of each shift. Exercise care.
Run
the
load
block into its limit device at slow speed.
3.
Frequent Braking System Inspection
a.
The braking system must automatically
stop and hold up to the rated
load if the
operating controls are
released
and in
the event of complete
power
failure
.
b.
Braking systems must limit the speed of load
during
lowering, with or without power, to
prevent
uncontrolled or rapid lowering.
4.
Frequent Hook Inspection
Check hooks for the following problems:
a.
distortion, such as bending, twisting,
or increased throat opening;
b.
wear;
c.
cracks, nicks, or gouges;
d.
latch engagement (if equipped);
e.
damaged or malfunctioning latch (if equipped);
f.
hook attachment and securing means.
5.
Frequent Hoist
Rope Inspection
All ropes should be visually inspected by the
operator
or other designated person at the start
of
each
shift.
These visual observations should be concerned with
discovering gross damage, such as listed
below,
which may be an immediate hazard:
a.
distortion of the rope such as kinking,
crushing, unstranding, birdcaging,
main
strand
displacement, or core protrusion;
b.
general corrosion;
c.
broken or cut strands;
d.
number, distribution, and type
of visible broken wires:
1)
in running ropes,
12 randomly distributed broken wires in one lay
or four broken wires in one strand in one
lay;
2)
one outer wire broken at the contact point
with the core of the rope which has worked its
way out of the rope structure and protrudes
or loops out from the rope structure.
If such damage is discovered, either remove the rope
from service or arrange for a qualified technician
to give it a periodic (thorough) inspection.
6.
Check wire rope reeving.
