SAFETYOPERATIONINSPECTION INSTALLATION
7.
Check electrical apparatus for evidence of
pitting or deterioration of controller contacts.
8.
Check supporting structure or trolley,
if
used, for evidence of damage.
9.
Check warning label for legibility and replacement.
10.
Check end connections of wire ropes for evidence
of wear, corrosion, cracks, damage, and distortion.
11.
Periodic (Thorough) Hoist Rope Inspection
Check entire length of rope hoist rope as follows:
Inspect the individual outer wires in the strands
of the rope. Keep a record of any deterioration
resulting in appreciable loss of original strength,
such as described below, and have a qualified
technician determine whether further use
of the rope would constitute a hazard:
a.
Check points listed in Frequent
Hoist
Rope Inspection on page
8
.
b.
Check for reduction of rope diameter
below nominal diameter due to loss of
core
support, internal or external
corrosion,
or wear of outside wires.
c.
Check for severely corroded or broken
wires at end connections.
d.
Check for severely corroded, cracked, bent,
worn, or improperly applied end connections.
e.
Inspect with special care the following
sections of rapid deterioration:
1)
sections in contact with saddles,
equalizer pulleys, or other pulleys
where rope travel is limited;
2)
sections of the rope at or near terminal ends
where corroded or broken wires may protrude;
3)
sections subject to reverse bends;
4)
sections of rope which are normally
hidden during visual inspection, such
as parts passing over pulleys.
12.
Check function labels on pendant
control(s) for legibility.
13.
Check the hoist and hoist mounting
for evidence of missing parts.

HOIST FAILURE:
Do not use damaged equipment.
If
any defect or damage is noted, have the problem corrected before further use.
Storage Inspection
1.
A hoist that has been idle for a period of
a month or more, but less than a year,
must
be
inspected before being used according
to the Frequent Inspection requirements.
2.
A hoist that has been idle for a period of a
year or more, must be inspected according
to the Periodic Inspection requirements and
then tested according to the procedure in the
Testing section below before being used.
Maintenance
1.
Repair or replacement of hoist components must be
performed only
by
a
qualified
technician using
only
identical replacement parts with the same rating.
2.
Operating mechanisms
,
limit switches, control
systems,
and brakes may require adjustment.
3.
Note
the
following
regarding
specic
components:
a.
Replace damaged or worn
hooks. Do
not
repair
them by welding or reshaping.
b.
Replace or repair all critical parts that are cracked,
broken, bent, excessively worn, or missing.
c.
Replace missing or illegible warning labels.
d.
Replace pitted or burned
electrical
contacts as complete sets.
e.
Keep controller function labels on pendant
control stations and master switches legible.
4.
Do not repair load
-
sustaining members by welding.
Replace them as needed.
5.
Lubricate all moving parts regularly using grease.
6.
After maintenance work is completed and before
restoring the hoist to normal operation:
a.
reinstall guards;
b.
reactivate safety devices;
c.
remove replaced parts and loose material;
d.
remove maintenance equipment.
Testing
1.
Before use, test repaired hoists and hoists that
have not been used for a year or more.
2.
Check all functions of the hoist, including
lifting
and lowering
, with the hoist unloaded
first.
3.
After testing in the unloaded state,
attach
a
200
Ib.
load and retest to check proper
load
control and to check brake operation.
4.
Test the trip-setting of limit devices under no
-
load
conditions. Test first by hand, if practical, and
then under slowest speed. Test
with increasing
speeds up to maximum speed. Check that
actuating mechanisms are located so that
they will trip the switches or limiting devices
in sufficient time to stop motion without
causing damage to any part of the
hoist.
