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 specific 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.
