(d)  excessive wear at hoist hooking points and loadsupport clevises or pins

(e)  missing or illegible product safety labels required by para. 20-1.2.1(d)

20-1.3.5 Lifting Devices Not in Regular Use

A lifter that has been idle for a period of 1 mo to1 yr shall be inspected in accordance with para. 20-1.3.3 before being placed in service. A lifter that has beenidle for a period of 1 yr or more shall be inspected inaccordance with para. 20-1.3.4 before being returned toservice.

20-1.3.6 Inspection Records

Dated inspection reports shall be made on criticalitems such as those listed in para. 20-1.3.4. Recordsshould be available for each periodic inspection andwhen the lifter is either altered or repaired.

20-1.3.7 Repairs

Anyindications of damage disclosedby theinspectionrequirements of Section 20-1.3 shall be correctedaccording to the procedures outlined in para. 20-1.3.9 before operation of the lifter is resumed.Repairs of slings(ASME B30.9), hooks (ASME B30.10), rigging hardware(ASME B30.26), or other special devices shall complywith repair requirements in the applicable volumes orstandards.

20-1.3.8 Testing 

20-1.3.8.1 Operational Tests(a)  New and reinstalled lifting devices shall be tested

 by a qualified person, or a designated person under thedirection of a qualified person, prior to initial use toverify compliance with applicable provisions of thisVolume, including, but not limited to, the following:

(1) Moving Parts.  Lifters with moving parts shall betested to determine that the lifter operates in accordancewith manufacturer’s instructions.

(2) Latches.   Lifters with manually operated or auto-matic latches shall be tested to determine that the latch

operates in accordance with manufacturer’sinstructions.

(b)   Altered or repaired lifters shall be tested by aqualified person, or a designatedperson under thedirec-tion of a qualified person. This test may be limited tothe provisions affected by the alteration or repair, asdetermined by a qualified person with guidance fromthe manufacturer.

(c)   All indicator lights, gages, horns, bells, alarms,pointers, and other warning devices shall be tested.

(d)   Dated reports of all operational tests shall be filed.

20-1.3.8.2 Load Test(a)   Prior to initial use, all new, altered, or repaired

lifting devices should be tested and inspected. If per-formed, tests shall be done under the direction of aqualified person and a written report be furnished bysuch a person, confirming the load rating of the lifter.The load rating should not be more than 80% of themaximum loadsustainedduring thetest. Testloads shallnot be morethan 125% of the rated load unless otherwiserecommended by the manufacturer. Test reports should be available.

(b)   Theload test, if made, shall consist of thefollowingoperations as a minimum requirement:

(1)   Hoist the test load a sufficient distance to ensurethe load is supported by the lifter, or apply the requiredload if the test is made using a testing machine.

(2)  After the test load is released, visually inspectthe lifter for deformation, cracks, or other defects.

(c)  Tests of altered or repaired lifters may be limitedto the provisions affected by the alteration or repair, asdetermined by a qualified person with guidance fromthe manufacturer.

20-1.3.9 Maintenance

(a) Maintenance Program.  A maintenance programshall be established and be based on recommendationsmade by the lifter manufacturer. If a qualified persondetermines it is appropriate, the program should alsoinclude that individual’s additional recommendations ba sed on a revi ew of th e li ft er ap pl ic at io n an doperations.

(b) Maintenance Procedure(1)  Before adjustments and repairs are started on a

lifter, the following precautions shall be taken:(a)  All sources of power shall be disconnected,

locked out, and tagged “Out of Service.”(b)  A lifter removed from service for repair shall

 be tagged “Out of Service.”(2)  Only qualified persons shall perform adjust-

ments and tests when required.(3)  Replacement parts shall be at least equal to the

original manufacturer’s specifications.(4)  After adjustments and repairs have been made,

the lifter shall not be returned to service until it has been inspected according to para. 20-1.3.4.
