ASME B30.20 Inspection Standards
ASME B30.20 requires that the user of below-the-hook lifting devices maintain their lifters in good working order, which ultimately protects the user from exposure to liability and unsafe working environments (according to OSHA 2232.) Not only does ASME B30.20 require maintenance of the lifting device, it also requires that inspection be done by a qualified inspector. A qualified inspector is a person who, by possession of a recognized degree in an applicable field or certificate of professional standing, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work (Section 20-.02 of ASME B30.20). Tandemloc's inspectors are certified and qualified to visually inspect your product by the standards set by ASME B30.20, AWS D14.1, and SNT-TC-1A.
- Frequent Inspection - Items such as the following shall be inspected for damage at intervals as defined in paragraph 20-1.3.1(B)(2), including observations during operation for any indications of damage that might appear between inspections. A qualified person shall determine whether any indications of damage constitute a hazard or will require more frequent inspection. For all lifters, inspect:
- Structural members for deformation, cracks, or excessive wear on any part of the lifter.
- Loose or missing guards, fasteners, covers, stops, or nameplates.
- All functional operating mechanisms and automatic hold-and-release mechanisms for maladjustments interfering with operation.
- Periodic Inspection - Items such as the following shall be inspected for damage at intervals as defined in paragraph 20-1.3.1(B)(2), including observations during operation for any indications of damage that might appear between inspections. A qualified person shall determine whether any indications of damage constitute a hazard or will require more frequent inspection. For all lifters, inspect:
- Loose bolts or fasteners.
- Cracked or worn gears, pulleys, sheaves, sprockets, bearings, chains, and belts.
- Excessive wear of friction pads, linkages, and other mechanical parts; and
- Excessive wear at hoist hooking points and load support clevises or pins
- Load Test
- Prior to initial use, all new, altered, modified, or repaired lifting devices should be tested and inspected by, or under the direction of, a qualified person, and a written report be furnished by such a person, confirming the load rating of the lifter. The load rating should not be more than 80% of the maximum load sustained during the test. Test loads shall not be more than 125% of the rated load unless otherwise recommended by the manufacturer. Test reports should be available.
- The load test, if made, shall consist of the following operations as a minimum requirement.
- Hoist the test load at a sufficient distance to ensure the load is supported by the lifter, or apply the required load if the test is made using a test machine.
- After the test load is released, visually inspect the lifter for deformation, cracks, or other defects.
- Altered, repaired, or modified lifters shall be tested by a qualified person or a designated person under the direction of a qualified person. This test may be limited to the provisions affected by the alteration, repair, or modification, as determined by a qualified person with guidance from the manufacturer.
- Maintenance
- Maintenance Program. A maintenance program should be established and be based on recommendations made by the lifter manufacturer or a qualified person with guidance from the manufacturer.
- Maintenance Procedure:
- Before adjustments and repairs are started on a lifter, the following precautions shall be taken.
- A lifter removed from service for repair shall be tagged "Out of Service."
- Only qualified persons shall perform adjustments and tests when required.
- Replacement parts shall be obtained from TANDEMLOC, Inc.
- After adjustments and repairs have been made, the lifter shall not be returned to service until it has been inspected according to paragraph 20-1.3.4.
- Dated records of repairs and replacements should be made.
- Adjustments and Repairs. Any hazardous conditions disclosed by the inspection requirements of paragraph 20-1.3.1 shall be corrected before normal operation of the lifter is resumed. Adjustments and repairs shall be done under the direction of, or by, a qualified person.
