(c) Electrical Equipment. External power supply, elec- trical equipment, and wiring for below-the-hook lifters shall comply with ANSI/NFPA 70 and ASME BTH-1. (d) Alterations. Structural and mechanical lifters may be altered or rerated, provided such alterations are ana- lyzed and approved by the equipment manufacturer or a qualified person. A rerated lifter, or one whose components have been altered, shall conform to para. 20-1.2.2 and be tested according to para. 20-1.3.8. New rated load shall be displayed in accordance with para. 20-1.2.1. (e) Slings, when employed, shall meet the require- ments of ASME B30.9. (f) Hooks, when employed, shall meet the require- ments of ASME B30.10. (g) Rigging hardware, whenemployed, shall meetthe requirements of ASME B30.26. 20-1.2.3 Installation (a) The lifter shall be installed in accordance with the manufacturer’s instructions. (b) The installer shall check for correct rotation of all motors. SECTION 20-1.3: INSPECTION, TESTING, AND MAINTENANCE 20-1.3.1 Inspection Classification (a) Initial Inspection (1) New and reinstalled lifters shall be inspected by a designated person prior to initial use to verify compliance with applicable provisions of this Volume. (2) Altered or repaired lifters shall be inspected by a designated person. The inspection may be limited to the provisions affected by the alteration or repair, as determined by a qualified person.
(3) Periodic Inspection. Visual inspection by a quali- fied person making records of apparent external condi- tions to provide the basis for a continuing evaluation. An external code mark on the lifter is an acceptable identification in lieu of records. (a) Normal service for equipment in place — yearly (b) Heavy service [as in (a) above, unless external conditions indicate that disassembly should be done to permit detailed inspection] — semiannually (c) Severe service [as in (b) above] — quarterly (d) Special or infrequent service — as recom- mended bya qualified personbefore the firstsuchoccur- rence and as directed by the qualified person for any subsequent occurrences 20-1.3.2 Every Lift Inspection Items such as the following shall be inspected by the operator before and/or during every lift for any indica- tionofdamage as specificallyindicated,includingobser- vations during operation for any damage that might occur during the lift: (a) surface of the load for debris (b) condition and operation of the controls (c) condition and operation of the indicators and meters when installed 20-1.3.3 Frequent Inspection (See Also Table 1) Items such as the following shall be inspected for damage at intervals as defined in para. 20-1.3.1(b)(2), including observations during operation for any indica- tions of damage that might appear between inspections. A qualified person shall determine whether any indica- tions of damage constitute a hazard or will require more frequent inspection. For all lifters, inspect (a) structural members for deformation, cracks, or excessive wear on any part of the lifter (b) loose or missing guards, fasteners, covers, stops, or nameplates (c) all functional operating mechanisms and auto- matic hold-and-release mechanisms for misadjustments interfering with operation
(b) Theloadtest, ifmade,shallconsistofthefollowing operations as a minimum requirement: (1) Hoist the test load a sufficient distance to ensure the load is supported by the lifter, or apply the required load if the test is made using a testing machine. (2) After the test load is released, visually inspect the lifter for deformation, cracks, or other defects. (c) Tests of altered or repaired lifters may be limited to the provisions affected by the alteration or repair, as determined by a qualified person with guidance from the manufacturer. 20-1.3.9 Maintenance (a) Maintenance Program. A maintenance program shall be established and be based on recommendations made by the lifter manufacturer. If a qualified person determines it is appropriate, the program should also include that individual’s additional recommendations based on a review of the lifter application and operations. (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.
