Prior to their initial use, all forklifts in whichload-sustaining parts have been modified,replaced, or repaired shall be load-tested by aqualified inspector or under the direction ofthatinspector.1. Test loads shall not exceed100 percent ofthe rated capacity.2. Test weights shall be accurate towithin -5 percent. +0 percent ofstipulated values.3. Load slippage shall not be greater than3 in. vertically <strong>and</strong> 1 in. horizontally at thecylinder during a static test of at least 10 minduration.4. Load-test records shall be maintained<strong>and</strong> shall be made available for examination bythe construction management contractor.b. A load test shall not be conducted inlocations such that the lift meets the definition ofcritical lift in Section 15.2.15.4.6 Slings-Inspection15.4.6.1 Wire Ropea. Users or other designated personnel shallvisually inspect all wire-rope slings each day priorto use, carefully noting any deterioration thatcould result in an appreciable loss of originalstrength <strong>and</strong> determining whether further use ofthe sling would constitute a safety hazard.b. Slings shall be immediately removed fromservice ifany ofthe following conditions arepresent:1. Ten r<strong>and</strong>omly distributed broken wiresin one rope lay, or five broken wires in one str<strong>and</strong>in one rope lay.2. Wear or scraping ofone-third theoriginal diameter ofoutside individual wires.3. Kinking. crushing, birdcaging. or anyother damage resulting in distortion ofthe ropestructure.4. Evidence ofheat damage from anycause.5. End attachments that are cracked.deformed. or worn.6. Hooks thathave been opened morethan 15 percent ofthe normal throat openingmeasured at the narrowest point or twisted morethan 10 degrees from the plane of the unbenthook.7. Corrosion ofthe rope or endattachments.15.4.6.2 Synthetic Web Slingsa. Users or other designated personnel shallvisually inspect all synthetic-web slings each dayprior to use. carefully noting any deterioration thatcould result in an appreciable loss oforiginalstrength <strong>and</strong> determining whether further use ofthe sling would constitute a safetyhazard.CAUTION: Tiedown <strong>and</strong>/or ratchet straps shallnot be used as synthetic-web slings. Onlysynthetic-web slings constructed from webbingapproved for sling construction by themanufacturer or other qualified person shall beused at <strong>DOE</strong> locations.b. A synthetic-web sling shall be removed fromservice ifany ofthe following defects are visible:1. Acid or caustic burns.2. Melting or charring ofany part ofthesurface.3. Snags, punctures. tears. or cuts.4. Broken or worn stitches.5. Wear or elongation exceeding theamount recommended by manufacturers.6. Distortion offittings.c. For other apparent defects that cause doubtas to the strength ofthe sling, refer to themanufacturer for determination ofwhethercontinued use would constitute a safety hazard.15.4.6.3 Alloy Steel Chaina.
