Examine deficiencies <strong>and</strong> detennine whethera more detailed inspection is required.8.2.6Periodic Inspectiona. A qualified inspector shall perform acomplete inspection at the following intervals:1. Normal service-yearly.2. Heavy service-semiannually.3. Severe service-quarterly.b. The qualified inspector shall examinedeficiencies <strong>and</strong> determine whether they constitutea safety hazard <strong>and</strong> whether disassembly isrequired.c. Dated <strong>and</strong> signed inspection records shall bekept on file <strong>and</strong> shall be readily available.d. A sample load test <strong>and</strong> inspection form isincluded as Exhibit I, which appears at the end ofthis chapter. This form is intended to be a sampleonly <strong>and</strong> is not intended to be m<strong>and</strong>atory.8.2.6.1 Hoistsa. In addition to the requirements listed inSection 8.2.4, "Frequent Inspection," periodicinspections ofhoists shall include the following:1. Loose fasteners.2. Cracked or worn drums or sheaves.3. Worn, corroded, cracked, or distortedparts such as pins, bearings, shafts, gears, rollerslocking, <strong>and</strong> clamping devices.4. Excessive wear on motor or loadbrakes.5. Excessive wear ofchains, ropes,synthetic web strap, load sprockets, drums,sheaves, <strong>and</strong> chain stretch.6. Deterioration or damage ofendconnections <strong>and</strong> terminations ofwire rope, loadchains, <strong>and</strong> synthetic web.7. Hooks having more than 15 percent inexcess ofnormal throat opening, or more than 10degree twist from the plane ofthe unbent hook(see Chapter 13 for additional hook requirements).8. Hook-retaining nuts or collars <strong>and</strong>pins, welds, orriveting used to secure the retainingmembers. .9. Suitable crack-detecting inspectionsfor hooks, such as dye-penetrant ormagnetic-particle inspections (performed whenrequired by the inspector).10. Electrical apparatus for signs ofpittingor any deterioration ofcontroller contactors, limitswitches, <strong>and</strong> push-button switches.11. Supporting structures <strong>and</strong> trolleys, ifused, for continued ability to support the imposedloads.12. Warning labels for illegibility orabsence.8.2.6.2 Wire Ropea. A qualified inspector shall inspect runningrope at least annually. This inspection shallinclude examination ofthe entire length ofrope,without detaching it from the hoist drum. Morefrequent intervals shall be determined by aqualified person <strong>and</strong> shall bebased on suchfactors as expected rope life as determined byexperience on the particular installation or similarinstallations, severity ofenvironment, percentageofcapacity lifts, frequency rates ofoperation, <strong>and</strong>exposure to shock loads. The qualified inspectorshall carefully note any deterioration, such asdescribed below, resulting in appreciable loss oforiginal strength <strong>and</strong> determine whether furtheruse ofthe rope constitutes an acceptable risk.1. Reduction ofrope size below nominaldiameter, whether due to loss ofcore support,internal or external corrosion, or wear ofoutsidewires (see Table 8-1).8-9Chapter 8Hoists
