DOE-STD-I090-96 (Rev-I)7.2.5 Monthly Rope, Chain,and Hook Inspectiona. The operator or other designated personshall visually inspect the following items fordamage, wear, or other deficiency that mightreduce capacity or adversely effect the safety ofthe crane:7.2.61. hoist rope or chain2. hooksb. Lower the hook block to its lowest positionand examine for any condition that could result inan appreciable loss ofstrength.IIc.. Hoist rope for significant wear, kinking, Icrushing, birdcaging, and corrosion.IId. Hoist chain for nicks, gouges, distortion, Iwear, and corrosion.IIe. Hooks for cracks, deformation, damage from Ichemicals, latch engagement (ifprovided), andevidence ofheat damage.f. Signed and dated inspection records shall be Ikept on ftle and shall be readily available.g. Before the crane is returned to service,correct deficiencies that could reduce its capacityor adversely effect its safety.Frequent Inspectiona Operators or other designated personnelshall visually inspect the crane at the followingintervals (records are not required):1. Normal service-monthly.2. Heavy service-weekly to monthly.3. Severe service-daily to weekly.b. ill addition to the requirements ofSection 7.2.4, "DailyPreoperational Check," theseinspections shall include the following:1. Hoist braking system for properoperation.2. Hoist rope or chain reeving forcompliance with hoist manufacturer'srecommendations.III7.2.73. Observations during operation.c. Operators or other designated personnelshall examine deficiencies and determine whethera more detailed inspection is required.Periodic 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 and determine whether they constitutea safety hazard and whether the crane should beremoved from service until it is repaired:c. Dated and signed inspection records shall bekept on ftle and shall be readily available.d. A sample load test and inspection form isincluded as Exhibit I, which appears at the end ofthis chapter. This form is intended to be a sampleonly and is not intended to be mandatory.7.2.7.1 Cranesill addition to the requirements ofSection 7.2.6,''Frequent fuspections," periodic inspections shallinclude the following:a. Components for deformation, cracks, orcorrosion.b. Bolts, rivets, nuts, and pins for being looseor absent.c. Sheaves and drums for cracks or wear.d. Parts such as pins, bearings, shafts, gears,rollers, locking and clamping devices, bumpers,and stops for wear, cracks, or distortion.e. Brake-system parts, linings, pawls, andlatches for excessive wear.f. Load, wind, and other indicators over theirfull range for any significant inaccuracies.g. Gasoline, diesel, electric, or other powerplants for improper performance ornoncompliance with other applicable standards.7-7Chapter 7Overhead and Gantry Cranes
DOE-STD-I090-96 (Rev-I)h. Chain-drive sprockets for excessive wearand chains for excessive stretch.i. Electrical apparatus for signs ofanydeterioration ofcontrollers, master switches,contacts, limit switches, and push-button stations(not limited to these items).j. Hooks for damage from chemicals,deformation, cracks, orhaving more than15 percent in excess ofnormal throat operating, ormore than 10 degree twist from the plane oftheunbent hook (see Chapter 13 for additional hookrequirements).k. Hook retaining nuts or collars and pins,welds, or riveting used to secure the retainingmembers for soundness.l. Nondestructive examination ofhooks and ofwelds, bearings, or other suspect load-bearingparts when required by the inspector.In. Testing ofmotion limit devices, whichinterrupt power or cause a warning to be activated,for proper performance (each motion shall beinched or operated at low speed into the limitdevice with no load on the crane).n. Function labels for legibility.7.2.7.2 Wire Ropea. A qualified inspector shall inspect all ropesat least annually. This inspection shall includeexamination ofthe entire length ofthe rope,without detaching it from the hoist drum. Morefrequent intervals shall be determined by aqualified person and shall be based on suchfactors as expected rope life as determined byexperience on the particular installation or similarinstallations, severity of environment, percentageof capacity lifts, frequency rates ofoperation, andexposure to shock loads. The qualified inspectorshall carefully note any deterioration such asdescribed below resulting in appreciable loss oforiginal strength and determine whether furtheruse ofthe rope constitutes an acceptable risk.1. Reduction ofrope size below nominaldiameter, whether due to loss of core support,internal or external corrosion, or wear of outsidewires (see Table 7-1).Table 7-1. Maximum allowable ropereductions.Rope diameterUp to 5/16 in.(8 mm)Over 5/16 in. to1/2 in. (13 mm)Over 1/2 in. to3/4 in. (19 mm)Over 3/4 in. to1 1/8 in. (29 mm)Over 1 1/8 in. to1 1/2 in. (38 mm)Maximum allowablereductionfrom nominal diameter1/64 in. (0.4 mm)1/32 in. (0.8 mm)3/64 in. (1.2 mm)1/16 in. (1.6 mm)3/32 in. (2.4 mm)2. The number and distribution orconcentration ofbroken outside wires.3. Worn outside wires.4. Sections ofrope that are normallyhidden during inspection or maintenance procedures,such as parts passing over sheaves (theseare points most subject to deterioration).5. Corroded or broken wires at endconnections.6. Corroded, cracked, bent, worn, orimproperly applied end connections.7. Kinking, crushing, cutting, orunstranding.b. All rope on cranes that have been idle for 1month or more due to shutdown or storage shallbe inspected before the crane is returned toservice. A dated and signed report ofthe ropeinspection, including results, shall be filed.c. No precise rules can be given fordetermining the exact time to replace rope becausemany variables are involved. Safety in thisrespect depends largely on the use ofgoodjudgment by an appointed person in evaluatingremaining strength in a used rope, after allowancefor deterioration disclosed by inspection. Safetyofrope operation depends on this remainingstrength.Chapter 7Overhead and Gantry Cranes 7-8
