1. Overhead Crane General Use & Inspection Criteria The Selection Process For Both Overhead Cranes & Underhung Hoists, Should Not Be Taken Lightly. A Significant Amount Of Pre-planning Is Needed To Place The Proper Crane Or Hoist Into The Proper Environment. The Key To Equipment Longevity Is Complete And Through Inspections

2. Different Equipment Types Overhead Cranes Gantry, Semi-gantry, Bridge, Cantilever etc Underhung Hoist Monorail, Underhung Bridge, Wall jib, Floor jib, etc Electric, Air (pneumatic), Manual powered

3. Duty Cycle Classes There Differences Between Overhead and Underhung Crane Classifications

4. Duty Cycles - Overhead Cranes CMAA spec 70 ASME B30.2

5. Duty Cycles - Overhead Cranes There are six Service Class designations for the Overhead Cranes based on their Load Class and Load Cycles. Class A – F Class A – Standby or Infrequent Service Class B – Light Service Class C – Moderate Usage Class D – Heavy Service Class E – Severe Service Class F – Continuous Severe Usage

6. Duty Cycles - Underhung Hoists CMAA spec 74 ASME B30.16

7. Duty Cycles – Underhung Hoists There are four Service Class designations for the Overhead Cranes based on there Load Class and Load Cycles. Class A – D Class A – Standby or Infrequent Service Class B – Light Service Class C – Moderate Usage Class D – Heavy Service

8. Duty Cycle & Maintenance Cost Placing Class B Crane Into A Class C Environment is Tantamount to …. Flushing Your Maintenance Dollars Down The Toilet!

9. Overhead Crane Inspections There Are Two Reasons For The Correct And Timely Performance Of Inspections, And Testing On Overhead Cranes. 9

10. Overhead Crane Inspections Humanitarian Decrease The Probability For Equipment Failures That Result In Personnel Injuries/Death. Provide A Safer Working Environment For All Workers. 10

11. Overhead Crane Inspections Economic Increased Productivity. Decrease Repair & Replacement Cost. 11

16. INSPECTION REQUIREMENTS Federal - General Industry Initial (29 CFR 1910.179 (j) (1)) Regular (29 CFR 1910.179 (j) (2)) Frequent: 29 CFR 1910.179 (j) (2) and ASME B30.2 Periodic: 29 CFR 1910.179 (j) (3) and ASME B30.2 16

17. INSPECTION REQUIREMENTS Federal – Construction Permanently Installed Cranes Exempted 1926.1438 17

18. INSPECTION REQUIREMENTS Federal – Construction Non-Permanently Installed Overhead Cranes Used in Construction Must comply with the following: Modified Equipment (1926.1412 (a)) Repaired/Adjusted Equipment (1926.1412 (b)) Post-assembly (1926.1412 (c)) Each Shift (1926.1412 (d)) Monthly (1926.1412 (e)) Annual/Comprehensive (1926.1412 (f)) Severe Service (1926.1412 (g)) Equipment Not In Regular Use (1926.1412 (h)) 18

19. INSPECTION PROCESS Inspections may be broken down into systems, i.e. Mechanical –Brakes (not including the actuators) –Brake lining –Gear Box(s) –Drive (End) Trucks –Drive Shafts, etc. Structural –Runway –Rails –Bridge Girders, etc. 19

20. INSPECTION PROCESS Inspections may be broken down into systems, i.e. Electrical –Motors –Controllers –Brake actuators –Buss Bars –Electrical Cabinets, etc. Hydraulic/Pneumatic –Brake Actuators –Master Cylinder, etc. 20

21. INSPECTION PROCESS 21 Drive Wheel, Gearbox & Driveshaft Mechanical Inspection

22. INSPECTION PROCESS 22 Brake Lining, Drums & Components Mechanical Inspection

23. INSPECTION PROCESS 23 Catwalk & Driveshaft Alignment & Mounting Mechanical Inspection

24. INSPECTION PROCESS 24 Gear Box Inspection Mechanical Inspection

25. INSPECTION PROCESS 25 Runway & Rails Structural Inspection

26. INSPECTION PROCESS 26 Support Column Alignment & Missing Hardware Structural Inspection

27. INSPECTION PROCESS 27 Bumpers & End Stops Structural Inspection

28. INSPECTION PROCESS 28 Confirm Square of Bumpers &Rails Structural Inspection

29. INSPECTION PROCESS 29 Wiring and Wire Terminations Electrical Inspection

30. INSPECTION PROCESS 30 Hoist Motor Electrical Inspection

31. INSPECTION PROCESS 31 Collectors & Conductors Electrical Inspection

32. INSPECTION PROCESS 32 Hydraulic Brake for Leakage Hydraulic/Pneumatic Inspection

33. REQUIREMENTS FOR LOAD TESTING Operational Tests and Rated Load Tests: Initial Installation (NEW) After Alterations, Repairs Or Modifications 29 CFR 1910.179 (K) (1) ASME B30.2-2.1 And 2-2.2.2 Some State OSHAs Require Load Testing 33

34. DOCUMENTATION Required Annual Monthly On Critical Items And Running Rope 34

35. DOCUMENTATION Recommended Documentation And Retention Time Daily (Current And Previous Month) Weekly (Latest Plus Previous 4) Monthly/Quarterly (Latest Plus Previous Year) Semi-annual/Annual (Latest Plus Previous Year) Others (Latest Plus Previous Year) 35

36. DOCUMENTATION Required Documentation And Retention Time Per 29 CFR 1926 Subpart CC Monthly (29 CFR 1926.1412 (e)(3) (document must be retained for a minimum of three months) Annual (29 CFR 1926.1412 (f)(7) (document must be maintained and retained for a minimum of 12 months) 36

37. Maintains A Complete Inspection, Maintenance, And Testing History Of The Equipment. Allows End User To Establish Life Cycle Cost. Assist In Establishing Trend Analysis. 37 DOCUMENTATION

38. DOCUMENTATION Can Establish Requirements For On-hand Spare Parts To Decrease Replacement Lead Time Provides Statistical Data To Predict Mean Time Between Failure (MTBF) Provides Statistical Data To Predict Mean Time To Repair (MTTR) To Defend Against Liability 38

39. STORAGE OF DOCUMENTATION Documents should be stored in a place where they are readily available. All workers, most importantly the operator, should know where these papers are. 39

40. SUMMARY The Inspection And Testing Of Overhead Cranes And Hoists Is Crucial To Safe Workplace Conditions. Any Kind Of Equipment Begins Depreciating After Its First Use. A Defect In Equipment Can Bring A Quick End To The Day, In A Best-case Scenario. 40
