### Slingsafety 1226191517188739-8

1. 1. Sling Safety Presented by Bill Taylor
2. 2. Objectives • Be familiar with OSHA’s regulations regarding slings. • Understand safe sling use. • Be able to identify and describe conditions necessitating sling’s replacement.
3. 3. Slings • OSHA Part 29 CFR 1910.184 Defines a sling as : • An assembly which connects the load to the material handling (lifting) equipment
4. 4. Frequency of Inspections All slings are to be inspected prior to their use. This includes chain, wire rope and synthetic slings and their attachments, i.e. master links, alligators, clips, hooks, quick-alloys etc.. A thorough plant-wide inspection is required to be performed at least once every 12 months.
5. 5. Hitches
6. 6. Load Capacity and Sling AnglesLoad Capacity and Sling Angles The load capacity of the sling is determined by its weakest component. Never Overload a Sling. Remember, the wider the sling legs are spread apart, the less the sling can lift! 1000 lbs Capacity 707 lbs Capacity 500 lbs Capacity
7. 7. Load Capacity and Sling AnglesLoad Capacity and Sling Angles Example: Choker rating of each sling = 6,000 lbs. Measured Length (L) = 6 ft. Measured Height (H) = 4 ft. Reduction Factor (RF) = 4 (H) ÷ 6 (L) = .667 Reduced sling rating in this configuration = .667(RF) x 6,000 lbs. = 4,000 lbs. of lifting capacity per sling
8. 8. Three Types of Slings Wire Rope Slings Chain Slings Synthetic Web Slings
9. 9. Chain Slings
10. 10. Chain Slings Only chain slings purchased from the manufacturer are allowed. No homemade slings allowed!!
11. 11. Chain Sling Inspection Items  Cracks, stretches, nicks, gouges, welding splattered or deformed master links  One leg of a double or triple chain sling is longer than the others.  Hooks have been opened more than 25% of the normal throat opening measured at the narrowest point or twisted more than 10 degrees from the plane of the unbent hook.  Chain size at any point of any link is less than stated in the chart on the next slide, the sling shall be removed.
12. 12. Special Precautions • Chain slings should never be modified or repaired by operators! Only qualified maintenance personnel may do so. • It is important to realize that the capacity of a sling decreases as the angle at which it is used to lift increases.
13. 13. Wire Rope Slings
14. 14. Wire Rope Sling Inspection Items  Three randomly distributed broken wires in one strand, in one rope lay. Wear or scraping of 1/3 the original diameter of outside individual wires. Kinking, crushing or any damage resulting in distortion of the wire rope. End attachments that are cracked, worn or deformed. Corrosion of the rope or end attachments.
15. 15. Polyester Round Slings Codes and Capacities
16. 16. Synthetic Web Sling Inspection Acid or caustic burns on the sling. Melting or charring of any part of the sling’s surface. Snags, punctures, tears, or cuts. Stitching is broken or worn. The sling is stretched. To assist operators in determining if a sling is stretched, manufacturers incorporate a red wear cord inside of the sling. When this red wear cord can be readily seen upon inspecting the sling, the sling has been stretched and is to be removed.
17. 17. Safe Usage Practices Slings should be stored off the floor and in a clean, dry place. Always hook with a closed hook arrangement hooks facing out. Never drag slings across the floor.
