- 11. CHAIN SLINGS
- 13. • Types of Web Slings: Nylon Polyester (Dacron) • Resistant to alkalis Resistant to many acids • Properties: • Relatively softness and broad width • Do not rust/Light weighted/softness precludes hand cuts • Used for polished and painted surface
- 14. TYPES OF SLINGS
- 15. TYPES OF SLINGS
- 16. LOADING OF WEB SLINGS
- 17. SLING SAFETY TIPS Never tie two or more slings together. Always connect two slings with a shackle.
- 18. SLING SAFETY TIPS Never attach a sling directly to a lifting lug. Be sure to choke below the threads on synthetic web slings.
- 19. SLING SAFETY TIPS Shackle Safety Tips Never allow the sling to bunch up on the shackle
- 20. Use washers to keep hook centered on shackle pin when necessary. SLING SAFETY TIPS
- 21. Example: 1” shackle and 1 ½” wire rope Shackle to Shackle Connection Example: 2” shackle and 1 ½” wire rope Always use the right size shackle SLING SAFETY TIPS
- 22. Too much tension on shackle ears. SLING SAFETY TIPS
- 23. Shackle pin can become unscrewed SLING SAFETY TIPS
- 24. Be sure to use the right size sling for the size of the hook. Be sure not to point load hooks. HOOK SAFETY TIPS

- 34. SAFE RIGGING PRACTICES KNOW HOW TO DO IT RIGHT! THEN DO IT RIGHT!
- 35. Standard Hand Signals For Controlling Cranes HOIST. With forearm vertical, forefinger pointing up, move hand in small horizontal circle LOWER. With arm extended downward, forefinger pointing down, move hand in small horizontal circle.
- 36. Standard Hand Signals For Controlling Cranes BRIDGE TRAVEL. Arm extended forward, hand open and slightly raised, make pushing motion in direction of travel. TROLLEY TRAVEL. Palm up, fingers closed, thumb pointing in direction of motion, jerk hand horizontally.
- 37. Standard Hand Signals For Controlling Cranes STOP. Arm extended, palm down, hold position rigidly. EMERGENCY STOP. Arm extended, palm down, move hand rapidly right and left.
- 38. MULTIPLE TROLLEYS. Hold up one finger for block marked “1” and two fingers for block marked “2”. Regular signals follow. MOVE SLOWLY. Use one hand to give any motion signal and place other hand motionless in front of hand giving the motion signal. (Hoist Slowly shown as an example.) Standard Hand Signals For Controlling Cranes
- 39. The rigging capacity and the material to be lifted must match. Using too small capacity rigging or components is just asking for an accident to happen. 1. Who is responsible (competent/qualified) for the rigging? a. Communications Established? RIGGING SELECTION
- 40. 2. Is the Equipment in Acceptable Condition? a. Appropriate Type? b. Proper Identification? C. Properly Inspected? RIGGING SELECTION
- 41. 3. Are the Working Load Limits Adequate? a. What is the weight of the load? b. Where is the center of gravity? c. What is the sling angle? d. Will there be side loading? e. Capacity of the gear? RIGGING SELECTION
- 42. RIGGING SELECTION 4. Will the Load be Under Control? a. Tag Line available? b. Is there any possibility of fouling? c. Clear of Personnel?
- 43. 5. Are there any Unusual Loading or Environmental Conditions? a. Wind? b. Temperature? c. Surfaces? (Ice, Suction, Water) d. Unstable Object(s)? RIGGING SELECTION
- 44. 2. Controllers will be placed in the “off” position. 3.The main switch will be placed in the “off” position or “open” position and LOCKED OUT, except where power is necessary to adjust or service the crane 4. A warning sign or “out of order” sign will be placed at the operator control station. 5. A Caution Board will be provided while maintenance is performed on the crane. Maintenance precautions 1. The crane will be moved to a location where it will cause the least interference with other moving equipment on the track or rails and operations in the area.
- 45. In the event of power failure @ The operator must place all controllers in the “off” position. @ When an operator leaves a crane unattended he must land any attached load. @ Place the controllers in the “off” position, and open the main switch. @ Before closing a main switch the operator must make sure all controllers are in the “off” position. @ The main switch does not need to be opened on a pendant-controlled crane if the crane is left unattended for short periods.
- 46. DETERMINE THE LOAD’S CENTER OF GRAVITY Center of gravity is the point within the load at which the object balances evenly in all directions. To ensure safe rigging it is important to identify the center of gravity so that the load will remain stable throughout the lift. The load should be raised directly above the center of gravity whenever possible.
