37 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Position bridge and trolley directly over load. Ensure hoist line vertical. Lower hook to attach sling. Ensure sling properly balanced and controlling load. Do NOT tie knots in sling. Position Crane & Attach Sling

38 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Load Balance Unbalanced load creates greater force on sling than actual weight of load. Angle Angle of sling reduces capacity. Load Movement Rapid, sudden movements result in increased forces due to dynamic loading. 3 Factors Affecting Capacity

39 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Flagman and crane operator must understand each other. Operator responds only to signals from designated flagman. Flagman must be in constant communication with operator. When a flagman is not required, the operator is responsible for movement of crane. Hand Signals

42 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Notify co-workers before lifting and moving load. Operator must be positioned so that: –Load is in view. –There are no potential pinch points. STOP if any concern about safety. Notifying Others & Positioning Self

43 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Keep both hands on pendant control. Use pendant to control all movement: –Forward and back. –Left and right. –Up and down. Electric brake will set if release control button. Using Pendant Control

44 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Always lift straight up. Raise load high enough to clear obstacles. NEVER put hands between load and sling. Ensure co-workers properly positioned. Check intended path. Lifting Load

45 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C If load being handled is close to rated load. Check hoist brakes once per shift: –Raise load short distance. –Apply brakes. –Observe load for slippage. –Observe drum for turning. Lifting Loads near Rated Load

68 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Using Appendix C, complete a performance evaluation by conducting a pre-operational inspection and by safely operating a pendant- controlled crane to lift, move and set a load. Objective 11

69 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Instructor demonstration. Time for student practice. Students may perform inspection in pairs but must independently lift, move, and land load. While one student operates crane, another student attaches load and gives hand signals to operator. Students then reverse roles. Each student must independently complete Appendix C. Performance Evaluation

70 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C Industry Event Appendix A, Operating Experience OE14316, Failure of Upper Limit Switch Causes Fuel Cask Auxiliary Hook and Block to Fall 70 Feet Summary: On June 4, 2002, with Salem Unit 1 at 100 percent power and following crane activities in the fuel building, a crane operator performed activities to stow the pendant operated 3-ton rated auxiliary hook on the fuel cask crane. The crane operator raised the hook, relying on the anti two-block switch to stop the auxiliary hoist movement. The switch failed and the hook continued to rise, snapping the cable. The block and hook fell 70 feet to the floor. The cause of the event was a failure of the hoist upper limit switch. Follow-up testing indicated the switch would intermittently fail. Human performance deficiencies contributed to the event in that the crane operator did not inch the hoist into the upper limit switch at a very slow speed as directed by training and procedure and he relied on the upper limit switch as a stop control during normal operation. Corrective actions include adjusting the hoist brake, inspecting the block and hook, load testing hoist after reassembly, testing Unit 2 crane's limit switch, and inspecting other cranes limit switches. Future corrective actions include replacing the hoist cable, revising training lesson plans to emphasize not to rely on the limit switches to stop, and evaluating the installing an additional limit switch to both unit's cask handling cranes. This event is not significant because there was no damage to other equipment or personnel injury. This event is NOTEWORTHY because of the potential for serious personnel injury and equipment damage.

71 Crane Safety (Pendant) Safety Training Technical Training NEXTNEXT PREVPREV A B C 11 Appendix B What should you know about using synthetic web slings? 1. Synthetic web slings are easily cut and have poor abrasion resistance when compared with chain and wire rope slings. 2. Nylon slings are damaged by acids, but resist caustics. 3. Polyester slings are damaged by caustics but resist acids. 4. Sunlight, moisture, and temperatures above 90°C (194°F) damage both nylon and polyester slings. 5. Use slings made of the right material for the job. 6. Check the manufacturers' slings for code number and rated capacity. Reference charts showing slings and hitch rated capacities are available from manufacturers. 7. Inspect slings before using them. 8. Keep an inspection record for each sling. What should you check when selecting slings? 1. Refer to the manufacturer's reference chart for the capacity rating. 2. Check a sling before using it. 3. Determine the weight of the load. 4. Prevent loading more than the rated capacity by considering sling angle. 5. Protect webbing from sharp corners, protrusions, or abrasive surfaces. 6. Ensure that the sling choking action is on the webbing, not the hardware. 7. Have slings repaired by a sling manufacturer only. What should you avoid when using slings? 1. Do not drag slings across floors or other abrasive surfaces. 2. Do not drop slings with metal fittings. 3. Do not set loads down on top of slings. 4. Do not pull slings from under loads when the load is resting on the sling. 5. Do not weld anything hung from a sling. 6. Do not lengthen or shorten slings by tying knots. 7. Do not place stitch patterns (laps) on hooks, sharp corners, or choker bearing points. What kinds of damage make a synthetic web-sling unusable? 1. Increased stiffness of sling material. 2. Acid or caustic burns. 3. Melted, burned or weld spatter damage. 4. Holes, tears, cuts, snags. 5. Broke or worn stitching. 70
