Course Objectives Describe operator responsibilities and potential hazards when operating a pendant-controlled crane. Review ANSI Hand Signals Related to Pendant Cranes 11. Using Appendix C, complete a performance evaluation by conducting a pre-operational inspection and safely operating a pendant-operated crane to lift, move, and set a load.
Identify certification and recertification requirements for pendant-controlled crane operators. Objective 1
Prior to operating pendant crane: Training (00059112) Knowledge eval (80%) Performance eval (100%) Retraining required every 3 years. Certification Requirements for Pendant Crane Operators
Define the following crane terms: runway, bridge, trolley, hoist, hoist drum, hoist block, safety latch, and pendant control. Objective 2
State the frequency that pre-operational inspections should be performed. Objective 3
All cranes SHALL be inspected annually by qualified personnel (ASME B30.16). Pre-operational inspection SHALL be performed by operator at beginning of shift. Move crane to area where block will not hurt anyone or damage equipment if it fails during inspection. Required Inspections
Identify unacceptable conditions that might be discovered during an annual or pre-operational inspections. Objective 4
Check Hooks No more than 5% and not to exceed ¼ inch increase in throat opening. (Dimension A) Measurement taken from punch marks.
No visibly apparent bend or twist from the plane of the unbent hook. No visible cracks. No excessive wear. Safety latch in place. Check Hooks
Check Hoist Ropes Watch for broken wires in this area Check for broken wires
All covers and attachments secure No loose objects lodged on crane or hoist Trolley and bridge alignment correct Check Bridge and Trolley
Cracks Loose bolts Broken or cracked welds End stops properly attached Check Wall-Mounted Attachments
Press STOP button Verify control buttons: Properly labeled Free of damage Verify control cable: Securely attached and not damaged Not putting strain on electrical cable Verify ASME-required warnings in place. Check Pendant Control Warning Label on back or side of control
Move bridge and trolley, looking and listening for signs of defects. Raise and lower hoist. Check cable wrapping on spool. Check operation of limit switches. Check Crane Functions
Check Upper Limit Switches Review Industry Event
Objective 5 Given an unacceptable condition discovered during an annual or pre-operational inspection, state the actions that should be taken.
Move crane to less traveled area. Turn all controllers OFF. De-energize main switch. Place warning signs on crane.. Barricade crane or station watchman. Reporting Deficiencies
Deficiencies must be corrected. Engineering evaluation required if repairing load bearing members. Appropriate tests should be performed after maintenance. Pre-operational inspection shall be done prior to operating crane. Correcting Deficiencies
Identify proper rigging and load handling techniques and restrictions. Objective 6
Crane operator shall perform the pre-plan lift. Use good housekeeping practices. Select and use proper rigging. Preparing for Lift
Check weight capacity of crane and sling. Plan where to set load. Check intended route. Identify potential hazards. Pre-plan the Lift
Ensure adequate clearance to nearby equipment. Ensure aisles clean. Keep tools, cords, and other objects off floor so you can move freely. Use Good Housekeeping
Select proper rigging. Check load tag. Inspect rigging. Inspect sockets, slings, handles, and connections. Remove rigging from service if defective. Select and Inspect Rigging
Describe safe work practices to be used when operating a pendant-controlled crane to lift, move, and set a load. Objective 7
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
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
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
Once sling in place, slowly raise hook to remove slack. Make final inspection. Ensure sling in center of hook. NEVER pull sling from under load while load resting on sling. Raising Hook & Inspecting Load
When heavy loads lifted in critical areas, such as: Fuel pits Reactor building Intake pumping station Special precautions must be taken: Equipment readiness Load movement path In accordance with NUREG 0612. Lifting Heavy Loads
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
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
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
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
If 2 or more cranes used to lift load: One qualified person is in charge: Analyze operation. Instruct all personnel. Positioning. Rigging of load. Movements to be made. If Two Cranes Used to Lift Load NOTE: IF MORE THAN ONE HOOK OR CRANE IS USED, IT IS A HIGH HAZARD LIFT, PERSONNEL SHALL REFER TO SAFETY PROCEDURE ON “REQUIREMENTS FOR SAFE OPERATION OF CRANES” FOR GUIDANCE.
Avoid sudden starts and stops: Causes load to swing. Places extra stress on crane and slings. Maintain smooth steady pace. Slow down gradually. Avoid swinging load. Moving Load
Check intended path Watch for traffic. NEVER carry load over co-workers. Keep both hands firmly on pendant. Face load when traveling. Ensure pendant control wire not tangled with hoist lines. Use tag line if needed to control load. Moving Load
Place bridge and trolley directly over landing position. Do NOT swing load into place. Slowly set load. Lower hook so slings can be removed. Setting Load
State how to properly store a pendant-controlled crane when not in use. Objective 8
Set load. Walk pendant back under bridge. Store all slings; do not drag them. Move crane to designated area. Raise hook to intermediate position. Place controls OFF. Securing Crane
