    • Trolley-Suspended

    • Overhead powered

      • Single reeving

      • Double reeving

        Safety

        overloading

        Limit Switches


Principles and practices

Principles and Practices

  • General Practices

    • Properly Trained

    • Rigger familiar with equipment

    • Rigger makes final say on safety

    • If signaling requires only 1 person in charge

      • Everyone as say to stop

    • Before moving determine where it is going

    • Load is free to move, not fastened to ground

    • Be sure everyone is clear of area

    • No shock loading

    • No riding

    • Do not move over where people are working

    • Never Leave suspended

    • Never work under load unless provisions to support are in place

    • Keep hands fingers out of the way


Principles and practices1

Principles and Practices

  • Sling Operating Practices

    • Avoid sharp sling angles

    • Do not pull sling from under a load when load is resting on sling

    • Do not leave slings on the ground

    • Slings should be stored properly

    • Repair or remove damaged slings

    • Do not hammer metal mesh slings


Principles and practices2

Principles and Practices

  • Turning a Load

    • Most difficult maneuver

    • Consider all options before moving

    • Determine center of gravity

    • Will blocks be required to support load

      • Can use

        • One-hook turn

        • Single-Sling Turn

        • Two-Hook turn

        • P.89


Principles and practices3

Principles and Practices

  • Eye Bolts

    • Have pull ratings and must be remembered p.92

    • Rigging thought Process

      • What is done with load

      • What tools are needed

      • Is capacity enough and adequate

      • How can the hook up be

      • What will happen with path of travel

      • What will happen once load is lifted

      • How will load be stored


Scaffolds and ladders
