Need

I-beam rigging clamps

  • for training at Fire Hall
    • sloped I-beams, flange 4 inches wide
      • need to determine flange thickness
      • determine slope angle
    • horizontal I-beams, flange approx 7-8 inches wide
      • need to determine flange thickness
      • more accurately measure flange width

Requirements

  • adjustable from 4 to 8 inches
  • placeable on sloping I-beam
    • non-rolling
  • MBS: 40 kN
    • 2 person load, SSSF, pulley at top
    • = 8993 lbf
    • WLL is not the same as MBS. It has a Design Factor (DF) built in for safety. That factor is not documented; OSHA talks about factor 2 in other parts of its standard. But without specification, we assume that the WLL is only negligibly less than MBS.
