[edit] Need

I-beam rigging clamps

  • for training at Fire Hall
    • sloped I-beams, flange 4 inches wide
      • need to determine flange thickness
      • exterior roof has 12 degrees slope; interior ceiling has 2 angles: the edges are greater, the center less (where we will be working)
    • horizontal I-beams, flange approx 7-8 inches wide
      • need to determine flange thickness
      • more accurately measure flange width

[edit] Requirements

  • adjustable from 4 to 8 inches
  • placeable on sloping I-beam up to 12 degree slope
    • non-rolling
  • MBS: 40 kN
    • 2 person load, SSSF, pulley at top
