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

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
  • = 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 MBS is only negligibly greater than the WLL.
