Rope Rescue/Equipment/Need/I-beam rigging clamps

From PCSAR

Revision as of 17:11, 19 March 2011

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.
