    Asked on 5/13/2014 by Cristian from La Mirada

    1 answer



      Cristian, the following is what we got from Turtle Plastics;

      Comprehensive Strength
      With the cribbing lying flat, a steel plate was placed along the entire length. An increasing load was applied compressing along the full length of the cribbing. The test was stopped at 50,000 pounds at which the cribbing had deflected only 0.22 inches with slight deformation and no cracking.

      With the cribbing lying flat, a 3-inch steel plate was placed on the cribbing to simulate the contact area of another piece of cribbing. The compression was stopped when there was a deflection of 0.75 inch. The force in pounds averaged 13,350 pounds at which point there was slight deformation and again no cracking. This test was repeated on the solid cribbing where there was a 0.75 inch deflection at 15,780 pounds.

      Stacking Strength
      This test was performed by placing two pieces of cribbing parallel to each other with a third piece on top of and perpendicular to them. The top piece was compressed in the center fo the piece with a 3-inch steel plate. There was a deflection of 1 inch at 2,390 pounds with slight deformation and again no cracking.

      The Conclusion
      There findings demonstrate that Dura Crib is almost twice as strong as the majority of wood currently being used for cribbing. The super stability of Dura Crib increases safety for both emergency personnel and victims.
