Spot shoring test

Testing of Trench Rescue spot shoring. Paratech struts with 18" rails were placed at 2' depth and 6' depth at a 4' horizontal spacing. A 4' deep trench was cut behind the trench and airbags were used to pressure the earth and the shoring system. The airbags were inflated to their limits. Load cells on the top struts recorded the loads carried by the struts.
