Two (2) Hydratight technicians were at a customer’s facility performing a tensioning job using a HM- 13, 3” Hydramax on a Delta Clamp with 4-3" custom studs. During tensioning operations, one of the studs yielded as a result of a tension failure at the clamp, causing the tensioner to lift above the clamp (see photo 1&2).
