Helical Piles, Helical Anchors & Helix Anchors Chance typical specification ecp helical torque anchor

Helical plates are spaced at distances far enough apart that they function independently as individual bearing elements; consequently, the capacity of a particular helix on a helical anchor pile shaft is not influenced by the helix above or below it. For more than 100 years, CHANCE helical piles have been the helical of choice.Helical Torque Anchors Design ExamplesThe specified Torque Anchorassembly will consist of the following TAF -2884 01 12 Th is a 7 8 diameter tubular product, having a standard len g tho f7 e on, wi an 8,a 10,and a12 d im e ter pl s hat r 3 8 ck, T E 28Exten sion, wh ch 7 feet long and in c lu des oup ng ha rwa e.Helical Torque Anchors Earth Contact ProductsHELICAL TORQUE ANCHOR.
