Bonneville Power needed hold down anchors to support a guide wire at a remote location in Snohomish, WA. Job materials and installation equipment had to be flown to the site via. helicopter. All the equipment was staged on a work platform which the men could work to install and test each anchor. Special care was taken through the project to ensure minimal disturbance to the sensitive wetland area.
McDowell NW Pile King installed 4 each Manta Ray earth anchors model MR-SR, embedded 25’ below grade, 3 ton design load each. Anchors were installed using a 90 pneumatic jack hammer and tested using the Manta Ray load locker system. Anchors were driven to the appropriate depth, tipped into place, load tested and locked off in one easy step using the Manta Ray hydraulic load locker. Manta Ray soil anchors are well suited for use in hard to access areas and sensitive environments.
