Manta Ray earth anchors are mechanical anchors driven into the ground with conventional hydraulic/pneumatic equipment. Once driven to the proper depth, remove the drive steel, an upward pull upon the anchor rod to rotate the anchor into a perpendicular “anchor lock“ position in undisturbed soil – like a toggle bolt in soil. The anchor is pulled to reach the holding capacity required which is measure by a gauge on the anchor locker. Each anchor is immediately load tested to the exact capacity required.
