MANTA RAY PERFORMANCE Revolutionizes Anchoring Technology MANTA RAYs are driven into the ground, not augured or torqued, nor is a hole dug or drilled. There is "no disturbance" or "displacement" of soil. Unlike other anchoring systems, MANTA RAY actually compacts the soil around itself - a clean, safe and simple operation. The anchors are driven with conventional hydraulic/pneumatic equipment that is readily available worldwide. Once driven to the proper depth, the rod/tendon attached to the anchor is pulled to rotate the anchor into undisturbed soil - like a toggle bolt. This is called "ANCHOR LOCKING" the anchor (using the MANTA RAY Anchor Locker). The anchor is pulled upon to reach the holding capacity required which is measured by a gauge on the "ANCHOR LOCKER." Each anchor is immediately proof loaded to the exact capacity required. No other system offers this feature.

Stingray earth anchors are driven tipping plate soil anchors for reaction of tensile loads. Stingray anchors have ultimate capacities up to 50 tons. After driving the anchor to the required depth, the driving tool (called drive steel) is removed. The anchor is then tipped and proof tested with JLD's Anchor Locking Kit from its edgewisedriving position to present its bearing area to the soil. This is called “load locking”, and provides an immediate proof test of each anchor.
