Breakthrough Earth Anchoring Solutions

MANTA RAY® earth anchors are a driven tipping plate soil anchors for reaction of tensile loads. MANTA RAY anchors have ultimate capacities up to 20 tons. The simple, effective and low cost MANTA RAY anchor system represents a major breakthrough in anchoring technology with a multitude of uses in the Utility, Civil Engineering and Marine Markets.

MANTA RAY offers cost reductions for the installation and repair of walls, sheet piles and seawalls. Many of our customers utilize MANTA RAY anchors to shore-up, stabilize and repair failing walls with superb economic advantages. The bottom line is MANTA RAY is the solution to all your anchoring problems.

MANTA RAY® anchors, a patented labour and time saving device, are driven into the ground with no holes, no digging and no concrete. Unlike other anchoring systems, the MANTA RAY compacts the soil around itself providing a safe and environmentally sensitive installation. The anchors are driven with conventional hydraulic/pneumatic equipment that is readily available worldwide. Once driven to the proper depth, an upward pull on the anchor tendon rotates the MANTA RAY into a perpendicular “anchor lock” position in undisturbed soil. Proper holding capacity is measured by a gauge on the anchor locker. Each anchor is immediately proof loaded to the exact capacity required.

Manta Ray Models for every application

MANTA RAY® offers anchors with light to heavy duty holding capacities. All MANTA RAY® anchors are made of galvanized ductile iron. All anchors are load tested to the desired holding capacity with the anchor locker.

There are seven MANTA RAY® anchors with light to heavy duty holding capacities. MANTA RAY® anchors are made of galvanized ductile iron, are driven with the same drive steel set* and are tested to the desired holding capacity with the anchor locker.
