The Manta Ray Anchor is a driven earth anchor system that resists tensile loads in tiebacks, seawalls, solar panels, and other anchoring applications. Driven into the ground without excavation, it works across various soil conditions including caliche, decomposed rock, glacial till, and permafrost. Construction from ductile iron with hot-dip galvanized finish provides corrosion resistance and durability, while a chisel-tipped nose penetrates dense or cobbled soils effectively.
Installation uses a hydraulic or pneumatic jackhammer to drive the anchor to depth, with no auguring or torquing required. Once driven, the drive steel retracts and an upward pull on the anchor rod rotates the head to lock it in undisturbed soil. Each anchor is proof loaded using a hydraulic load locker to verify holding capacity on-site, ensuring performance standards are met before final lock-off.
Models include the MR-1, MR-2, MR-3, and MR-SR, with ultimate load ratings from 16,000 to 40,000 pounds and weights from approximately 7 to 21 pounds. Anchor rods accommodate sizes from 5/8 inch to 1 inch, with typical installation depths of 6 to 30 feet. The system eliminates digging, concrete, and cure time, reducing installation costs while compacting soil for stable, environmentally sensitive placement in utility, civil engineering, and marine applications.
Rugged Manta Ray Anchor from RaxPower – Your Go-To Supplier
Manta Ray Anchors are RUS approved, rugged and versatile driven plate anchors for all types of soil conditions. RaxPower, established in 2003 and located in Hebei Province, China, is a leading manufacturer with over 21 years of experience in pole line hardware.
Utilizing 30,000 square meters of production workshops and advanced processes like hot forging, we ensure these anchors are manufactured for maximum strength, accuracy, and durability. They can be installed in extremely tough soils such as caliche, decomposed rock, glacial till, and permafrost. Installation is achieved by driving them into the ground with a jackhammer, not augured or torqued, with no excavation necessary. Fully portable equipment that fits in the back of a standard pickup truck enables access to difficult locations, or installation using a line truck’s hydraulic system.
Every anchor is proof tested during standard installation procedures for a verified tension load measurement, supported by our rigorous load testing and multi-stage quality control, including hot-dip galvanizing per ISO standards. Manta Ray anchors are compatible with standard power hub anchor rods and eyenuts for distribution guy anchors.

Frequently Asked Questions
Why should I choose Manta Ray anchors over concrete deadmen?
Unlike concrete deadmen, Manta Ray anchors require no excavation, no spoils, and no cure time. They install with compact tools, perform across soil types, and deliver instant, verifiable results, reducing labor and cleanup costs.
In what applications are Manta Ray anchors commonly used?
Manta Ray anchors are used for tiebacks, seawalls, fabric structures, solar panels, utility guy anchoring, pipeline anti-buoyancy, foundation stabilization, erosion control, and marine applications such as docks and bulkheads.
How is the holding capacity of each anchor verified to ensure reliability for critical infrastructure projects?
Every anchor is proof tested during standard installation using a Load Locker, providing immediate on-site verification of the tension load measurement. This ensures each unit meets required safety standards before use, essential for applications like grid maintenance or railway electrification where extreme reliability is paramount.
What makes the installation process more efficient and cost-effective compared to traditional methods?
The anchors are driven into the ground with no excavation needed, using conventional hydraulic equipment that is readily available. This eliminates spoils, concrete, and cure time, significantly reducing labor costs and installation time—ideal for projects requiring rapid deployment, such as renewable energy sites or bulk orders for EPC contractors.
What soil conditions are suitable for Manta Ray anchors?
Manta Ray anchors are versatile for all types of soil conditions, including extremely tough soils like caliche, decomposed rock, glacial till, permafrost, and swamps. They compact the soil around themselves for stable installation.
What equipment is required to install Manta Ray anchors?
Installation requires conventional hydraulic equipment such as a jackhammer or handheld hydraulic tools. Portable equipment fits in a standard pickup truck, and accessories like drive steel and a load locker are used for driving and proof testing.
What are the available models and their load ratings?
Models include MR-1, MR-2, MR-3, and MR-SR with ultimate load ratings from 16,000 to 40,000 lbs. They accept anchor rods from 5/8″ to 1″ and are made of hot-dip galvanized ductile iron for durability.
Are Manta Ray anchors removable after installation?
No. Once driven and proof-locked, Manta Ray anchors are not removable. If removability is required, consider helical anchors instead.
How does the anchor design ensure long-term durability in corrosive or harsh environments?
Our anchors are constructed from hot-dip galvanized ductile iron, which provides superior corrosion resistance. This design withstands challenging conditions like marine sites, industrial areas, or variable soils, ensuring reliable performance over time—critical for telecommunications, utilities, and railway applications where hardware must endure constant exposure.
Can you support bulk orders with reliable delivery timelines for large-scale projects?
Yes, we are equipped to handle large orders with committed delivery times, though large quantities may be shipped in multiple shipments to ensure timely fulfillment. Our efficient manufacturing processes, including automated machines and strict quality control, help maintain consistent production rates to meet project schedules for distributors, importers, and EPC contractors.
