Manta Ray Anchors provide a direct-drive solution for securing structures to the ground, with holding capacities up to 20 tons. These percussion-driven earth anchors combine practical design with proven performance across various soil conditions.
Table of Contents
Manta Ray anchors utilize a one-piece cast design manufactured from galvanized ductile iron. The construction includes a chiseled tooth leading edge that enables successful installation in multiple soil types, from soft to medium-density grounds.
Design Elements
Manta Ray anchors serve multiple industries with specific applications in construction, civil engineering, and marine environments.
Construction Applications
Marine Applications
“Installation and testing of the Manta Ray anchor occur simultaneously, eliminating uncertainty in holding capacity verification”
Understanding load capacity helps select the right Manta Ray anchor model for specific project requirements. Each model provides different holding power based on soil conditions and installation depth.
Model Specifications
| Model | Ultimate Load | Working Load | Typical Applications |
|---|---|---|---|
| MR-1 | 40 kN | 20 kN | Light structures, fencing |
| MR-2 | 89 kN | 44 kN | Retaining walls, pipelines |
| MR-3 | 178 kN | 89 kN | Heavy structures, seawalls |
| MR-4 | 220 kN | 110 kN | Major civil works |
Soil Type Impact Different soil conditions affect anchor performance:
Proper anchor selection requires consideration of several key factors that affect performance and installation.
Selection Criteria
Technical Considerations Each installation requires analysis of:
Manta Ray anchors require specific equipment for proper installation, though the requirements vary by model and application.
Basic Equipment Requirements
Equipment Specifications
“Proper equipment selection ensures efficient installation and reliable anchor performance across all soil conditions”
The Manta Ray system operates through a proven three-step process that allows for immediate verification of holding capacity.
Installation Steps
The system provides simultaneous installation and testing, with each anchor immediately proof-loaded to the exact required capacity using a gauge on the anchor locker.
Manta Ray anchors undergo specific surface treatments to ensure long-term durability. The treatment choice impacts both initial costs and maintenance requirements.
Surface Protection Options
Testing procedures ensure Manta Ray anchors meet project specifications and safety requirements.
Verification Process
Several ground anchor types offer different solutions for various soil conditions and project requirements.
Helical anchors, also known as screw piles, consist of one or more helical-shaped steel plates welded to a central shaft. These foundation systems can be used in both compression and tension applications.
The Bust Expanding Anchor expands to take full advantage of the available hole size, with eight blades that wedge into undisturbed earth.
Disk anchors are corrosion-protected rods with a series of disks attached, positioned in augured holes and filled with grout or soil cutting.
| Anchor Type | Best Soil Conditions | Installation Method |
|---|---|---|
| Manta Ray | Medium-density soils | Direct drive |
| Helical | Various soil types | Rotation |
| Bust Expanding | Rocky/hard ground | Pre-drilled hole |
| Disk | Sandy/loose soils | Direct drive |
What are the load capacities?
Four models are available with different ultimate capacities:
What installation equipment is required?
How deep should anchors be installed?
When load is applied, the anchor typically pulls out 1-2 times the anchor length. Installation depth varies by model and soil conditions[1].
What soil conditions are suitable?
What’s the minimum spacing between anchors?
Minimum 2 feet apart. Spacing varies based on soil conditions – harder soil allows closer placement, softer soil requires greater distance.
How is installation verified?
Each anchor is immediately proof loaded to the exact required capacity using a gauge on the anchor locker. This provides instant verification of holding capacity.
