|
MANTA RAY RANGE: |
|
There are six MANTA RAY anchors with light to super heavy duty holding
capacities. |
|
All MANTA RAY anchors are made of galvanized ductile iron, can be driven with
the drive steel set (except the MR-88), and can be tested to the desired holding
capacity with the anchor locker. |

|
2. Installation: |
|
Manta Ray Installation: |
1. Anchor rod is screwed into the threaded shackle of the anchor and the first
section(radius drive tip Of the drive steel set is
inserted into the anchor. |
|
2. One man at ground level using a standard jack hammer drives the MANTA RAY
into the soil at the desired angle and depth. |
|
3. Anchor locker base and hydraulic ram system are placed over adapter setting
bar |
4. Power source operates the anchor locker, gripping the adapter setting bar,
rotating the anchor underground into its locked
position, proof loading anchor
to the holding capacity required. |
|
5. Installer pulls the drive steel out of the ground and screws adapter setting
onto the end of the anchor rod. |
6. Anchor locker is removed, thimble eye is screwed onto the anchor rod ready
for guying. No digging, no damage, no mess. A
clean, simple and safe operation. |

MAD- Manta Ray Anchor Driver:
The MANTA RAY Anchor Driver can be installed on a wide range of commonly
available construction vehicles; from medium skid steers to large excavators can
be installed using small vehicles or even hand held equipment. |
|
|
|
|
The MANTA RAY Anchor Driver was developed by Rope Constructions for large scale
projects including 360 degree horizontal and vertical applications requiring
high-speed, efficient and repetitive anchor installations. |
|
|

|
Revetment Mats:
MANTA RAY anchors provide critical points of anchoring stability on stream and
shorelines to prevent water erosion using cellular concrete revetment
matting. The anchors install easily through openings in individual blocks. This
system prevents lifting of mats and dangerous erosion under extreme flood
conditions. |
 |
|
Gaboins:
The flexibility of the MANTA RAY system allows gaboins to be installed on steep
slopes. The ease and speed of the installation provides a cost-effective
alternative to traditional anchoring methods. MANTA RAY anchors also stabalize
embankments that are in need of repair and facilitate slope stabilization by
securing geogrids, geotextiles and fiber mats |

|
Sheet Pile:
Civil engineers for this project chose MANTA RAY earth anchors to provide
overturning stability for the sheet piling rather that structural piles driven
into the bedrock. Cost saving were substantial. |
 |
|
Blockwalls:
MANTA RAY tie backs allow minimum excavation for mechanically stabilized earth
walls. This allows BLOCK/GEOGRID walls to be installed where excavation is not
possible. |
 |
|
Timber Walls:
Rather than conventional timber deadmen, MANTA RAY anchors are used to provide
proof loaded tie backs to insure permanent structural integrity with minimal
excavation. |
 |
|
Concrete Walls:
New installation and resoration of concrete and stone walls have proven the
MANTA RAY's versatility and money-saving attributes worldwide. |
 |
|
Internal Waler:
Best system for walls designed for anchors. Internal steel waler also can
accommodate grid attachment. |
|
|
|
|
3. Pipeline Control |
 |
|
Pipeline Control:
The compact and portable installation equipment allow MANTA RAY to be installed
in locations normally inaccessible to traditional earth anchor methods. |

|
Relocatable Structures - Cover All:
As a specified supplier to the US Military, MANTA RAY are specified to anchor
rapid deployment relocatable structures. |

Dock & Moorings:
From the Great Barrier Reef to the Red Sea, MANTA RAYS are used to anchor
moorings that help protect coral reefs and other natural resources. Now There is
a enviromentally friendly anchor system that installs easily underwater with
conventional equipment for buoys, floating docks, man made reefs and more. |
 |
|
Historic Restorations:
MANTA RAYS are used in the resoration of buildings, monuments and structures in
order to maintain their historic integrity. |
 |
|
Scaffoldings:
MANTA RAYS are used to secure and support scaffolding for building projects
worldwide. |

5. Locker |
 |
Hydraulic Powered Anchor Locker:
The distinct advantage of the Manta Ray System - Installation and testing are
simultaneous. |
 |
Manufactured from high grade metals, sections of the drive steel are coupled
together so that the driving operation can be accomplished safely from ground
level. |
 |
Anchor locker pulls up on the anchor to set it in the ground at the desired
holding capacity. Portable and lightweight, the anchor locker consists of a base
plate and hydraulic ram. |
|
|
|
|
Desired holding capacity is measured by the gauge on the anchor locker. NO MORE
