The earth anchors are driven with conventional hydraulic/pneumatic equipment that is readily available worldwide for your power utility project. 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.

- description: The MK-B is the largest of the Manta Ray® anchors and is normally used in the very soft and usually wet Class 7 – 8 soils to accommodate up to 32M* guy capacity. Because of its large size and length, the MK-B exhibits a larger pull–back during load locking than the rest of the Manta Ray anchor family. This pull-back distance can be as much as 7 feet in Class 8 soils. For this reason, the MK-B is routinely not driven any less than 14 feet deep prior to load locking.
