Manta Ray Anchor Installation
Drive steel and accessories are available for all Manta Ray anchors in basic lengths of 3 feet, 6 feet, and 8 feet. Multiple sections are coupled together with specialized couplers to achieve the required depth of installation.
Load Locking Kits
For Manta Ray, the LL-1 is a 10-ton fast acting jack with an 8 inch stroke. The direct reading gauge and rod gripping jaws make load locking easy and quick. The base and jack are self-aligning to the actual installed angle of the anchor. It requires an open center hydraulic flow of 2 to 8 gallons per minute and a maximum pressure of 2,000 psi. A power supply is not included with this load-locking kit, it must be provided separately. Models GPU18-8 or GPU-2 are suitable.
Vehicle Mounted Breakers or Compactors:
Boom mounted demolitions or compactions are very effective for driving Manta Ray anchors. This method requires a special tool in the breaker or a socket welded to the bottom of the compactor to hold the drive steel. Skid steer loaders, backhoes or excavators work well. 4,000 to 16,000 lb. Vehicles with 250 to 500 foot-pound pavement breakers are best for Manta Rays. Breaker tools and vibro sockets are available upon request.
Top hammer or down-the-hole hammer rock drills are very effective for installation of Manta Ray anchors. For hard soil or weak rock installations, the drill can be used to drill a pilot hole. Williams can provide striker bar adapters for these types of drills. Rock drilling steel can also be modified to drive Manta Rays.
In some applications, Manta Ray anchors are driven into the soil with a 90 lb. pavement breaker and coupled drive steel. Pneumatic or hydraulic breakers are acceptable, but a 90 lb. weight class breaker is necessary.
