Manta ray earth anchors and Stingray earth anchors are driven tipping plate soil anchors dependant on soil strenght for reaction of tensile loads. Manta ray earth anchors have working loads up to 20 kips, and Stingray anchors have working loads up to 50 kips. After driving the anchor to the required depth, the driving tool (called drive steel) is removed. The anchor is then tipped and proof tested with Williams Anchor Locking Kit from its edgewise-driving position to present its bearing area to the soil. This is called "load locking" and provides an immediate proof test of each anchor.
Manta ray earth anchors and Stingray anchors offer many significant advantages:
• Fast, easy installation
• Immediate proof test results
• No grout
• Inexpensive installation equipment
• Environmentally friendly
• No drilling required
• Superior Holding Capacity
• Anchors for a wide range of soils & applications
The simple, effective and low cost Manta ray earth anchors and Stingray anchor system represents a major breakthrough in "anchoring technology" with a multitude of uses in the utility, civil engineering and construction markets for:
• Utility Poles
• Retaining Walls
• Sheet Piles
• Seawalls
• Pipelines
• Erosion Control
• Underwater Applications
• Blockwalls
• Scaffolding
