Say goodbye to blasting. And say hello to our inclined modular
Tri-Anchor design.
More than 60,000 poles installed and counting.
In the late 1970's, we suggested something unheard of to North American utilities: Put away the dynamite. And install more poles per day by anchoring them on rock, rather than spending precious time and money blasting the rock away.
The message got through. Today, there are more than 60,000 poles installed on rock with the Tri-Anchor
® system throughout North America. And we've yet to hear of a single failure.SAFE: Eliminates the risks and environmental hazards inherent in blasting.
MORE PRODUCTIVE: Install more poles per day. Work in almost any kind of weather. Keep tighter control of scheduling and costs.
PROVEN: Thousands of poles installed with zero failures.
EASY TO USE: Simple installation needs only a two-man crew.
New inclined modular design: A superior design gets even better.
Now there are more reasons than ever to switch to the Tri-Anchor
® system. Reasons like greater strength, simplified inventory, easier installation, and greater value. All made possible by the modular design of our new Inclined Universal Tri-Anchor® system. That means instead of purchasing and stocking different sizes for different pole diameters, all you need is our inclined Universal model. One size fits all. And you gain all of the following:MORE STRENGTH: inclined design creates a conical assembly, resulting in 48% to 85% improvement in ground line moment capacity.
SIMPLIFIED INVENTORY: Universal design- one size fits all diameters. Sold in bulk.
STANDARDIZED SIZE: Simplified tool and drill requirements.
GREATER VALUE: Significantly more strength at no additional cost.
| A 20" diameter pole on the test bed. Ground line moment is 121,275 ft. lbs. at 6.5 degree rotation. Installation shown uses five inclined Universal Tri-Anchor modules, each requiring the standard two inch diameter holes drilled to a depth of 24". |

INCLINED UNIVERSAL TRI-ANCHOR MODEL No.9 The new modular Tri-Anchor for distribution poles comes in just one size, which can be used in various configurations. To choose whether to use 3, 4,or 5 anchor modules on any given pole, consult the following table for the appropriate pole butt diameter and your required ground line moment. |
