Guy Anchoring

CHANCE® Helical Anchors have been the primary guy wire anchor in electric transmission for decades and are widely used today for guying communication towers, radio towers, poles, and other structures in civil construction.

Field-proven performance with fast, clean installation

Compared to concrete deadmen, helical guy anchors install quickly with no excavation, no spoils, and no cure time. Installation is not affected by weather or high water table and capacity can be verified by installation torque with additional proof testing as needed. CHANCE® Helical Anchors use proprietary high-strength steel and are engineered to resist sustained guy tensions and wind events. Helical anchors can also be removed or extended if the project requires it.

Advantages of CHANCE® Helical Anchors for Guying

  • Quick to install; immediate loading
  • No excavation, no spoils, no concrete or grout
  • Not impacted by high water tables; install from land or water
  • Capacity correlated to installation torque; proof testing available
  • Removable/extendable when specified

MANTA RAY® Earth Anchors for Guying (Percussion-Driven)

MANTA RAY® earth anchors are percussion-driven and then proof-loaded at lock-off to verify capacity on site. They are well-suited for light to moderate guy loads (subject to soil and installation depth), tight-access sites, and rapid mobilization with small equipment. Installation produces no spoils and requires minimal disturbance. Note: MANTA RAY® anchors are not removable.

Advantages of MANTA RAY® for Guying

  • Fast installation with compact tools (jackhammer or small hammer)
  • On-site proof-load verification at lock-off
  • Minimal disturbance; no excavation or spoils
  • Ideal for limited access and rapid response work
  • Not removable

When to Use Each Product

  • CHANCE® Helical Anchors — choose for higher design guy loads, engineered torque-correlated capacity, and when removability or extendability may be required.
  • MANTA RAY® Earth Anchors — choose for light–moderate guy loads, tight access, and fast installs with proof-load lock-off.

Frequently Asked Questions

Are the anchors removable?

CHANCE® Helical Anchors can be removed or extended if the project requires it. MANTA RAY® Earth Anchors are not removable once installed and proof-locked.

How is capacity verified?

Helical anchor capacity is verified through installation torque correlation, with optional proof testing available. MANTA RAY® anchors are proof-loaded at lock-off with a Load Locker to confirm performance on site.

What equipment is required for installation?

Helical anchors are installed rotationally with a drive head mounted on standard equipment. MANTA RAY® anchors are percussion-driven with compact tools (demolition hammer, skid steer hammer, or small excavator hammer).

Which product should I choose for my project?

Helical Anchors are the preferred choice when the project requires stringent testing, engineering sign-off, or detailed design documentation. Their torque-correlated installation provides a verifiable design method and is widely accepted by engineers for critical applications. MANTA RAY® anchors are a practical choice for light to moderate guy loads, limited-access sites, and rapid installations with on-site proof loading.

Your Solution for Other Tiedown Applications

CHANCE® and MANTA RAY® anchors are also widely used where uplift or marine restraint is critical:

  • Anti-Buoyancy — secure tanks, pipelines, and buried structures against uplift
  • Mooring — reliable anchoring for floating docks, barges, and marine structures

CHANCE® Helical Anchors have been utilized over the past five decades as the primary guy wire anchor solution in the electric transmission industry. Today, CHANCE® Helical Anchors are finding increased popularity in civil construction applications for guy wire anchor installations in communication towers, radio towers, and various other structures. 

Field-proven for 200,000 lbs. tensile load

Compared to traditional ways of constructing guy anchorage, CHANCE® Helical Anchors offer a guy anchor design with attractive benefits in the conservation of labor, materials, equipment, and time. Unlike concrete deadmen, CHANCE® Helical Anchor installation is not affected by weather or a high water table, doesn’t require excavation or concrete curing time, and doesn’t produce spoils. CHANCE® Helical Anchors are made with the proprietary CHANCE® High Strength Steel, have capacities up to 200,000 lbs. tensile load, and have been proved in the field under the severest conditions. Using helical anchors in guy wire installation has proved to be the most logical and economical means to resist the maximum tensile load of both the dead load of the tension on the wire and the maximum possible live load due to wind.

Advantages of utilizing CHANCE® Helical Anchors for guy anchoring:

  • Quick to install
  • No time wasted on waiting for concrete to cure
  • Can be proof-tested and loaded immediately
  • Eliminates any need to de-water
  • No excavation or spoils
