FALCON ANCHORS - DEEP-SET HIGH-LOAD ANCHORS

Western Excelsior is proud to offer the Falcon Anchor line, providing securing hardware for Turf Reinforcement Mats (TRMs), High Performance TRMS (HPTRMs) and more. Falcon Anchors provide innovative, cost-effective solutions for erosion control and soil stabilization applications. Falcon Anchors are designed to provide immediate stabilization, requires no crimping and are have improved load-locking capabilities, for easy installation. The Falcon Anchors are pre-assembled and are available in different configurations to best meet the specified project requirements and geotechnical conditions. Installing Falcon Anchors offers the performance needed while ensuring considerable time and labor savings.

Anchor assemblies consist of four primary components:

  • ANCHOR

    The anchor is the component driven into the soil that develops resistance to pullout. The size, shape and drive depth effect the pullout resistance of the anchor.

  • TOP TERMINATION

    The top termination grips the ground surface and fabric to secure in place. The size of the load bearing cap effects the ability to hold the soil matrix. Openings in the termination aid in the establishment of vegetation, obscuring and protecting the hardware.

  • TENDON

    The tendon connects the anchor and the top termination. Constructed of high-strength, corrosion resistant galvanized steel or stainless steel, the tendon is a critical piece for long-term performance. The tendon is typically fixed at the anchor side by crimping.

  • GRIP

    The grip is housed in the top termination and secures the tendon in the top termination. A release mechanism can allow for re-setting the assembly, as required.

Each of these components can be varied to provide performance and economy options.

PDAs are driven into the ground, typically a minimum of three feet. Once the tendon is retracted, approximately three to six inches, the anchor rotates into a load-locked position, developing the pullout resistance for the assembly. When the anchor is rotated, the geometry of the anchor creates friction in the form of a frustrum cone. The anchor can resist pullout to the limit of the friction provided by the soil mass surrounding the assembly.

Anchors are available in three sizes. As the size of the anchor increases, working load and ultimate resistance increase:

Falcon F80 Anchor
  • F80
  • Zinc Die Cast
  • Surface Area: 3.4 in²
Falcon F120 Anchor
  • F120
  • Zinc Die Cast
  • Surface Area: 6 in²
Falcon F200 Anchor
  • F170
  • Zinc Die Cast
  • Surface Area: 13 in²

 

Top Terminations are available in 2 sizes. Durability and working load increase with size.

The top termination uses a unique design to allow for optimized working load, while still allowing vegetation establishment. The termination plate is selected based on the anchor size and cabling configuration. The small termination is 4" diameter, while the large termination is 6" diameter.

STEP 1

Insert the drive rod into the Falcon anchor head and place perpendicular to the slope. Insert drive rod with anchor head swiftly through the mat in the desired location.

STEP 2

Drive the Falcon Anchor to the desired depth. Anchors can be driven using sledge hammers, gas powered drivers, or hammer drills.

STEP 3

Remove Drive rod. In soft soils, the drive rod can be removed by hand, in tougher soils the use of a jackjaw may be required.

STEP 4

Load lock the anchor once the rod is removed. Slide the top termination flush to the ground. Place JackJaw baseplate directly over the top termination cap. Ensure the cable is in line with the JackJaw jaws. Handle must be in the up position to open jaws. Move the lever handle in a full down/up motion. Pump until resistance is felt. The top termination cap will appear slightly recessed in the mat once the anchor is appropriately load-locked.
