HULK EARTH ANCHORS

HULK Earth Anchors

Proudly designed and manufactured in Australia, HULK Earth Anchors are backed by more than 27 years of experience in the field of percussion driven tipping plate anchors.

BENEFITS OF THE HULK EARTH ANCHOR SYSTEM
HULK Earth Anchors are driven into the ground, not augered or torqued, saving time and money. They are environment friendly as no digging or excavation is required during installation resulting in no disturbance or displacement of the surrounding soil. As part of the installation process, the anchor is proof tested to the desired capacity and is then ready for immediate use. Hulk earth anchors are an effective solution for meeting superior holding capacity requirements.

HOW DO HULK EARTH ANCHORS WORK?

Installation sequence:

  1. The Hulk earth anchor is driven into the ground to the required depth using a smasher rod, or drive steel.
  2. The re-usable smasher rod is removed from the Hulk anchor leaving the anchor head behind in the ground.
  3. A proof tester is used to pull on the Hulk anchor tendon, rotating the anchor in the ground. This process locks the anchor in place while simultaneously load testing to the desired load rating.

Small hulk earth anchors- sledge hammer is used

Large Anchors- conventional hydraulic and pneumatic percussive, drilling or vibratory equipment which is available worldwide.

THE ANATOMY OF A HULK EARTH ANCHOR

Hulk earth anchors are the result of years of constant testing and analysis of in situ site conditions and present to the market a product designed for the engineer and the installer.

Hulk earth anchors incorporate a number of significant features which improve its overall performance:

Hex Drive Technology

The unique shape of the Hulk earth anchor body allows it to have a slimmer, stronger profile, we call this Hex Drive Technology. This reduces the amount of effort required to drive the anchor into the ground while simultaneously increasing the overall strength. It also provides a wider scoop on the trailing end of the anchor, encouraging it to rotate and lock into position sooner and more reliably during proof testing. Hex drive also allows for clean angles, allowing the product to galvanise well thereby enhancing corrosion resistance.

Widened Scoop

A further benefit of Hex Drive Technology is the wider scoop on the trailing end of the earth anchor which encourages it to rotate and lock into position sooner and more reliability during proof testing. A major benefit of this is that Hulk Earth Anchors pull back less when proof testing compared to competing brands, thereby requiring a shallower installation depth to achieve similar results- a major benefit for production installers.

Chisel Tech

The “cutting edge” technology of the HULK earth anchor. The chisel like leading edge of the HULK provides superior penetration while driving the anchor into the ground, especially in harder ground conditions.

Ball Nose Smasher
The ball nose “Smasher “anchor driving rods offer superior performance and increased resistance to wear and tear. This also reduces the risk of the rod getting stuck in the back of the anchor.

Tendon Attachment

The Hulk Earth Anchor tendon attachment point is built touch for cable, rod or chain. A wide range of tendons are available to cater for any of your anchoring requirements.

Hulk Deflector
The Hulk Deflector protects the anchor tendon from damage while the anchor is being driven into the ground.

Load Max Technology
The reaction surface of Hulk earth anchors is optimised using clever load max technology. Years of experimentation have shown us that surface bearing angles of an anchor have an influence on bearing capacity. Therefore when we coupled the Hex shape of Hulk with the perfect angled wing, frustum cone angles were increased allowing it our Hulks to carry higher loads. We call this LOAD MAX technology. This wing varies in size across the different Hulk models to cater for varying ground conditions.
