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

What are the benefits of the HULK Earth Anchor System?

HULK Earth Anchors are driven into the ground saving time and money. They are environmentally friendly as no 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.

How do HULK Earth Anchors Work?

Hulk Earth Anchors are driven into the ground.

Using Hulk Smasher Rods or drive steels, Hulk earth anchors are driven into the ground. This can be done by hand using a sledge hammer for the smaller anchors, or for the larger anchors with conventional hydraulic and pneumatic percussive, drilling or vibratory equipment which is available worldwide. Once the Hulk earth anchor has been driven into the ground to the required depth, the Smasher driving rod is removed leaving the anchor head behind in the ground.

HULK Earth Anchors are Proof Tested during installation.

Hulk earth anchor install sequence

A Hulk proof tester is used to apply a proof load to the anchor tendon after driving the anchor to the required depth. This load serves two functions:

  • It rotates the Hulk earth anchor in the ground, locking it into position, and
  • It proof tests the Hulk earth anchor to the desired load rating.

Hulk Earth Anchor 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.
  3. Using a proof tester to pull on the Hulk anchor tendon, rotates the anchor in the ground locking it in place while simultaneously load testing the anchor.

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:

Hulk Earth Anchor Anatomy

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.

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.

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.

Common applications for the Hulk H earth anchor range include:

Anchoring of portable buildings or dongas, site offices, containers, and caravans. Anchoring these items securely with Hulk earth anchors prevents them from being washed or blown away during extreme weather such as cyclones and eliminates the need for concrete.

Masts, weather stations, satellite dishes, wind turbines and solar cells can be quickly and easily anchored with Hulk ground anchors.

In agricultural applications Hulk earth anchors are ideal for anchoring trellises, shade nets, irrigation systems and fences.

Due to the quick and cost effective installation of Hulk earth anchors they can be used where permanent or temporary anchoring is required. Hulks are used to secure advertising banners, blimps, signs and inflatables. Hulk anchors are also a popular choice for marquees and tents.

Hulk earth anchors provide the ideal system for anchoring trees. With Hulk root ball kits or Hulk tree guy kits more trees can be anchored in less time, providing a neat and professional appearance.

Hulk earth anchors are used to stabilise structures such as adventure and obstacle courses, and scaffolding.

Geotechnical anchoring applications include soil stabilisation, erosion control, and levee re-enforcement.

Miscellaneous applications included anti-theft anchoring, vehicle recovery, anchoring of playground equipment, anchoring of fixed wing aircraft and much more…

Hulk earth anchors take care of your toughest jobs.
