Developed and manufactured in Canterbury, New Zealand. This device offers a method to help minimize wind damage.
Background
Pivot Anchors have been developed to provide farmers with a cost effective, quick and simple method of anchoring down irrigators to mitigate the effects of wind damage.
Being able to anchor an irrigator down helps to minimize the oscillating, (bouncing), effect that wind can have on irrigators, which can then cause roll over or significant structural damage. This can result in expensive repair costs and the loss of dry matter production while they are out of action, waiting to be repaired.
Anchor Design
The anchors consist of a steel frame which is held in place with two medium tensile 1045 25mm steel pins that are driven into the ground at a specific angle to a depth of approximately 600mm.
A 9m ratchet tie down connects from this anchor assembly, to a point on the irrigator.
The lateral load gets transferred through the 1045 25mm steel pins into the subsoil resulting in a very robust and strong anchoring method over a range of variable soil types.
Installation
- Install two pivot anchors on the windward side of each span of the pivot. One above the wheels, and the other mid-span.
- Drive the steel pins through the anchor frame using a waratah driver or a sledge hammer.
Installation using waratah driver
We recommend using a Honda powered 4 stroke Waratah driver with internal reducing bush to install the steel pins quickly and efficiently. A sledge hammer can also be used to drive the pins into the ground.
Removal with pry bar
Use a pry bar underneath the anchor frame to remove both the frame and the pins at the same time.
Removal with lifting chains
Lifting chains and a loader will remove the pins if more force is required. Lifting chains are available to purchase on this site.
Warnings
- Check for underground services prior to installation.
- Check pivot anchors are detached before restarting the irrigator.
- Use of pivot anchors is at the purchasers risk.
- Gray Engineering Solutions and Pivot Anchors Ltd will accept no liability for any damage caused to equipment in weather events where pivot anchors have been used.
