1. How Does A Bump Gate Work?

Click here to watch the slide show.

Bump Gates operate by mechanical power and gravity (they do not require electricity or an external power source). There is a rubber-sleeved arm on either side of your Bump Gate. When the gate is gently bumped open, this releases a spring-loaded Lockpin which provides the momentum for your gate to open. When your Bump Gate swings open to about 120 degrees, it strikes a Delay Catch mounted on a small post located either side of the gate. The Delay Catch holds the gate open while you are driving through. After a few seconds the Delay Catch releases the gate and it closes behind you.

When first using a Bump Gate, we recommend that you gently bump your gate with the front of your vehicle and reverse, to observe how far the gate opened and the speed at which to bump it. When the gate has closed completely, repeat this step until you bump the gate sufficiently for the Delay Catch to be activated. When you are confident of the correct amount of ‘bump’, bump the gate and follow it through as it is opening. You do not need to wait for the gate to engage the Delay Catch before starting to drive through.

2. Are They Okay For All Sites?

The ideal site for a Bump Gate is a level site where the gate can swing open 120 degrees in both directions. In addition, there is enough room for the gate to close behind your vehicle if you need to wait for traffic to pass before entering a main road.
Bump Gates can be installed on any property where you can turn a vehicle around safely, as you need to activate a Bump Gate with the front of your vehicle. It is not safe to reverse into a Bump Gate, particularly when entering traffic.

The gate site needs to be clear of objects which may impede the gate swinging open in an arc of 110 – 120 degrees in both directions. (Hold gate at 90 degrees at the lock end and step about 1 m (3’) to check that you have clearance from a fence, trees etc. If not, you may be able to hinge your gate from the opposite post.

If your Bump Gate is at the entrance to your property, you may need to recess your gateway so that when you exit the property, you have room to park in your driveway while the Bump Gate is closing behind your vehicle.
The gate site also needs to be reasonably level. If it is on a steep slope, we recommend that you do earthworks to level the ground 6 metres [20′] either side of the gate to allow your Bump Gate to swing in both directions. This is a much safer option than the dangerous practice of opening and closing gates on slopes. An alternative is to move your gate site to more level ground.

Bump Gates are not for use on public roads where inappropriate use may occur.

3. What Kinds Of Vehicles Can Go Through A Bump Gate?

Bump Gates are versatile and can be opened with 2WDs, 4WDs and light trucks, while on horseback, motorbike, quad bike or on foot. A bull / bush bar is not needed, and the rubber-sleeved arms will not activate airbags or damage vehicles.

Different models of Bump Gate kits have been developed for different vehicles:

  • A standard model is for use with 2WDs
  • A heavy-duty model is for use with 4WDs and light trucks

Bump Gates are not for use by large trucks, road trains, heavy machinery or bulldozers. If you are expecting a large truck or heavy machinery through your Bump Gate, it can be temporarily latched open with the tail of the Delay Catch. (This feature can also be used when moving cattle or for large numbers of visitors).

You can adjust the closing speed of your Bump Gate to suit the length of vehicles going through. (Maximum length is 12 m / 40’). For towing trailers, horse floats, caravans or boats, adjust the Speed Screw inwards and your Bump Gate will close more slowly. Adjusting it outwards will cause the gate to close faster.

If you have a bull / bush-bar fitted, you will need to judge the correct position to bump the arm. Extra care needs to be taken with spotlights and winches fitted to the front of 4WDs.

4. What Type And Size Of Gate Do I Need?

Bump Gate kits fit steel mesh or bar gates that are readily available from rural supply stores. Or you can fit a Bump Gate kit onto a mesh or bar gate that you already have. They cannot be fitted to gate frames made of timber or square/rectangular steel.

In Australia and New Zealand, steel gate frames are made with round steel pipe which is 33mm OD [1 ¼” OD]. (OD is the Outside Diameter of the pipe.) We also supply kits for gate frames made with 42mm OD [1⅝” OD] round pipe for other markets.

Bump Gate kits can be used on gates between 3 to 4.8m (10-16’]) in width, with 3.6 [12’] and 4.2m [14’] being the most commonly used sizes for a Bump Gate.

For towing a trailer or longer vehicles, it is essential to have a gate width of 4.2 or 4.8 m (14 -16’).

A Bump Gate can be used in a double gate system, providing one gate is wide enough for the vehicles you are driving through most of the time (3.6m / 12’ minimum). It may be quicker and easier to replace double gates with a larger single gate.

5. What Type And Size Of Hinge Post Is Best To Use?

200mm (8”) round timber posts are recommended for timber posts but if using steel, we recommend using 100x100mm (4”x4”) minimum. For timber posts, make the opening between your Hinge and Lock post 100mm (4”) greater than the width of the gate to be fitted. For steel posts, the opening needs to be 135mm (5½”) greater than the gate width.

6. Are Bump Gates Easy To Install?

Our simple to install Bump Gate kits are designed for you to install yourself. They require basic skills and tools and take two people 4 to 5 hours to install. If you don’t have time to install the kit yourself, we recommend that you ask your friends or neighbours for the name of a fencing contractor who does quality work, as they will have the skills and tools to install the kits for you.

The Fitting Instructions included in the kits are written in plain English with photos of each step, making them easy to follow. If you or the person installing your Bump Gate has any questions after reading the instructions, or during installation, please contact us on our 1300 number or via email. Calling us before commencing the installation usually saves you time!

7. What’s To Stop Cattle Opening The Gate?

Livestock are prevented from opening a Bump Gate in five ways:

a)  The rubber sleeve on the Bump Rail arms spins around, preventing cattle from gaining a ‘hold’
b)  The Bump arm describes an arc when activated. It does not travel directly in towards the gate
c)  There are three settings to increase the tension on the Cable bracket if the Bump Gate is being installed to contain cattle
d)  Ensure you have the Lockpin a minimum of 25mm (1”) into the Two-way lock
e)  Check that there is some slack in the cable when closed

8. Can They Be Opened By Young Children?

No, they are not strong enough to open a Bump Gate.
