Safety Chain Attachment Statement 2024

By Useful Information

Compliance with ADR 62/02

The Australian Design Rule 62/02 – Mechanical Connections Between Vehicles (ADR 62/02) provides comprehensive guidelines for safety chain attachment points on trailers. At Stonegate Industries, we ensure that our safety chains and attachment method not only align with these requirements but also surpass the benchmarks set by the Australian Design Rules (ADR) for vehicle safety, particularly for trailers with an Aggregate Trailer Mass (ATM) up to 3.5 tonnes.

As per ADR 62/02, safety chains must be affixed to a substantial structural member on every trailer, furthermore safety chains must comply with AS 4177.4 – 2004, which outlines safety chains up to 3500 kg capacity. Each safety chain must withstand specific static forces without incurring any residual deformation or separation of components, ensuring the integrity and safety of the connection.

Our Attachment Method

Our safety chain attachment method complies with ADR 62/02, it involves the first link of the chain being welded directly to the drawbar. This technique is not only efficient but also robust, providing a secure and durable connection crucial for safety. The welding process is carried out with detailed instructions and under strict quality control measures to ensure consistency and reliability in every trailer we produce. Our safety chain attachment method is also tested by an accredited, registered testing facility, ensuring it can withstand the operational stresses defined in the ADR 62/02.

Rigorous Testing and Verification

To validate our commitment to safety and compliance, we have our safety chains (both galvanised and uncoated) rigorously tested by an RVSA-approved testing facility. This facility conducts an array of tests to evaluate the strength and durability of our safety chains, ensuring they can withstand the operational stresses defined in the ADR 62/02 and AS 4177.4 – 2004. The positive results from these tests are a testament to our commitment to maintaining the highest standards.

At Stonegate Industries, we understand that our customers rely on us not only for quality products but also for peace of mind that comes from knowing they are compliant with national safety standards. Our adherence to ADR 62/02 in our safety chains and attachment method is a prime example of this commitment. By rigorously testing and verifying our processes, we ensure that every trailer that leaves our facility meets the highest standards of safety and compliance.

We hope this insight into our processes reaffirms your trust in Stonegate Industries as a leader in trailer manufacturing. Safety and compliance are not just regulatory requirements for us; they are integral to our ethos and our promise to you, our valued customers.

Stay safe and compliant with Stonegate Industries.

Wheel Bearing Maintenance

By Useful Information

Essential Wheel Bearing Maintenance for All Types of Trailers

Did you know that wheel bearing failure is a leading cause of incidents for all types of trailers? Wheel bearings are critical components that are both cost-effective and straightforward to maintain, which is essential for the longevity and safety of your trailer.

Regular servicing and replacement of wheel bearings by your nearest Stonegate Trailers provider, as per our recommended service intervals, is highly advised. However, it’s also vital to conduct your own checks in between professional inspections.

Here are some easy steps for a basic wheel bearing examination:

  1. Securely position and lift one side of your trailer so that the wheels can rotate freely.
  2. Manually spin the wheel at a consistent speed and then let it coast. Listen for any abnormal sounds such as grinding, clicking, or rumbling. These noises might indicate that the bearings need professional servicing or replacement.
  3. Hold the wheel at its extremities and gently rock it without rotating. Any noticeable play might suggest that your bearings require adjustment or replacement. Contact your Stonegate Trailers dealer or arrange for a bearing check-up.
  4. Remove the grease cap or bearing buddy to inspect the grease condition. If you observe contamination or rust, it’s time to get in touch with your dealer for a bearing service.
  5. Grease appearing on the inside of the rims is a significant indicator that the seals might need replacement.

Remember, proper maintenance of wheel bearings is key to ensuring the safe and smooth operation of any trailer.

What is galvanising

By Useful Information

Here we explain in detail what “galvanising” really means, why it’s important and how to best care for it

Think of galvanising as a superhero coating for steel, protecting it from corrosion. It sounds simple, but there’s a bit of magic in it. This protective layer is made of softer metals (mainly zinc), and the team needed a metal that would corrode so that the steel underneath didn’t have to corrode. This special coating is applied in galvanising plants using an exotic process called electroplating.

It’s all about appearance

The galvanised finish is truly a chameleon! They may look different depending on several factors, such as how long they were left in the zinc bath or the temperature used. Some finishes are shiny, some are dull, and sometimes the surface can even appear wavy due to the hot galvanising process. But hey, it’s all good! Our formula ensures you get a tough finish, embracing these variations as part of its unique character.

Corrosion – not as scary as it sounds

Galvanic corrosion may sound like a complicated term, but it’s very simple. This occurs when dissimilar metals come together and have a conductor around them. It’s like an electronic party where one of the metals eventually wears out. A common example is the sacrificial anode in an outboard – it’s the life of the party and corrodes away to save the rest of the engine.

Invisible shield for your trailer

The trailer’s zinc plating acts like its own sacrificial anode. When exposed to moisture, whether from rain or ocean waves, it slowly dissolves, protecting your steel frame. Depending on where you take your trailer, this suit can last for a short time or a long time.

Tips for keeping your trailer happy

Here are some tips for making your trailer last longer: Keep your trailer clean, store it in a cool, ventilated area, and touch up any scratches with anti-corrosion paint. Show your trailer some love regularly and it will pay you back for years to come.

Embrace change

As your trailer ages, its surface will change, and this is completely normal. This is just a sign that the coating is doing its job. Parts rusty? Replace them early to prevent rust.

What not to do

Steer clear of acidic cleaners or harsh chemicals – they are no friend to your trailer’s galvanised surface.

Expect the best

We’re very proud of our trailers and we think you’ll love them too. Take good care of your trailer and it will become your reliable road companion for a long time to come.
