The Building of a Spitfire Aluminium Trailer

 

 

 

Designed for Life... Built for Life

 

 

 

 

3D Imagery Designs & Certified to Australian Standards

 

Each Spitfire trailer chassis and draw bar begins with a design, approved by an Australian Engineer to exceed the stated ATM  by a factor of 5 which qualifies for off road use. Design are made in 3D imagery. This allows all parts and moving components to be checked for correct and free travel.

 

 

   

Aluminum Extrusion for Spitfire Trailer Chassis

 

Production begins "In House" from massive billets of aluminium. The correct die is installed into the extrusion machine... in this case an I-Beam  die.

 

 

 

The metal flows....  and a Spitfire I - Beam is formed.

 

 

Marine/Aircraft Grade

6061-T6 Aluminum Alloy

 

  1. High strength
  2. Light weight
  3. Heat-treatable, and is easy to weld, cut,

form and machine. 

 

 

 

 

 

 

The same process applies to Spitfire Cross members and Draw Bars. All are formed 'in house' and 'worked on' while the metal is in it's 'soft mill finish' state.

 

 

 

Let us explain why this term ...'worked on' .... is so very important.

 

Aluminium needs to go through several processes to be finally ready for it's intended use. These are generally extrusion, brushing or sand blasting, hardening and anodising. Many aluminium trailers are made from hardened aluminium, that is hardened chassis rails or cross members are bent to shape. This process is detrimental to objectivity and can lead to cracking and structural failure.

 

The correct process of bending before hardening results in a natural shape allowing the crystallized structure of the metal to retain it's memory resulting in a metal that is almost as strong, or in some cases stronger than mild steel.

 

Anodising, apart from protecting the look, resale value and life of the trailer provides a protection against galvanic reaction (corrosion) and so anodising after fabrication protects the inside of any holes and even the welds.

 

 

High Precision Fabrication

 

Bending - Drilling - Punching - Welding

 


 

Bending, drilling, welding or punching are performed while the metal is in it's 'raw mill finish' state. 

 

 

Hardening & Anodising after Fabrication

 

In order to maintain maximum structural integretity of the metal, the parts are then hardened and anodising after fabrication. This process ensures that the anodised protection is total. It covers the welds and even inside the holes. Hardening the metal after bending and welding ensures maximum strength.

 

 

The quality of the anodised finish is truly beautiful to see, touch and feel... and will give lasting protection against corrosion and certainly retain resale value.

 

 

Quality Control

 

Quality Control checks are ongoing and range from checking metal hardness, anodise thickness to salt water corrosion resistance. 

 

QC Metal Hardeness                            QC  Anodise Thickness                       Corrossion Resistance Test

 

The Industry standard for commercial anodising is 8 microns and Spitfire Trailers usually give a reading of between 10 to 17. 

 

 

 

 

 

 

 72 Testing Hours = 6 Years of Regular Use 

 

One hour in this pressure chamber is equal to one month in a natural environment... so a 72 hour heated salt pressure test is equivalent to  6 years of use in a natural environment.

 

 

 

 

 

 

 

 

 

Identify Inferior Quality  =  Maintain Higher Quality

 

Component samples, including those purchased outside are continually tested in a Salt Water Pressure Chamber where salt water is heated to 45 degrees Celsius and sprayed under pressure for 72 hours to identify inferior quality and mantian higher quality of outsourcing. 

 

 

 

 

 

 

 

 

 

More Materials for Customer's Selection

 

 

 

 

Stainless Steel

 

With the exception of nuts and some bolts, all Stainless steel components are  "Fabricated in House" as are all aluminium parts.

 

 

 

Welds are electrically cleaned and pacified against corrosion.

 

 

 

 

Now assembly can begin.

 

 

 

 

 

DESIGNED FOR LIFE..... BUILT FOR LIFE

 

 

The Spitfire Design Team and management have one clear direction.. and that is Design for life and Build for life.

 

Certification of the chassis and draw bars is only part of this objective. From the coupling to the tail lights,  we at Spitfire Aluminium Trailers strive to acquire the highest quality outsourced components for all our Trailers.

 

In all cases all parts, be they tyres, rims or lights comply with relevent government acts or legislation.

 

 

 

'AL-KO' / Cast Override Couplings 

 

  

 

Couplings, be it an unbraked 'AL-KO' coupling which we use on our unbraked trailers or a cast override coupling on our braked trailers you will always see it clearly stamped in accordance with the regulations.

 

 

 

 

 

Decromat Hand Winch 

 

Spitfire Winches are made from Cast gears and  are Deromet finished.

 

Sizes are available from 300kg, 700kg, 1000kg and 1500kg and differ depending on trailer size.  

 

                            

 

 

 

 

 

 

Draw Bars 

 

 

Draw Bars are all Aluminium box sections and certified by an engineer.

 

 

What is a factor of 5 X... ?

 

Under the Australia act and regulations of VSB 1 and it's Amendments, a  Chassis must resist stresses 3 times the ATM.

 

Meaning a trailer with an ATM of 2,000kg can actually withstand the stress of  6,000kg. This is the requirement for on road use.

 

The factor of 5 X is for off road use and equates to 10,000 kg stress on a trailer with an ATM 2,000kg.

 

Most of the Spitfire Range of Models are built to factor 5X.

 

 

 

All Spitfire Aluminium Trailers are designed and certified by Australian engineers.

 

 

  

 

Whether you are looking for a small boat trailer, a box trailer, a multi transporter or a heavy duty braked boat trailer you will appreciate

the dedication and commitment which ensures the qualitty of Spitfire Aluminium Trailers.

 

 

 

Spitfire Brake System = Safety & Reliability

 

  

 

Long gone are spring suspensions and mechanical cable brakes.

 

Spitfire's standard accessories include a Deemaxx hydraulic brake system and ALKO torsion axles for a safe, smooth ride and long term reliability

 

 

 

 

 

ABS Mudguards & Aluminum Rims

 

 

Mudguards are made from ABS for long lasting crack resistant service.

 

Rims are naturally Aluminium Alloy for higher standard and better corrosion resistance.

 

 

 

 

 

 

 

 

 Spitfire Special Design - Easy Loader System

 

Spitfire Easy Loader offers the strongest chassis with an easy loader system. 

 

Innovation and a determination to not compromise strength by following industry standards, have seen Spitfire develope a simple Easy Loader which still offers the benefits of drive on loading of a boat, yet also retains a straight and fixed rear cross member giving maximum chassis strength and stability.

 

So strong is this design, that Spitfire Aluminium Trailers with the Spitfire 'Easy Loader' can still be Certified to a Factor of 5 X for off road use and offer the boat owner  an entry loading system that protects the hull from contact with any metal on the trailer. (this after market product comes as an additional cost)

 

Basically, if you can guide your boat to enter between the tail lights you have scratch free entry.

 

Spitfire Easy loaders are also offered as an after market accessory to all trailer owners no mater what make or brand and are available in all trailer sizes.

 

They are easily fitted to all boat trailers (at an additional cost) and can be acquired from any Spitfire authorised outlet.

 

 

 

 

 Multifuntional LED Tail Lights 

 

Tail lights are important to be reliable to protect you valuable cargo but also need to be practical.

 

Each Spitfire Trailer is fitted with twin tail lights, which include twin down lights.... down lights allow you to see the road around your vehicle in your side mirrors while driving, invaluable to the experienced driver.

 

In addition Spitfire managment and designers are experienced in boating..... we know how difficult it can be to back your boat and trailer into your parking spot after a long day on the water...so Spitfire tail lights are designed with twin powerful reversing lights.

 

 

 

 

 

 

Spitfire Aluminium Trailer = Your Best Choice

 

Why Aluminium.... Why Spitfire... Why is the pricing similar to galvanised steel trailers ?

 

Price

When you compare a Spitfire Aluminium Trailer to the industry standard galvanised steel trailer, you will find in many cases our pricing is similar, before considering that our trailers include AL-KO torsion axles, Deemaxx hydraulic brakes (on all trailers with an ATM over 750kg), Alloy wheels and all boat trailers over 5.8 metres come with a walk way.

 

Consider the benefits of aluminium - rust resistance, last longer, higher resale value and less trailer weight, so you may find that when using a Spitfire Aluminium Trailer you are below the limit for a braking system.

 

 

Resale Value

Most trailer boats outlast their steel trailer by 2/3 lifetimes, so the trailer is an important part of your boat, motor / engine package, not only for offering you reliability when traveling but also for maintaining resale value.

 

We believe that Spitfire anodised aluminium trailers are the most stylish, strongest and durable trailers on the market.
