Streess Tests

INDEPENDENT CERTIFICATION - FOR THE PROTECTION OF ALL.


Independent Certification by Australian Vehicle Engineers


Stress Tests by independent engineers are carried out to ensure the design exceeds the requirements for the capacity.


Every Spitfire Trailer design is submitted to Independent Vehicle Engineering companies  for Structural Certification for on road use before going into production.


The measure of a trailer meeting design or specified legal requirements is basically controlled by 3 factors.

1.

The chassis and frame must be designed for the ATM.

2.

The wheels, tyres and suspension must meet the designed or required ATM.

3. 

The Coupling must meet the designed or required ATM.

So trailers are usually  manufactured in the following category groups:

Unbraked;

400kg, 600kg and up to 750 kg are un-braked and for these Spitfire Trailers  use our certified 75mm - H Beam design.

H Beam Chassis

All trailers above 750kg need  brakes.


Braked Categories;

1,120kg

1,500kg 

1,850kg

2,000kg

2,500kg

3,000kg  

3,500kg


Important;

  • For all the above braked categories, Spitfire Trailers are manufactured using the Certified 3.5 Ton, 140mm H Beam even on a 1,120kg trailer.


  • This means that if you are purchasing  a  1,120kg trailer you are getting a trailer chassis, designed, certified and built to 3,500kg .


  • The only difference between that trailer and a 3.5  Ton trailer is the tyres, wheel rims, suspension and coupling are lighter capacity to match the lighter load.


This has several advantages to all.


  • You the customer  can be confident  that your rig is not going to destroy that trailer.


  • This is a recipe for confidence, security and keeping resale value.


Does it cost more?


Yes... but Not really.


To use our Certified 3.5 Ton designs on all braked trailers uses a bit more aluminium.


But metal alone is not the main cost factor in production today.


It requires the same amount of holes to be drilled, the same amount of bends, the same amount of bolts etc.


The minor cost in the extra metal is our  insurance, our safeguard for the best quality product for you and our future.


It is a small price for us to pay and Spitfire Trailers are still extremely competitive with steel trailers.

New Model Certification

Spitfire's  800 - 3.5 Dual Axle Boat Trailer is certified and now in production.


Orders placed now will enjoy a delivery in early 2020.

The Benefits of Certification and aluminium

   "The design fatigue amplitudes are well below the endurance limits, and therefore, the drawbar is suitable for more than 2,000,000 loading cycles." 


Independently Certified.

Less weight to tow around.

Manufacturing to independent engineer certification allows Spitfire Aluminium Trailers to be  both strong and light.

Being light increases your payload without the additional cost of going to a higher capacity trailer to carry your load.
