Stress Tests by independent engineers are carried out to ensure the design exceeds the requirements for the capacity by a Factor of 3 X..... Plus.
This means a 3.5 Ton Spitfire Trailer is designed to withstand 3,500 x 3 = 10,500 kg.
Thats right, our 3.5 Ton trailer is designed to 10.5 tons.
Now consider this... All Spitfire Braked trailers trailers are built from our exact same 3.5 Ton chassis and our exact same 3.5 Ton Certified draw bar.
This means a Spitfire 2 ton trailer is designed to a Factor of x 5.25 it's ATM
Our 1,500 egg trailer is designed to a Factor of x 7 times it's ATM and our 1,120 kg Spitfire Trailer is designed to a massive Factor X 9.375 times it's legal ATM requirement.
You want tough ?... Spitfire are tough.
Designed for life... built for life.
So Spitfire trailers are usually manufactured in the following category groups:
400kg, 600kg and up to 750 kg are un-braked and for these Spitfire Trailers use our certified 75mm - H Beam design.
All trailers above 750kg need brakes.
This has several advantages to all.
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 for our future.
It is a small price for us to pay and Spitfire Trailers are still extremely competitive with steel trailers.
"The design fatigue amplitudes are well below the endurance limits, and therefore, the drawbar is suitable for more than 2,000,000 loading cycles."
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 braked capacity trailer to carry your load.
