The spring broke because you didn't install it in the first place. Do it yourself this time and get a spring with 50,000 cycles. It's not much more. This is the simplest job in the world. All the info you need is here:

And this place is GREAT for springs...
You won't see it because it won't happen unless the guy is a 400 pound monster with a bench seriously bolted to the floor. It's amazing how many here will insist that rebar is inadequate and will bend in this application yet not one of them actually worked with rebar or has any engineering...
Thank you for pointing out that the modulus of elasticity (E) for rebar is 29x10**6 psi and the modulus of elasticity (E) for A36 hot rolled steel is 29x10**6 psi. For reference or comparison purposes you may want to look up lead. Young's modulus for lead is 2.0x10**6psi.
OMG there was not one...
Um not exactly true. Guess this column reinforced with 'wire rope' is destined for collapse. Reinforced concrete structures are very complex designs. Not all pieces are stressed as stated above. Steel properties are steel properties. Stresses are then calculated based on the type and magnitude...
Seriously? :headscrat Have you ever bent rebar? Rebar is no more 'soft' than it is 'hard'. The stuff holds up just about every concrete bridge in the USA and is typically manufactured in grades 40, 60, and 75. The properties of grade 40 are very similar to A36 steel and it is probably higher...
I always struggle whether to build for a purpose or build for everything. I once built a beautiful race car trailer out of 2x4x.120 tube (for my race car). As others have stated all the load is near the springs. So that's how I built it. On one occasion I loaned it out to a friend who was having...
Thanks! I think everyone on here started with one post and I have to wonder if any of them actually knew what they were doing. How could ANYONE know anything with only one post? :lol_hitti
Now I have two.
Having built about 15 trailers over the years I find your answer interesting at best. Unfortunately your own answer proves you wrong. Not sure why so many people have this defeatist attitude when someone wants to do something.
"you can not replicate a commercially built trailer for the selling...
