    I work Pressure Washing and in the process of buying my first trailer. Most of the last year has been about buying the right equipment and learning the ins and outs of the trade, understanding that this time, assembling my own trailer, would come. The trailer had always been an afterthought and I only viewed it as a way to get my equipment from A to B…now that I’m ready to purchase, would you recommend getting a trailer with brakes? They aren’t required, from my understanding, in my state, but I’ve been eyeing a 7×12 tandem axle trailer, they say was designed for heavy landscaping…but no brakes.

      Brakes are normally required for trailers with capacity of 3000lbs or more. Requirements like that are an attempt at forcing common sense. Yes, if you’re considering a trailer that big, please include brakes. No need to seek a Darwin award.

    I need to get more ground clearance on my trailer and flipping the axle will only add about 3 inches. I am wondering if it is possible and or reasonable to change the spring hangers to something longer to add more total height? The local RV dealer said they could use some “aluminum blocks” to increase the clearance some more but quoted me about $1000 on top of the cost of flipping the axle and while I am not sure what this entails, the cost seems totally unreasonable. I would appreciate some expert opinion. I should also mention I live in Canada.

    Many thanks. Phil

      I agree with you, $1000 seems really steep. You can put spacers between the leaf springs and the axle, but don’t go very high with that. It will make things less stable. Read our article on underslung and overslung springs for more info. Without knowing more of your situation, I’d personally be inclined to use taller hangers or weld spacers between the frame and the spring hangers. You could cut off what’s there, or just add new ones immediately behind the existing ones, but taller, so the existing ones don’t get in the way. Just be careful to spread out the load a bit with spacers that are bigger (longer along the main beam) than the new hangers. You might need to grind the spacers to fit around the existing hangers. Good luck.

      Thank you for the informative website. I have an 20×8 trailer, with the frame only 13″ off the ground. It has a structure built on it. I would like to increase height off the ground by 6″. Instead of flipping axles and springs, can we simply increase the length of the mounts? Or weld a 6″ square insert in between the beams and mounts? We have a complete welding shop.

        Off the cuff, that generally works. Obviously I can’t see your situation, so verify before acting, but inserting a beam between the spring hangers and the frame is a good way to lift things. Lifting 6″, I’d also put a brace across to make sure the extra 6″ doesn’t allow things to sway side to side with road dynamics. Good Luck.

    How do I identify the load rating of the axle on my trailer? There is no data plate on the trailer. Is there a marking on the axle?

      Good question. If it’s not marked on the axle somewhere, we can only make guesses. A serial number or part number + manufacturer would let you call the manufacturer and they might be able to look it up.

    Dear Sir,
    Let me know the size of axle gor trailer capacity 36 MT load in three axles.

      Divide the max required capacity by the number of axles, then round up to the next available axle size. I don’t know what is available in metric axles. Good luck with your project.
