Build your own dump trailer

On this page you will find everything needed to Build your own dump trailer. The only skill required when building a dump trailer is being able to do basic welds but if you can salvage a couple trailer frames from a junk yard or craigslist you can pretty much assemble it with nuts and bolts. I highly recommend getting a set of Dump-Trailer-Plans They are very cheap and will save you a lot of aggravation. Just by knowing all of the dimensions and where to put everything makes it well worth it to make it work right. You can go to your local junk yard to find most of the materials such as axles, trailer frames, and tongues. You will need two trailer frames and it will be hinged at the rear creating your lift bed. Then just add your Hydraulic Lifting Kit

You can get dump trailer Hydraulic kits as well as exact Dump trailer plans. below on this page
