Unloading Trailer Attachment

**darus627** · May 23, 2025, 03:23 AM

Discover how I built a powerful and practical unloading system for my car trailer using a 12V wiper motor and a winch mechanism — all powered by an 18V Makita battery. This DIY trailer mod makes unloading gravel, sand, or other bulk materials effortless and fast.

The belt is made from a heavy-duty 650g/m² PVC tarp, ensuring durability under tough conditions. The rear plate is made of 3mm aluminum sheet for lightweight strength, and the entire mechanism weighs only about 15 kg — easy to install and remove when needed.

Whether you're into DIY projects or looking for practical trailer upgrades, this is a must-see mod that will save you time and effort on every job!

Humm, interesting. I have been pondering a similar device on a tow able lawn and garden wagon to spread wood chips along trails in my woods. I had envisioned an endless belt, like a conveyor to pull the chips out.
