Introducing the Synchro-Link,
the most versatile work truck in the world.
It's a whole fleet of trucks in one and it will revolutionize the way agriculture and construction work will be done in the future.

Synchro-link can change the way we work out of our trucks, save on operating expenses and make daily operations more efficient.

Most importantly: Synchro-link can save your back.
 

One day I was thinking about putting a cube on the back of a new cab and chassis I was about to receive and when I discovered a special price on heavy duty trailer jacks, it got me thinking about being able to take the cube off so I could use it as a job shack from time to time. If I could do that, I could put a flat bed on it for the summer also.

But then I thought about the camper routine I'd experienced in the past. With something being so big and heavy, it would be real tipsy and I was sure it would take up half my mornings out there in the rain trying to change the payloads.
     Then I thought: How automatic could I make it?
     Something like a mini roll off truck was the most logical solution. But to make it work on a shorter wheel base lighter truck there were a few issues  to resolve. Most importantly, the frame rails had to be kept short and I noticed that many of the roll off companys were lowering there pivot points in an effort to do just that to keep the frame rails shorter. But the draw-back of doing so is that it sactrfices some of the dump angle.

I used a match book cover for a straight edge on a scrape piece paper to play around with a few ideas by moving pivot point just to prove my theory on the fallback of lowering the pivot point.  After playing around with the geometry a bit,, I came up with the idea of moving the pivot point back and down with the use of a link member, and it became what one may call a pivotal-link method of dump.  With just a sketch and comparing distances marked on the edge of the match book, it looked as the most efficient way to go.

I call it the Synchro-link method because of the complex operating systems that can be involved when working together with the front telescopic cylinders.

I figured that I could just buy the equipment and build it myself. Having the welding equipment meant that I could build many other kinds of beds for it too. That was the part I wanted to get to, but this is America, things like this just don't happen in your back yard. If so, you pay for it with your life.
