Interesting dump mechanism

[284 International]

In place of the chain drive what if you mounted a winch at the rear of the truck frame ans used it for controlled up/down?

That would work, but you would either need to run a pair of winches, or go to a single, center mounted lift arm.

if the winch were mounted at the front, going around a pulley to the lift arm would double the compression force seen by the bed or truck frame. I think swapping the cable(s) each time would be annoying. Winches dedicated to either or loading exclusively would make more sense to me.

After looking a bit, I found an old advertisement that shows the bed party lowered. It is about 3/4 of the way down here, along with some other neat pictures of the Reliance/GMC trucks of the period.

That looks more like the winch idea. Instead of a chain, it seems to be a strap that winds up on the powered drum.

Wow! Impressive.

Look at the tires. Can you image what a dump truck on those tires with the roads of that era rode like? Maybe that is where the "rides like a truck" expression came from

Thanks for sharing!
