Default Calculate gate hinge load??? Who be smart?

I'm building a gate for our area, its 16' long, roughly 400 pounds. I've looked and looked for calculators online but cant quite get the clear answer I'm looking for. I find forums discussing this but they ain't speaking my language and talk about buttons on the calculator I was always afraid to push! Anyone have some engineering smarts in them?

Put a wheel on it and throw the calculator in the lake?

Thought about that, a lot. Problem is it's got to roll over millings, never level, and dirt on either side of them. Seems like a lot to ask of some sort of spring to compensate for rough terrain but maintain some good support.

It's still an option, just not sure about the suspension or bracketry required

OOh you are gonna have it swing open not just slide back.

Ideally. Unless it becomes too much of a headache figuring out the hinges.

Would using two 8' gates be easier to figure the hinge load? I mean I can't do it but I figuring that 16' @ 400 lbs is gonna require some beast of some hinges to keep from saggin', might have better luck long term with two 8' gates if your application allows it ... just a thought.

Definitely a thought. It just doubles the cost of openers and posts, concrete, etc... they do make hinges for this much weight and more, they just jump from 30-40$ each to over 200$each. I just cant calculate exactly how much weight each hinge will see and different sites talk about shear load, radial torque load, etc..

Make your gate post tall and use a support wire to the gate, You can also add one from the post to the fence for more support.

That's a heavy gate. We have a big wrought iron gate, but like someone said above, it's a double gate.

I say why skimp if you want to have a big, fancy gate like that, get the big, fancy hinges and be done with it.
