Gates Need Advise How to Hang

[Nyboy]

They are much heavier then I thought at least 300 pounds each. I was going to have 6 by 6s cemented into holes. Then bolt hinges on, nephew thinks weight of gates over time will pull out bolts. What is your suggestion to hang them ?

http://www.homedepot.com/p/YARDGARD-5-8-in-x-4-1-2-in-Lag-Screw-Hinge-328506B/202499833 was going to use 4 of these for each gate screwed into 6 by 6.

Maybe metal posts would be sturdier than wood.

I second Journey's idea, stout metal posts sunk quite deep with hefty metal hinges welded to gate and post..
Although bolted on may prove a better idea should you ever desire to change or have to repair the gates..

H-brace. 2 posts with shorter post nailed in between to make an H shape. Six foot post is a guarantee for failure. For gates that heavy, you need to sink the posts DEEP. If you want four feet above ground, then sink your posts four feet in the ground. If you only sink posts a couple of feet, they will heave and lean. More feet of post underground than above is even better.

Under the H bar, nail another brace, starting just under the h brace on the outside post, slanting to ground level on the inside post. The ends will have to be cut at an angle to fit against the flat posts. This will help distribute the weight and help keep the gates from pulling the posts out of whack.

You can also make your inside post 3 or 4 feet taller than the gate and use a guy wire. This is a support wire run from the end of the gate to the top of the post, secured on both ends. I've done this, it helps keep gate from sagging.

Now, have I made this all clear as mud?

Nyboy, your nephew will really have fun digging that hole.

wow @baymule you really know your gate hanging !!!! @journey11 he was the one that picked them up, not going to be happy digging hole for them.

Harbor Freight has gas auger on sale, $199 and 6" auger bit for $49. We own both. Love my auger! Or you can rent one. Need extension for deeper hole, don't have one of those so can't tell you where to find one.

How are augers in rocky heavy clay? can't dig without hitting rock.

1,000,000 times better than hand diggers!
