How do i fit gate posts for heavy gates over a 16 foot span thanks?

Answer 1

make sure that your posts are at least 2ft longer than you need....eg. for a 6ft high gate you will need 8ft posts.Mark the position of the posts on the ground and then excavate your holes 2ft square.......drop your posts in the holes centrally,and fill with concrete mixed 7x ballast -1 cement damp but not too wet.tread in well checking post for upright using a spirit level as you go.will take 3 good barrow loads per hole.make sure you measure opening when positioning 2nd post

GOOD LUCK

Answer 2

Old railway sleepers.

Answer 3

with guy ropes, and securely sunk into concrete and with little weals on the bottom of the gates to take some of the weight off the posts.

Answer 4

I suggest you start with a round steel post. 7" diameter. Put it in the ground 4' in a 16" diameter hole. Fill with concrete.

Now purchase some weld on hinges - heavy duty. Also make a full weld point of flat steel on the gates in the correct position to line up with the post.

You also need to buy a support wheel for the swing end of the gate. You can use a swivel wheel like contractors use to roll scaffolding around-it has a round end. Take the wheel and measure the round end pin - buy a 2' pc. of pipe just the right size for the wheel pin to fit up into. Weld this pipe on the end of the gate at the correct height so the wheel makes contact with the ground all the way along the arc of the gate. You need to make sure the path of the gate wheel is nice and level

and as smooth as possible.

Put wheel up in pc. of pipe and tack weld it to keep it secure.

Line up gate with correct clearance at both ends, brace it in place and weld on your hinges.

Now weld an eye bolt on the top of the steel post facing away from the gate. Take some 3/16" steel cable and run it from the eye bolt (top of post) down to the bottom of the next post-use a turnbuckle so you can put tension on the post.

Prime and paint all welds and metal hinges,etc.

This will take some work, but will last a long time.

You can probably find some scrap 7" pipe at a salvage yard.

If you have any concrete left over from filling the augered hole for the post - pour it in the top of the 7" pipe - fill all the way up if you have enough.

Answer 5

You would need 8"x8" posts,and 1foot  in concrete for every foot in height above ground,heavy duty hinges and maybe a jockey wheel
