"A" frame gantry

[Frank S]

Knowing I had a large toy arriving this weekend I knew I needed something substantial to help lift it off the trailer.
I decided to build an "A" frame gantry for this task. the gantry is 15 feet tall 12 feet wide inside with a 10 ft stance to the legs.
Made out of 6" pipe and a 12" heavy "I" beam with a length of 8" H beam capping the top center to help prevent twisting under the load the braces are 4" pipe
I used my 1+1 to 3 rule for width to height ratio from the vertical center line to the ground for every 3 feet in height the legs extend 1 ft in opposite directions making the base of the legs at 10 ft to the height of the bottom of the beam 15 ft making it very stable against tipping
the beam is embedded between the legs by cutting out a receiving socket
Note the short piece of beam being used as a template to layout and cut the socket for fit.





Tomorrow we will see if my efforts were in vain or if the A Frame will be come of some value around the place,
If nothing else I can convert it into a swing set for the great grand kids to play on
