Mobile Gantry Crane Build

I made this gantry to make machine moves easier. It features an adjustable height beam due to limited door height, and a whole lot more.
I thought with this video I'd touch on a few engineering concepts.
I forgot to mention, Being able to level the gantry to within 50 mm means that 2.4% of the weight acts sideways. ie a 1 ton load will need 24 kg sideways force to restrain it. A runaway load can be held back by hand or a rope etc. I felt this was a manageable amount
This gantry was actually finished late Feb, but I had a lot of extra work required first (concrete loading slab for example), and then other commitments.
The design is not perfect. I have improvements that I'd make in future. I might replace the bottle jacks with longer stroke jacks for faster raising

One thing to note I have a commercially made gantry crane 8000 pound capacity its 20 feet long 12 inch tall i beam and can be raised to 16 feet in height even though my shop has only a 14 foot ceiling. The 10000 pound capacity was 10 to 15 feet long but i wanted the longer stretch for splitting tractors. But the point i need to make is according to my owners manual for the crane it warns about the dangers of moving the crane while loaded mine is a pretty heavy unit it's hard enough to push empty so all i do is if i need to move a real heavy load i just leap frog it pick up load on one end of crane and use the trolley to move to other end set it down reposition crane to next position and do the same thing the i beam doesn't twist on you. So now in theory you can move heavy objects through a door with your setup with the swivel legs doing the leapfrog method . Nice build 👍👍 Edit and yes i have a swing chair hanging off the crane lol it just works. And also even though my crane has loose legs but when it is pinned with load on it it doesn't really wiggle and definitely enough flex to keep all 4 casters having equal weight 👁👀👁

If the gantry is on uneven ground it can rock with the weight entirely on two (diagonal) casters. And if the load is near one end of the gantry during this situafion it can potentially have a weight on ONE caster of the full load weifht, plus half the gantry weight. Never skimp on casters! 🙂 Great video too by the way. 👍

I have seen many people moving stuff with gantry cranes. Moving the winch left-right on the beam is normally super smooth, and the easy to do in small increment. But castors always want to swivel, especially when going from one direction to another. When moving "a long way" castors are great, they make the whole thing steerable. But when trying to be precise, they're a nightmare. You try to move forward/back and get an unwanted twist or left/right component. Keith Rucker often struggles with this. May I suggest... Making the castors LOCKABLE to front/back orientation, so they don't pivot? You would then have "pure" forward/back movement from the castors, and "pure" left/right movement from the beam. This (I think) sounds like a useful thing.
@TomMakeHere 3 жыл бұрын
It's a fair point. I do need to move it sideways a little inside the shed. I didn't find it too terrible to use, but I'd probably put the load down, orientate the casters, and the move the load if I struggled. But I might look into adding a lock for just the swivel, it could be useful

You would be amazed at how strong a thin tube is in compression I work out that the casters and the I beam will fail before the tube in my case (my beam is spanning a long distance though) Those sizes sound very robust. It will be heavy, but once it's built it will be a good thing

Arguably a silly question, but would you mind covering how you determined the load capacity of this gantry? Is it just sheer load for the I-beam and compressive load for the A-frames? Whatever the lowest load between those two, that's what your max load for the gantry is?
@TomMakeHere 2 ай бұрын
Need to consider bending and shear of the beam, a central load causes maximum bending and at an end is max shear. Also compression in the a frames, a bit of allowance for the brace inducing bending, and the caster rating. But yes the lowest capacity component is what will limit the rated capacity. It also needs a factor of safety of course, so you aren't right on the limit

NO... be careful... An eye bolt rating "General" drops by a quarter when the load is not 90 degrees but somewhere between 112 and 67 Degrees (~ 45 around the top) when you apply force below or above this range then the rating drops by HALF.

I'd have to go back and listen, I might have mispoken, I meant it will drop to a quarter of the rating for 90°. I got that rating out of the Australian Standard AS 2317. Hopefully the take away for people is to check as the full rating does not always apply

This is a future plan to hydraulically jack the legs. The only problem is that it is expensive
