Homemade mobile gantry crane

[@edd1016]

Nice system for elevation, best I've seen.

[@kevinhornbuckle]

These welds will hold just fine. But as you get more practice, you will turn up the amps a bit to get more penetration and more consistent weld profile.

[@raulespitiamelo6795]

Excelente construcción muy práctico y funcional muchas gracias por compartir sus conocimientos y experiencias

[@TheTiger4787]

Great job my friend. I wish i knew how to weld in order to build this. But i am inspired by your work.

[@capiberra4118]

Nice work, thanks for sharing. Cheers!

[@kokmil]

Thank you!

[@jaba512]

Great build. I am not a certified welder, but you would get better penetration and cleaner welds if you would clean the millscale and surfacerust before you weld the steel. With clean base metal the welding becomes easier. Keep it up !

[@kokmil]

Thank you for your feedback! I will take your advice. :)

Bill needs braces from the centre to out side legs stop swaying when moving or pushing it it may be fine just i would put braces in Plastic wheels i would use steel wheels as plastic wheels will pick up any small stones or steel bump bump just like a super market cart You made a great job of it just me i like too make sure that it wont fail as you know some people will over LOAD units like this Take care and all the BEST Barry NZ

Weld prep? Just saying i wouldn’t trust that with out the prep

[@briankarnowski5614]

That plate to I- beam weld looks like it's quite cold, no penetration! I wouldn't trust it!

[@WFKO.]

brother bought a Twin Rotor rake, built in factory and half of it just fell off. I think this welding is better lol.

[@Dancing_Alone_wRentals]

Looks nice. Great video. Oh....I'm the 151st comment on the 151st day of 2022. Hmmm

[@dannyroberts5056]

I realy like the design of the adjustable legs. One question I had is did you drill a hole in each upright for a pin or heavy bolt. If not it may not be a bad idea. I have seen cables fail over time expecially if left outdoors in the elimates. Great work and it came out realy nice.

[@kokmil]

Thank you! I drilled more hole on the ajustable square tube. I can set the high in about every 30 cenimeters.

[@dannyroberts5056]

Nice. Again you did a great job.

Nice job!

[@davidcrumrine1165]

Those welds sure wasnt worth pausing on them for a whole minute. Next time clean the steel especially on something structural and your going to be under it. For one would have gotten way better looking welds but the main reason you would have gotten way stronger welds with better penetration. I really think social media and KZbin really need to start checking videos and anything that people post that isnt safe needs to be removed because these platforms has turned everyone into professional in stuff they dont have a clue about and pass on the same unsafe practice to the next guy who thinks i watched 2 KZbin videos i am a pro and can do it myself.

[@gary6570]

2 Pedictions... 1 - welds will fail due to welding on rusty metal AND he 'pushes' the weld instead of 'pulling' which results in shallow penatration. 2 - paint will peel (again failing to prep the metal.

[@kokmil]

1 - You have right about the metal prep. In my next jobs I will pay more attention to it. 2 - I sand the frame with a "80" sand paper, and wiped it with a rag. I bought a combined paint (primer and top coat in one). The seller sad it did not matter if the metal surface a little rusty.

[@timsaveneh567]

MIG push is fine, nothing wrong there. Could have done more prep but the beads looked fine. Probably right on the paint front.

[@briankarnowski5614]

Mig with shielding gas you generally push. Flux core wire you drag. Clean weld joints to shiny bare metal first and crank up the amos, way too cold!

[@efields1201]

I guess if the weakest link is the plastic wheels you should be well within strength of the metal should the welds hold even w no prep

[@brotherscooperation1737]

hello, u have any link or recommendation to buy that wire rope?

[@kokmil]

I can link where I bought the hand winch, but it is a Hungarian webshop, and the winch with the shipping price will be expensive. I bought the cheapest winch what I found, because do not need to lift heavy weight.

hello, what is the wall thickness of the square tube?

[@kokmil]

Hi, The legs were made from 60x60x2 mm square tube. The top of the "A" shape (I don't know how it's called in English) was made from 6 mm flat bar, and the adjustable parts are 60x80x3 mm quare tubes.

Hi.. can you please tell me what specs is for the beam ( inches on deep, inches on flange and the material thick... I need build one 20 feet long and 12 feet high and I need use one beam with 4 inches flange but I'm not sure the thick of the beam and the deep that I need to buy and the square tubes thick.......thank you

[@kokmil]

Hi, I used a 2,5 m long piece of INP140 I beam. You can find the dimensions on the internet. For the legs I bought 60x60mm square tubes with 2mm thickness. The type of the materials are highly depend from the planned crane load.

That Metal is pretty rusty to mig weld on without cleaning first

[@Douglas1ro]

Flux core is a lot more forgiving than mig. hich is probably why his welds looked as good as they did, but still, you are right, should have cleaned better.

[@glyn1]

needs braces or it will split --wheels wont take much weight wheels should be steel not knocking it you have done well just thinking of safety factor
