Making a Mobile Gantry Crane - Part 1
HTML-код
- Опубликовано: 15 сен 2024
- I need to move my machines to the new Machine Shop so I decided to make my own Mobile Gantry Crane. In this part 1 I'll TIG weld the basic frame. In Part 2 I will make the height adjustment and finish with 2K paint.
I normally abstain from comments on RUclips.
Bart, the one thing that stands out whenever i watch your videos is the amount of preparation you commit to on every part as well as every step of the project.
The quality of your work speaks for itself..... I salute you!
Thank you for the comment. It's nice to hear that people see my effort in doing quality work. Taking my time and doing it right the first time, building things that hope to last a lifetime.
I cannot believe you are cutting that steel out there on that really nice patio/masonry floor! You’re a very talented man... make yourself a cut station with an expanded metal top for the saw to sit on, and a hopper bottom to collect all of the abrasive and metal. Add a taped back/ deflector and side rails no taller than the height of the saw deck to route the sparks and metal down into the hopper as well. There is nothing worse than metal slivers in feet and paws you cannot see.
You sound just like my girlfriend .... LOL. Just joking. You are right. I will move to a bigger shop next week and will be making a proper grinding table and welding table. To many projects..... This one needs to be done first.
Where do you think I heard this from! :-) I’m just an old guy tryin to help out you young bucks!
@@trevorjarvis3050 Haha, nice. Thanks.
Great welding skills, respect PRO
Beautiful work Bart. It's a pleasure watching you work at this. Very thoughtful. Proper fabrication. Not just welding and fixing the mistakes.
Thank you
Very good, clean tubing, and clean welds!
Thanks
Those welds deserve to be on a welding manual, nice work!
Thanks 👍
Your fabrication work is clean!
Thanks!
Nice job Bart, very good prep work 👍👍👍
Thanks!
You are like me a lefty in a righty world. Use both hands just because we can and we have an advantage ;) Awesome work mate, cheers from Buenos Aires ;)
Thanks Jorge! Cheers for the lefty's that can weld with both hands.
Nice welds. Can't wait to see it finished. Keep up the good work!!!!
Thank you. Part 2 will be online in a few days.
I've never welded in my life, but from what I saw, your welds are so so neat. I've seen some 'Professional' welders with messier joins than what you have here.
Beautiful work.
Thank you
@Patrick Elliott Because I like TIG. Nice and clean. And I don't have a MIG machine at the moment.
Oh man, my hat's off to you for your patience, TIG welding that whole frame together. The welds are beautiful, but I would have run the stick welder simply because I lack the patience! Looks good!
Haha, nice. Yes I like TIG welding. Btw, Nice channel! How is your Keyway Cutter holding up? Mine looks the same but needs some more down pressure. I will make a fix toolholder with the clapperbox in the future.
Hi Bart, great work. Love to watch you TIG weld... you are very good at it. With regard to how to lift the gantry crane, I think Keith Rucker used long reach, hand pumped hydraulic rams... I think also one of the Polish guys did too... 'Made In Poland' maybe... (sorry, can't remember). I'm looking forward to your solution. Hope the move goes well! Greetings from Southport UK.
Thanks Kevin, I decided to use a Hand Winch to pull the inside tube out of the outside tube just like. You will see it in the second video that will be online within a week.
@@bartharkemametalworks2299 Looking forward to it!
Nice build. I like tig welding to, clean and quiet welding and for me easier to control then mag or stick. Greetings from Belgium. Subcribed!
Thanks!
I also use both hands when I tig weld, I am best with the right hand so far, but I practice... you never know what hand comes in handy ;-) And you project looks great Bart, you are a master welder
Thanks Hendrik, and lets keep practicing both hands. It is very handy for some projects.
Do it right. Do it once. Do it forever. Beautiful work Bart. MfG
Thanks, sounds like my motto
Looking at your Welds, you could either hand. I wish I could weld left handed, I can’t even pick my nose left handed. Nice looking work Sir.
Thank you. And you should start with your nose then ;-)
I never knew welding could look so nice.
tHanks for the video
Damn... those welds are beautiful
Thanks
Very nice job! Well explained and professional 👍
Thank you
I am always pleased to see others using face shields and respirators to protect themselves from fumes and flying debris. You set a good example for everyone in this video.
Lots of welding practice on that project, nice work!
Yep, and thanks!
Man This Is Great👍. Professional welds and advice.👍🤙😃
Thanks
Very nice work Bart. I learned something interesting by watching your video today. That welds can pull metal. I did not know that after you had secured the bottom foot that the side supports could pull the steel, and by that much. It's interesting how materials work together. Thanks for the explanation and I hope to remember that tip when I'm doing my own work. I'm learning stick and MIG diy style. I hope to get into TIG at some point. I love how those welds look afterwards and it looks so much easier to do (looks, whether or not is the case I'll find out 😜)
Thanks!
Nice job, brother!
Right handed or left, Beautiful welds Bart!!! VERY talented.
👍Jay👍
Thank you
Thanks for sharing, I also have to practice my welding skills.
Nice build looking forward to part 2
new subscriber
cheers
Thanks, P2 will be online tomorrow.
Just use a simple crank set-up with steel cable to adjust the height. That's how mine is, and I don't really "adjust" all that much. It spends most of it's time resting on the high strength thru-pins. Also, consider "machining" a delrin slider gasket that takes up the gap between the two telescoping posts. It would be like a square hole "cap" that gets screwed to the larger, bottom post. And that keeps the post from wiggling side to side when you are actually moving things around under load.
Thanks for the commend. I think I will need the height adjustment a little more but we will see. And I thought about a slider, maybe delrin or thin sheet of brass. But I first want to see how it works without and I can always add a slider in the future.
We need to be able to weld with both hands, because we never know which side we’ll have to start from. I see you have 80/20 up there, I build a lot out of that.
OMG. Those welds! 👍
Thanks
beautiful TIG
I think you should pratice both hands because sometimes you need weld with "second" hand :) Kevin Caron made a good video about that a few years ago. Greate video bro.
Thanks, I keep practicing both. Haven't seen Kevin his video so I will check it out. Thanks.
really nice, yes both hands
Thanks
Very Nice.
if you weld the nut on the corner of the tubing (facing the center) the locking bolt will push the inner tube in the outer tubes corner, registering on 2 walls instead of one...should take out any slop between both tubes
nice work though!
Yes that would also be a good solution for many projects like this. The only problem I had was that the radius of the inner tube corner was a lot smaller than the outside tube. Therefor it would only contact at the corner and not the side walls and be less stable. My 20mm bolts that hold the tubes have a tight fit. Fixing the nut, it will slide on these 20 mm bolts to one side. That way I will take out the play in both directions. If there is still to much movement between them I can always add a slider from delrin or brass.
That is cool stuff. I should make my own gantry with my powertig.
Thank you. Its a nice project if you want to make you own.
Very good work.
Beautiful welds Bart.
Thank you
Looking good!
Thanks. Btw, nice Deckel SO restauration. That's one machine I'm still missing
Barts Metalwork thank you so much! 😁
Lovely work. You're really talented. Abom too, of course :)
Thanks!
👍🧒super
Thanks
I had the same problem I write with my left hand but thow a ball with my left. When I was learning to weld I stuck with my left hand but there was one other person I knew and they used there right hand. I can use both hands to hold the torch but only switch to my right when it's in a position I can't reach with my left hand
I prefer to use my right hand for the torch and have a good control with the wire with my left. Switching only in positions where it is better to use my left. It's not the torch that is the problem, I feel I have less controle with my right hand to feed the wire.
I am naturally right handed, almost to a fault. But I forced myself to learn to TIG weld with both hands. Now my 'left-handed' welds usually come out better, probably because I can feed the filler more constantly with my 'strong' hand. Point being, teaching yourself to weld with both hands (MIG, TIG, and stick) will make you a better welder.
Thanks, I'll just keep practicing both.
I really want to build one of these.
altijd een plezier om jou te zien lassen, gewoon een kunstwerk om te zien. mocht je ooit in Noorwegen komen , voel vrij om langs te komen en mij wat tips en trukjes te leren. en ik leer je wat je wilt over bushcraft.
Dank je, en klinkt goed. Noorwegen is een prachtig land waar ik al een paar keer was. O.a. 10.000 km trip op mijn KTM. 4 week en alleen wild camperen. Bushcraft ben ik een beetje mee bezig geweest maar is zeker iets waar ik nog meer over wil leren.
@@bartharkemametalworks2299 wel het is een open uitnodiging, en dat trip die je gemaakt hebt klinkt geweldig, de beste trip die ik hier gemaakt heb is te voet van de noordkap naar mijn huis hier in Valdres het nam 9
maanden in beslag, was geweldig maar ik doe het nooit meer lol, te oud geworden inmiddels. mijn grondgebied of landgoed maar dat klinkt zo pompeus is 7000 mål dat is wel over 900 hectare geloof ik. dus we kunnen geweldige tochten maken op mijn eigen grond, wel mijn 'eigen' ik huur het het kwam met het huis, maar zo heb ik mijn 'eigen' watervallen in mijn achtertuin, bossen berg en meren. nog steeds na al deze tijd een totaal onwezenlijk gevoel. maar het is een prachtige omgeving waar ik mijn basis kamp heb en nog steeds verder bouw aan mijn bushcraft school.
@@bushman4124 klinkt erg mooi 👌. Als ik weer naar Noorwegen ga en in de buurt ben dan zal ik het zeker onthouden 👍
If you have an AC/DC power supply, why didn't you stick weld it? It's faster, and (usually) more forgiving about surface prep. Just wondering........
I like the clean welds from TIG and a need to do a good surface clean for the paint anyway.
Looks great, hope you can put a sketch with dimensions. I need one, but for rough terrain.
Hi Ray, I don't think the dimensions are really critical. Use what material u have and one that fit the size of you shop. Mine: Top beam 230cm. Standing tubes 200 cm, slinding inside from 250 cm to 380 cm height. Leg beams are around 150cm.
Great video, but don't play music in background or your videos will get copyright strikes.
Thanks, and yes. I try to minimize background music but I like to listen to the radio and it's a little annoying to turn it down every time I make a video.
Both hands. Sometimes you can get into places with one hand and not the other.
Yes, i'll keep practicing both.
Mooi werk
Dank je
Why didn't you yde a MIG machine to weld that up? I understand if you don't have one but that machine you have will run stick all day long. 7018 is way more appropriate for that job and is much faster.
I don't have a MIG machine and I like the clean TIG welds. And i'm a little better TIG than Stick.
How to calculate the side column size??
I guess you're going to have to be ambidextrous to weild with either hand .
I'll try
Hé Bart,
Zier er erg strak uit!
Vorderd je nieuwe werkplek al een beetje?
Gr. Jaap
Dank je. Ik ben druk bezig geweest met de inrichting van de nieuwe werkplaats. Vandaag zijn de eerste machines er naartoe verhuist.
May I know the size of the H beam and the square tube?
Which is the stronger weld for steel framing such as this, tig or stick weld, thoughts?
Difficult question. I think it depends on material and welder. For me on this project: TIG. I take my time with TIG to clean everything very good and put a good bevel on the steel. Then I weld one normal pass and then a wave pattern. And I make sure that the first pass goes into the corner. Both at 200 amps which gives a good deep penetration on this 4 - 10 mm steel. With stick welding it can burn a little bit deeper (but this steel is not solid so it's not necessary) and it is less critical to have clean steel and easier to get into the corner. But as soon as there are gas pockets inside the weld the strength will go down. Next to that, with TIG welding I find it easier to lay a good weld in different positions. And with stick it is also more critical to have the right electrode. Last is temperature controle. For normal steel it is not a big difference. For special steels that harden, TIG gives better temperature controle that have a lot of impact on the weld. But for solid pieces, stick could be a little bit better because it gives some more heat imput (in normal use). Beside welding, I think it is more critical to have a good design where there are no great forces on the weld itself. Press or pull forces are better than shearing forces.
@@bartharkemametalworks2299 Thankyou for your comprehensive reply. Your explanation would generally be my thoughts also. Gas pockets are always an issue wuth stick welding where as tig is clean, tidy, accurate and more pleasing to the eye. Thankyou 👍
Usually your torch hand is your drawing hand.
I prefer right but draw with left. My problem is more with the wire control than with the torch.
Your welding looks great but who has the time to waste doing so much prep when you could just mig it? Plus who engineered the job? Not trying to be an ass but I been in the business for 45 years.
Yes, no problem. Functional comment. I don't have a MIG machine and I like TIG welding. And I want to do a good prep for the paint anyhow. Engineered by me. I (think) I know what I doing. I made this for 'light' machines, max 1000 kg and only straight lifting. I watched a lot of commercial ones and I am confident it will be strong enough.
@@bartharkemametalworks2299 great looking job. Best to be safe all the time.
Grt work... keep up
Thanks 👍
I would give my left arm to be ambidextrous...
why tig , it looks like your right on the edge amps wise , and if anything looking a little cold.
but nice work.
I like TIG for the clean work and easier (for me) to weld in different positions. The amps where alright (it's only 4 or 10 mm steel). On the 10 mm I could use stick and burn in a little deeper. But I believe this is strong enough. With a good bevel I could do a first pass at around 180A and then set it to 200 for the wave. Maye the steel looks cold because I use a little higher gas flow than normal and with a gas lens I keep the steel for oxidation. But welding the first pass and then the slow wave did put in a lot of heat.
Здорово
I'd give my right arm to be ambidextrous...
Haha. At least you would be a good soccer player ;-)
You're not welding right. Your supposed to be on the floor with flip flops on. Lol
I say both
давай 2 часть побыстрее
One week ;-)
Having designed, built and installed a few hundred of these in my life, my biggest concern it with the TIG welding. Never have felt good about it in any lifting apparatus, but it's your life not mine. Why? Because you don't get a good penetrating weld with it. Also, you do tend to talk too much, wer can clearly see what you are doing. Reduce your talking by two-thirds and you'll be fine, also your videos won't need to be so long.
Now go buy or rent a MiG and use 70 KIS flux core wire. Throw all the other stuff away and test it at 125% of the load and put it through all it's paces every year you need to do that. No charge this time for the consultation.
Ken Parnell wow another internet expert
@@esimler As it happens I an an expert on cranes and material handling devices, and no one TiG welds any of it.......ever! Don't say you haven't been warned when the stuff comes crashing down.
Hi Bart, more artwork from Bart's Art Studio!! Impressive work as usual and i can't wait to see the gantry in action for real. Check out this guy to see how he deals with his tig corners (ruclips.net/video/NQ4nbxz9o4c/видео.html). Thanks for sharing. Stay safe and keep up the good work. 👍🖖🏍
I'm making a similar one now, watch my last video.
Hi Sergey. Nice project, nice shop and nice YT channel. Subscribed. To bad I cannot understand the langues. But it was fun to see you struggle with the heavy top beam. I'm not looking forward to do that with mine next week. It takes a crane to build a crane...
@@bartharkemametalworks2299 Bart, Yeah, it's a tough literal project, good luck with yours! Take care of yourself.
Well I guess there is more than one Bart that welds . pipeline welder of over 45+ years . you can see me in a demo www.fittergrips.com .Nice work so far
Thanks Bart, and nice demo.
@@bartharkemametalworks2299 thank you back
Yeah, Hi Bart..Could you spend an hour or two putting together a sketch of all your dimensions , including your shoe size and the distance from ear to elbow while enjoying an ice-cream, Well because I'm an idiot that shouldn't own ANY TOOLS, let alone fabrication tools. But HERE LET ME TELL YOU HOW YOU SHOULD BE DOING EVERYTHING BECAUSE I MATTER !
Bart, I wanna partially apologize for the following. But since YOU and allot of folks on here are just TO NICE and wont put stupid in there place, The following contains instructions and suggestions for the sexually confused commentators!
Dear, Concerned and extremely irritating commentators ,
IF YOU CAN'T BUILD A SIMPLE ROLLING A-FRAME TO HANG A HOIST FROM , YOU DEFINITELY SHOULDN'T BE HERE BOTHERING BART OR ANY OTHER PERSON ON RUclips FOR THAT MATTER WHO HAS MASTERED THE ABILITY OF COMMON SENSE, FOR DIMENSIONS...AND IF YOU, THAT SPECIAL LADYMAN, HAD THE AUDACITY TO GIVE BART GRIEF FOR CUTTING STEEL ON HIS "PRETTY" PATIO, OR IF YOU, THE ONE WITH NO FRIENDS, FROM HIGH UPON YOUR ESTROGEN FLAVORED PONY YELL DOWN INSTRUCTIONS ON HOW HE SHOULD OR SHOULDN'T BE CUTTING STEEL, YOU NEED TO JUST STICK WITH BAKING MUFFINS AND FINDING NEW PLACES TO STICK YOUR SONIC TOOTH-BRUSH , YA SEE CUPCAKE , THIS IS ACTUALLY HOW THE REAL WORLD WORKS. THE CHOP-SAW DOESN'T HAVE A "PERMA-HOME", IT'S USED ON THE SPOT WHERE YOUR WORKING, AND IT DOESN'T WEAR SILK PANTIES TO CATCH SHIMMERING UNICORN FARTS! THE 40, 80, 100 MICRON LENGTH IRON, ALUMINUM, ALUMINUM OXIDE, ALUMINA, BORON, ZIRCON , SILICON, ETC PARTICLES EJECTED BY THE CUTOFF SAW HAS NEVER IN THE HISTORY OF MANKIND, THAT'S "MAN"-KIND TO BE CLEAR, EVER BEEN THE ROOT CAUSE OF ANY "SPLINTER", ...EVER!!!!!! WHY? BECAUSE THEY'RE FINER THAN THE DIRT AND ROCKY DEBRIS THAT LAY BENEATH. AND AFTER A GENTLE BREEZE, OR ESPECIALLY A GENTLE RAIN THEY LITERALLY MELT AWAY BACK TO THE CHEMICAL STATE THEY ORIGINATED.
Hi Bryan, I don't really mind the questions and comments. It's nice to hear from people and see there reactions. And sometimes I learn from it. But how I react to the reactions is always a choice I can make by myself. So thanks for yours. Btw, ear-elbow-ice would be around 40 cm ;-)
