***Cheapest*** DIY Gantry Crane On YouTube

- We build a gantry crane from two scrap bed frames. We recycle the bed frame's steel tubing to create a truss configuration for the vertical columns. And, we use the bed frame's wood legs for the column feet. Total out-of-pocket cost is only $35.

You guys are awesome! Great job!
You would have had issues welding bed frame steel.
It does not act like normal A36, I think it might be high carbon.
Screws hold lots of things together.
By the way almost every car and truck have two bolts holding the brakes on each wheel.
I also love that band saw! Holy cow, what a saw.
👍👍👍👍
Thanks for watching and thanks for the nice comments!!! That band saw is awesome! We are fortunate to have it in our "arsenal". It was manufactured around 1900 (give or take 10 years) and was originally powered by a flat belt. It has a lot of OSHA hazards, but we understand that and work carefully. I love to hear it start--sounds like a jet engine spooling up!
That's a creative use of the scrap bed frames to make the columns. Nice build! 👍
Thanks! Those bed frames were heading to the recycler at the same time we needed a way to lift the logs to the band saw...so it was a happy coincidence. Thanks for watching!
That's a good question--the tubing is 5/8 inch diameter, 0.020 inch wall thickness (16mm, 0.5mm wall). The long side rails were noticeably bent during daily use by a young teenager, so you are right that the tubing itself is not real stiff. However, in a truss configuration the system is much stronger. Our hoist's max lift is 300 lbs so we have tested this gantry crane to about 300 lbs.
Actually we use it to lift logs up to the bandsaw as well as moving machines around the Shoppe. Plan on using it to pull a motor/transmission out of a 2017 Model T truck
What Stuart said, except its a 1917 Model T Truck.
Good design but how strong is that metal your using from the bed frame? I had a futon frame looked like that and the tubing wasn't very thick, could bend it by hand.

@@keepcalmandfarmon5401 true the truss setup will make it stronger, but one weak link will bring it all down. In highschool I had to build a bridge out of balsa wood sticks, it held 46lbs before it started to make sounds lol. Again nice build 👍
@@jonroland2702 That's funny...I also had a balsa wood bridge building contest in high school physics class! I had no concept of a truss configuration so I placed way down in the middle of the pack. My buddy won the competition, but, his Dad was an architect, so we accused him of having an unfair advantage!
Y’all build a gantry crane just to lift that one bit of wood? 😂
We are all retired, and old so we lift with our brains and not our backs!
you're going to poke your eye out....
That is a constant possibility doing what we do! Thanks for watching!
What's a gantry crane? I want one!!!
🤣Funny! Thanks for watching!
You coulda bought a cheap welder for what those boxes of Self Tapping Sheet metal screws were worth - Wouldnt trust a load on those sheet metal screws, No way
The bed frame tubing is 5/8 inch diameter, 0.020 inch wall thickness (16mm, 0.5mm wall). Much too thin wall to weld with our welding skills. We considered using pop rivets in place of the sheet metal screws...we opted for self-drilling sheet metal screws for ease of assembly. The pop rivets will be "plan B" when the screws come loose. Thanks for watching!
