- Quick overview of my homemade gantry crane. I've used this crane for about 1 year thus far, it's one of the most useful DIY projects ever.
Parts List:
Lumber: 2x 2"x10"x8' and 11x 2"x6"x10'
Chainfall Hoist
Casters
Screws
Manual Labor
That is a great Crane !
Best build here on UA-cam. Thanks for sharing!
Thanks for the kind words!
I’de be interested in learning more about your shop. Looks great!
Nice shop ,great presentation.I prefer carriage bolts for heavy loads with wood,I built one years ago in the field to repair a tractor,used 2x12s for top rail and lifted a very heavy old tractor,approx 8000 lbs.i just built a 8x8x 12 high rolling scaffold to work on my shop ceiling, since I am a one man band,I am constantly putting wheels on heavy stuff.
Hi . Could you please tell me what size of the cargrige bolts that you used. Thank you very much.
@HoangNguyen-in1lo
Been too long,don't remember exactly sizes,but I never use less than 1/2 inch diameter carriage bolts. Generally use lag screws and pre drill for static medium loads.Dynamic heavy loads I use 1/2 inch or larger carriage bolts with big flat washers on nut side.The washers are very important,I even use washers on anything structural,even # 8 & 10 wood screws as they tend to just bury the head and not pull the pieces together.Remember to pre drill and or dull the point of the screw to prevent splitting the wood.Sorry for the extraneous answer ,just thought it was necessary.
@@randolphsnyder1505 Thank you so much for the information I’m so very appreciate . Thank you.
Good video. Matter of fact I'm getting ready to build one with exactly your same material list, wood.
I do plan to make a couple changes.
1. Using waterproof glue for the vertical posts. I believe that will eliminate most of the twisting.
2. The feet apparatus will also be glued together and to the vertical posts.
3. The four 45° vertical post supports, I'm going to lengthen those to attach about 6 feet up the vertical posts. That should create even more support.
4. Using all thread 3/8" rod i'm going to use at least two of those at each joint on the horizontal beam along with heavy washers and double nut for locking.
5. Going to use all-thread bolts on the lower joints as well.
Thank you for your video. Was easy to understand and I didn't have to rack my brain to figure out a good design. 😁
Good stuff, I like your plan. Especially the glue on the verticals for twisting.
Great design. People sometimes underestimate the load capabilities of wood, I have lifted some extremely heavy things from wooden supports in the past
Amen, raised a 32 foot steel beam for an open concept house renovation. Spanned the entire length of the main part of the house. Built a wooden three point hoist system and was able to lift it right into the ceiling.
Maybe one more swivel caster directly underneath the posts? Enjoyed the video. What a awesome garage!
Thanks, and great point about casters under the center. I might add them next time I need it. Have a good one!
Nicely done. Thank you for the specks.
Excellent build, great video! Thanks!!
Excellent vid, Bob! Thanks for taking the time to put this together. I’ll be building one based on your design.
Cool, glad to hear. Let me know if you need any specific dimensions etc.

Nice shop!
Life and pocket saver, darned good job 👍
(And back saver) :). Thanks!
Did you glue the vertical supports and use bar clamps to let them setup ? If not maybe that's a way to reduce them from warpage. Kind of like making a glulam like in houses for floor support. Your project looks great only one thing i am going to do when making it like yours is making a longer sled on top with extra pins welded to make the chain where i want to if i have lift something off center. Great build good job bud.
Nice job. Great video
Very well designed unit!!!!
Thank you thank you thank you I was hoping you would make a video of your Crane I don't know if you saw my comment about wanting this video from your older video but I appreciate it as always excellent work
Cool, glad you liked it and yep, I made this video after reading your comment. Have a good one and thanks!
Excellent video 10/10 Thank You!!!!!
Glad it helped!
Excellent workmanship and explanations, thank you for posting this.
Cool, glad you liked it. I hope it helps someone build one for themselves.
Bloody marvellous. If I built one I'd have to build a hutch to house it in.
If making another what would you differently?
I'm just presuming you used timber because (like me) you can't weld ..yet!
Thanks for great, great explanation.
Thanks. I think I'll do mine out of white oak lumber that came out of an old home.
Very nice.👍
Great inspiration, thanks…
Nice video. My personal only size criteria is I can drive my pick up truck between the legs.
Yep, this design fits over a full size truck bed. I unloaded lots of stuff this way
at 3:11 as a mech engineer yes yes it does make a big difference
if you have the pin alone then that creates a point load that all the force concentrates on
spread over the 1ft that you have it as creates a pressure load for lack of a better term the overall force is the same but the area is much larger exposing the wood to lower pressures and stresses in general, also another benefit is if you have non perfect wood that might have internal weaknesses a single pin design may break that where as this has no chance of doing that
the one thing i would have done as a possible improvement is to put two strips of flat iron on the top of the beams, steel on steel friction is quite low and would decrease the wear on the tops of your beams from the steel sliding across the wood
also if the casters are rated at 2000 combined that would either mean that they are 500lb a piece or if that is 2000lb rated casters they are overkill for this crane and should be the last thing to fail as loads are divided equally when the system is symmetric, so if you have your load in the middle of the gantry both legs see the same force which is half of the load you are lifting then each caster sees half of that.
grk screws are not deck screws, but structural screws. (good choice).
Great project . What type of wood did you use
great job
Thanks for sharing your build, and the safety precaution that was emphasized during and at the end of the video. In the DIY world, safety has to be the number one concern when undertaking any project that could pose a risk for injury or death. Having said that, would you change anything in your grantry if you had to build it all over again? How many years of life do you expect to obtain from a wooden gantry such as this one? Keep up the good work!
Thanks for the kind words. I wouldn’t change anything from this design for my personal use. If fits over the shelves I build so storage is easy, and the size is good for my use. I think it’ll hold up for the rest of my lifetime. It lives in a climate controlled building, so there’s no environmental factors to degrade the hardware or wood. I’ll be using it soon for another project, it’s been a real back-saver.
Have a good one!
Great video and very helpful! I am about to build one. My thought is that the point of failure would be at the bottom of the vertical legs. Some weight is distributed to the casters via the 45 degree supports, however most of the weight is being transferred to the bottom of the legs and rely on the rated shear strength of the grk fasteners combined with the strength rating of the 2x6's between the casters. Maybe an additional caster directly under the legs would work? (A block would prevent any mobility under a load). Have you noticed any stress to the 2x6's between the casters when under a heavy load? Thanks again!
yeah, if you wanted to avoid that I'd just add another caster directly underneath the load...but then again if I were picking up something that crazy heavy this probably wouldn't be the tool for the job anyway.
Is that a C or a CA sittin' in the corner? That is a fabulous lookin' Allis Chalmers restoration!!
Excellent eyes! Yep, it’s a C
I appreciate the test period before posting! The simplicity of the parts list is great. Could you send the measurements? I've got a 17' Mud Hen sailboat which needs a bottom job and some centerboard work. Thanks Again!
Out of curiosity, why not grease the top of the boards for the trolley? Should only help things out.
I am thinking you could re enforce this with some angle iron or square tubing
Thank you so much man.
Right on, good luck on your project.
nice job I have to build a smaller version of this (not as tall)
I would like to know how to add small push mower or lawn mower trailer tires for wheels, so it can roll through a yard that is not paved.
Lots of options for that, but obviously that would severely limit the capacity.
@@BobWilson84 I have to do a swap on a small four cylinder engine. I do not have any kind of a garage or a flat paved surface and I am severely on a budget reviving a car I do not want to give up on.
I have not done an engine swap either, but I bought a Hayne's manual. lol
I think I could do it if I can figure out the lifting of the engine part.
Is the trolley hard to slide under load? I"m looking at using rollers instead of sliding contact
It slide ok up to about 200 lbs or so, especially with some grease on the slides. Rollers would be the way to go if you planned on needing that feature often.
I need to build a gantry crane. I need it for riding lawn mower, wood chipper, tiller and to rebuild truck engine, etc. I really like your design. I like that you thought this through and waited a year to put it on here. What are your thoughts on load distribution if I made it 8’ or 7’?
8’ or 7’ wide? Or 8’ or 7’ tall sir?
8’ is best for me
I was getting distracted by the east chair on castors in the background. Lol
Hahaha, I’ve done a lot of sitting and rolling
Hello, Really like the crane. What were the length of screws you used and diameter? Thank you!
I have gathered all the materials to build one of these. But today I’m obsessing about whether to build it short enough to take it outside my shop. If I do that it can only be 8.5’ tall. It’s only a gravel apron so maybe I’d never use it outside anyway
I also have gravel outside my door, and I used it in the gravel once, I didn’t feel safe halfway through the lift and aborted. After that moment, I’ve kept it in the garage. I think you should keep as much height at you can, it’s very helpful to have space for the chain fall and room to move around.
2 years into using it I have to say I’m glad I built it. I use it quite often for many things like routine like lifting the mower or most recently repairing tractor axles.
That is awesome, very nice work! - I need to build one right now!! A few important questions in my mind though...
How easy (or hard) is it to slide that angle iron trolley from one side to the other when there's a heavy load attached?
How best to slide the trolley - by pulling on the load chain while holding on to one of the legs??
Do you feel the crane is still stable when a heavy load is slid all the way to one end of the beam rather than centered?
Thank you!
Hey Gary, it doesn’t slide very well with over 100lbs on it… and since it’s on wheels the whole frame likes to wander when you try. I have lifted about 1k all the way to each side, it was very stable in that configuration. This is the type of tool that once you own you’ll never understand how you lived without it
Made in America! How'd you get those letters at the top?
Yap.
Can you post a link where you got the casters for this project? We're going to use this design, just need the casters.
Harbor freight has a large selection of various casters. Calculate what you plan to lift + about 300lbs for the crane and hoist. Then divide by 4 to get how much each caster is supporting, then pick casters which are rated about 2x that value for safety margin.
👍🏻
Could you tell me what measure and what exact amount of screw you used
I'm planning to build one to do a cab swap on my f250. Do you think this design will handle that??
Thanks!
What generation f250?
Did you attach the casters with screws or bolts?
Is that yellow pine
I can’t wait to make it. Great job
Great job I just wish the wood was cheeper
No kidding! That project cost doubled in the last 4 months!
Why not just weld it up out of steel? I'd think you could make it stronger, for no more money, and probably quicker to build.
Wood is alot cheaper than steel
Calculations put the load rating on the beam at around 3300#. You could have used a 2X6 for 1000#.
I’m looking at just wanting 1000# lifting and using 2X8 which calculates to about 2500# lift rating across the beam.
Like you, safety margin.
Trust, but verify… I like you. I used similar equations for point-loading on open spans.
Solid planning on your part. I hope it works out well for ya. Go hit that lumberyard and get started!
