I have to say here, I made about 8 steel coasters for my garage in doing this. It may not seem it, but a cross member holding a small car engine might not seem like much...but if you design and build a system and it fails structurally, that small engine and the beam attached are more than enough to kill someone when they are falling. In any event, I simply took measurements of the offset and incorporated that into my final measurements. 4 Ton Gantry Crane Build. They helped me take my CAD file and correct mistakes, and get it ready for the laser cutter as G-Code. Did you make this project?

Pin Hole Diameters: As indicated, I did use a lathe to remove some shoulder of my threaded pins which I scavenged from the used 4-wheel trolley bodies I bought on Ebay. If you can afford all new materials from the steel yard, by all means go that route...but in my case...I went the "upcycle" (read: poor mans/junkyard) route and got my primary structural components from used materials. Gear-obsessed editors choose every product we review. Since I had a starting point for my main structure as a used pallet shelving system, pretty much all my design decisions revolved around that. I think that's the balance on 'building a tool' is "can I safely make this and do it myself"...and obviously a crane pushed that to a sorta extreme case. Notes on Making the Top Plates: I need to note here that trolley top plates were made in a two step process of cutting flat plate and the holes on the laser, then secondarily bending the ends in a brake. The legs, especially the front, could spit out sideways under heavy load.- racking units are designed to sit squarely on a flat level solid surface. @nikita: thanks for checking it out...definitely useful. That...was a bad idea. Man....talk about crafty, those folks couldn't even google it...so imagine trying to come up with that thing on your own! In my case (and this may vary if you choose to attempt this), I used the mock up to assess and finalize measurements for several aspects of the trolley bodies. After everything was assembled, I needed an actual way to lift things from my newly set cross beam. This is known as ‘permitted development rights’. Thanks again for checking it out! Original File URL : https://upload.wikimedia.org/wikipedia/commons/4/4... Now that you've decided WHAT you want the crane to do...and you have at least sorta sorted out what materials you have on hand for re-use...and what tools you have, you can start to design your crane. I did have to trim the feet of the rack, as the floor plates were wider than I needed. Industrial Office Store Closing Auction: A local big box office supply store was going out of business. Alternatively, I have found that people who work at places like steel plants, manufacturers, machine shops, etc are surprisingly open to helping the occasional hobbyist if you are respectful, you respect their time, and you have an earnest desire to learn. No matter what tool you're making (including a gantry crane) doing a little googling and seeking guidance isn't cheating...it's learning from others (as long as the project is just for yourself...otherwise I hear they call it copyright infringement or something!) Further, I have no 'true' way of knowing the load rating for my gantry crane. This first example (what I will call the Equals Sign ‘=’ gantry) is I think the most common I have seen among beginner gantry designs, but it is not a good solution. It's part of a Jeep FC170 build that's underway. Once I had played with the plywood mock up, I was able to see my trolley body idea in real life and come to conclusions on measurements, wheel placement, etc. love the bridge build you did! I went there during the last days of the auction/sale and bought two pallet shelving systems. I like using mock ups of cardboard or wood for things that will eventually be 'made real' in steel. ...and don't be shy if you "can't draw"....you're drawings don't have to be Picasso sketches...you just need to make enough lines on the paper so you can think about what each various design does in terms of solving your problem (in my case, lifting stuff). I can guesstimate as a layman what it's max likely is, but guessing isn't a safe game when it comes to overhead lifting and safety. I did a number of tests lifting small items of about 100lbs and then using a ladder to climb up and inspect the entire rig. - The pallet rack which uses holes in which the beams rest, have small retainers meant to keep someone from accidentally 'lifting' a cross beam out of the holes. While I managed to wrestle all the (sorta heavy) parts up onto the frame and get them assembled, it might be wise to think about the final assembly process in some depth, to avoid issues. But when they're sized down to more … - The motor in the last photo (hanging from the hoist) is a 4.8L small block Chevy fully dressed. Once you put this thing on casters there is no such restriction and any leg could spit out sideways.I just want to say again I love the ingenuity, I love your concern for safety, I'm not being mean. ...and yes on the farmers comment...they are some of the craftiest of crafty folks! on Step 12. Thanks: I appreciate that anyone even read/looked at this Instructable. I ended up buying a new chain fall type hoist. While this project was fun, I realize now I could never in good conscious sell this tool to anyone else for fear they might overload it and get injured. This garage crane (mini gantry) is fully adjustable up and down, then with the I-Beam Connector Clamp (Free Plans) the crane also adjusts width-wise so it can fit your project — and your available garage (or shop) space. Also two of these photos are the final CAD DWG files I used for cutting my trolley bodies on a laser cutter. Workshop & Garages. As such, I have not included specific dimensions/etc for reproducing this build...rather I've tried to just show how you might approach a larger scale tool build for yourself, some techniques I used as well as mistakes I made. thanks for all the valid points, and raising them...as well as the very nice comments!

Sometimes, you can just buy it cheaper than you can build it. I could have possibly made some on a lathe, but that seemed tricky. It is so easy to get badly hurt.The only ways I can think of to determine the strength of this machine are:- to hire an engineer to do the math figure out a number, which could be wrong. A pre-built DIY Gantry Crane kit like this will consist of purchasing the necessary parts that have already been built and conveniently packaged for you. By the time I had wrestled the first trolley up and got it assembled, I really regretted not thinking about HOW the tool would be assembled once I made all the parts. Those final CAD drawings only came after a LOT of pencil doodles, and plywood mock ups. As long as you don't plan on liftling a whole car it should be totally fine. Adding Caster Wheels: I wanted the crane to be able to 'roll around'. Dec 20, 2015 - This Pin was discovered by Craig Mason. While at first I was like "well this project is over"...then I realized I could just narrow the pin shoulders on a lathe, and about an hour later, I was back in business. It's a lot easier to make pencil drawings and find problems, than it is to start building and run into troubles there once you have a welder in your hand. I found I could buy USED beam trolley assemblies on Ebay so cheaply that the shipping was almost more than the purchase price...so I did that and just stole the wheels out of the used trolley chassis. I really enjoyed this, thank you.And you're right, farmers can fix anything! Yah...I was able to lift cast iron V8 engines without any issues...I'll leave the whole car lifts to the hydraulic jacks! good luck with ur projects!

I watched a video over a year ago and have been hooked since then. I'd just encourage everyone to set some minimum requirements, but not to go crazy and get into a situation where you make your project so hard, it can't be finished within a reasonable amount of time, at a reasonable cost. Mocks ups are low cost ways to evaluate and 'see' what you've designed...the idea is that mock ups can be created easier and cheaper than the real thing. Commercial Steel Plant: Lucky for me, my local steel supplier is close by, and also very friendly to individual purchasers buying small amounts...even though they normally sell material by the truckload to coal mines and other industrial scale buyers. It only took 30 minutes to cut and assemble the mock ups. Whew, that's a lot of boxes of paper reams! Lay the I-beam upside down on blocks on a level surface and slide on the gantry trolley. Once I had designed my trolley bodies with a pencil, and scavenged the used trolley wheels and pins from the used Ebay sourced trolleys, I was ready to build a plywood mock up to see if my idea worked like I thought it would. Mechanic Garage. Sourced Materials: The dimensions and unique structure dictated by the used pallet shelving superstructure defined my design in many ways. You start thinking of all the possibilities that having your own Gantry Crane would create but it is too expensive to … Glad you like the bridge build. While you may source different parts requiring differing approaches, hopefully this Instructable encourages others to get out there and build stuff. 2 LITERATURE REVIEW LK Goodwin CO. is a material handling equipment company that sells many types of hoist’s and cranes for certain applications. Mechanic Garage. I just picked a decent spot about halfway down, and used the rack's pin system to drop that third cross beam into position (it is still removable). When designing your system, don't go it alone...fall back on makers who came before you (including the folks that build the first Shadoof!) Looking through their list of portable hoists, a 2 ton has a cost 20. I did have to modify the pallet shelving a bit to make it serve my purposes, and here are a few of the things I had to do: Shortened Overall Frame Height: I wanted the gantry crane to be able to roll in/out of my garage which meant it needed to clear the garage door opening which is 10' I used a plasma cutter and shortened the four corner posts, allowing for the height increase from caster wheels I was also adding to the base of the frame. Using a laser cutter makes you feel like you could honestly make anything...if you're having a bad day, I highly recommend a dose of laser cutting...it makes all your problems go away! A fixed position static system for lifting is probably a better way to go. Now, post completion, I'm far more confident in my ability to do that, and the education I got in this exercise will help me on other projects. It’s easy to use, easy to adjust, and easy to disassemble for storage or portability. Obv that's prob a distributed static load, across several tiers of shelves (because as noted earlier, the max load per horizontal beam pair was 4950lbs when the units shipped new from the factory)...but wow...28,000lbs? Cost can get away from you easy, and little things can add up. Thanks to the patience of the guys in the shop helping me, eventually I got it right, but not until I'd definitely wasted some time and plate making every possible wrong size I could in the brake. . These types of cranes are wide enough to straddle an object and strong enough to lift and lower it. While searching for ideas for my gantry crane, I learned about the "shadoof". Understand the weakest part of the device and NEVER approach that limit. What a great idea. Modifying Structural Pins: Fortunately, I have access to a lathe and was able to turn down the shoulders of each of the used trolley pins so that they were narrow enough to fit my beam width. Big shout-out to my friend MattJ who envisioned this build...the second he saw the shelving in my garage, he had the great idea to build one shelving system into a gantry crane...big thanks for the idea. It's a Shadoof! Availability of materials and how you source them can impact and dictate overall design...and it did for me. The most fun part of this project was probably cutting the trolley bodies and top plates on the laser (and bending the top plate in the CAD brake). If you select the DIY option from Chart Garages, we aim to ensure the assembly of your new building is as straight forward as possible. Intended Use: What I needed to lift/intended use defined many aspects of the tool build (mostly automotive bodies and engine/transmission assemblies), Environment: The space the crane would operate in (my garage and driveway). rennaker331 says: January 27, 2019 at 9:12 pm I love your videos. Saved by HomemadeTools.net. Offset Beam: My choice to use the pallet rack came with the hassle that the beam the trolleys ride on had a 1" offset on the inside (a lip of sorts). About: I believe places like the Instructables community are important for encouraging others. Gantry cranes are those large structures you see in shipyards that are used to unload shipping containers. It's good to be creative and explore alternatives places to get materials. NOTE: Credit to Wiki Commons for the Shadoof image, via Sir John Gardner Wilkinson / Public domain. YOU, MY FRIEND, NEED A GANTRY CRANE!!!

It might just save you some time (and your sanity). Then after analysis of the failed structure cut it up and throw it in the scrap bin so stressed pieces can't be used again.I love the idea, ingenuity and creativeness. https://upload.wikimedia.org/wikipedia/commons/4/4... How to Make Charcuterie Boards Using Clear Acrylic Templates. ;-). Reply The only thing you will need to do after that is to put the pieces together as instructed. If I'm reading it right the entire rack as a whole is rated to a max load of 28,000lbs. Cost: A decent overhead trolley system can be purchased new for under $1000 in most cases (at least in the US). @michaelg251...you're totally right and great advice. Make sure you pay a visit to your local farm store...they often carry heavy duty materials like chains, hooks, clevises, and other such things which are industrial grade for yanking tractors out of ponds and such...so the occasional browse of the local farm store is a good way to familiarize yourself with potential items you can re-purpose in your projects (plus, there are sometimes some cute farm girls there buying chains and clevises). Now, we just released the Perfect Size Crane for your Garage. Available in a variety of sizes and styles to suit every space and specification, we have a variety of sizes and styles to suit every space and specification. I just want everyone to be aware.

Garage gantry crane is a kind of small gantry crane used to facilitate lifting work. We may earn commission if you buy from a link. Access to Tools: The fact that I had easy access to a laser cutter, a CAD Brake, CAD software, a lathe, and some excellent fabrication mentors really gave me flexible design options. Only during final assembly did I realize that the only way to assemble it was on a ladder...holding two pretty heavy parts of the trolley body...trying to simultaneously align four pins in their holes...with a bunch of spacer washers loosely hanging on. Some of the earliest "makers" made this cool gadget for lifting water. OK, MechanicalElements.com has Gantry Crane plans – for years. I earnestly believe that structural engineers earn their keep and while I suspect they mostly use software for most calculations these days, we owe some respect to those who fully understand and engineer safe products which carry loads, especially loads that move (like on trolley's). For instance I would have loved a system that lifted 4000lbs safely...or a system that had an electric trolley travel system....or a system that once out of my garage I could raise telescopically to get another 5' of lift...but if I'd done even just one of those, I would probably have never finished the project. While you may not run into this problem, keep a cool head when these sorts of issues arise on your project. In this Instructable, I'll share how I built a mobile gantry crane to lift things around my garage, lessons learned, and share some general project approaches I used to build this tool. In my case I wanted to still be able to roll the frame over an automobile, so I placed the bracing beam high enough so it should clear most pickup truck beds. Deffinaitly see myself making one in the future. I did that with a MIG welder and an angle grinder. A gantry crane can be useful in your workshop or around your house if you have a need to load and unload heavy equipment from your truck, or move tools in and out of your shop.

I was also able to use the mock up to validate my beam offset measurement of 1". Gantry cranes are typically movable, either on wheels or rails, which make them more useful than a stationary crane or lift. I did email a few suppliers asking for prices on wheels alone, and it was cost prohibitive. You can see in the photo that the pair together of cross members is rated to max load of 4950lbs when the unit shipped new. Seeing everyone's unique and interesting approaches to problems is great, and can inspire others to try their own projec…. Please be EXTREMELY careful in any effort you make around building or operating a lifting device such as a gantry crane. “Gantry crane” means a crane similar to an overhead crane except that the bridge for carrying the trolley or trolleys is rigidly supported on two or more legs running on fixed rails or other runway. I might have paid $100 for the pair, meaning I have about $50 in my main frame structure. Depending on how you source materials, you may choose to design a different structure (such as a "A-Frame" type overhead with a single beam, or some other options). 3 months ago. This content is imported from YouTube. he is too friendly and stronger than he thinks , Fantastic build, and loads of great tips. Thank again for taking the time to make the videos. Nice Project. My approach on this Instructable is less to prescriptively tell you how to build THIS crane, and more to just give Makers like yourselves ideas about how I approached my tool build, so that you as a Maker can formulate your own ideas for your specific tool build. How we test gear. Lesson learned: If you have parts to assembled, it may be best to get 'true dimensions' once assembled for making secondary parts (like the top plate)...or you're probably just better at measuring than I am in which case you may not need to do that! @mwitherspoon....yep....agreed, and thanks for the comments AND for checking out the Instructable. Cardboard or plywood is cheap, and easy to construct mock ups...and seeing the mock up often helps me realize problems early in the process...rather than later when it's too late and costs me money and time.

As such, farm supply stores are more than just cattle feed and shotgun shells. A few comments on his video mention attaching a temporary brace attaching the legs to each other, but that may defeat the purpose of having a crane like this to span an object and have room to maneuver. Sometimes 'cheaper isn't cheaper', so keep safety in mind when sourcing used materials. Point is, if you're trying to do something, often some other human also had that same idea. Also...love the 3d printed weed eater....very cool! Lift Height: Maximizing my peak height for lift, but still being able to move the assembly through my garage doors (which are at 10' in height).
