They can fix anything. Garage gantry crane is a kind of small gantry crane used to facilitate lifting work. As long as you don't plan on liftling a whole car it should be totally fine. 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? I like using mock ups of cardboard or wood for things that will eventually be 'made real' in steel. Home Decor. . and you "just need them to run over and help you lift something..it won't take 10 minutes, but they end up there for 3 hours? Once the cross beam was set, I went back and checked every bolt. I'm not sure what a new pallet shelving system costs, but I'm guessing it's more than the $50 I paid. I also happen to have a steel plant a few miles from my house that's friendly to individual buyers for what new material I had to buy. Love it.I just want to add a bit to your well emphasized safety concerns:- the load rating of the stringers is probably based on an evenly spaced load, not a concentrated load at the middle of the beam, so reduce the number by a lot. Ideal for both storage or your next DIY project, a workshop or garage can be utilised in a range of different ways. What a great idea. your own Pins on Pinterest I have to say here, I made about 8 steel coasters for my garage in doing this. Additionally, in shortening it, that forced me to cut out and weld back in one of he angled struts on each frame. I was also able to use the mock up to validate my beam offset measurement of 1". Mobility: I wanted my crane to roll around and be mobile. 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. So before you begin, it's a good idea to go through your materials list and at least put some ballpark prices beside each item. 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. Even factory produced units can fail causing injury or death. The alternative choice would be to completely start from scratch and custom build one on your own. Brilliant idea, cheap and effective.I think it'll be plenty solid enough for lifting an big engine. - The motor in the last photo (hanging from the hoist) is a 4.8L small block Chevy fully dressed. Discover (and save!) 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). Point is, if you're trying to do something, often some other human also had that same idea. Gain some head room by fabricating a small beam clamp and losing the chain. About: I believe places like the Instructables community are important for encouraging others. You start thinking of all the possibilities that having your own Gantry Crane would create but it is too expensive to … Recent Posts. Sometimes 'cheaper isn't cheaper', so keep safety in mind when sourcing used materials. Mechanic Garage. 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. Now, we just released the Perfect Size Crane for your Garage. Availability of materials and how you source them can impact and dictate overall design...and it did for me. : So the black and white photo I pulled and placed in this step is very cool. The only thing you will need to do after that is to put the pieces together as instructed. If you get a chance, hug a structural engineer today and thank them for making sure we all don't end up with heavy things coming down on our heads! I placed one lower in the rack to act as a brace, to reduce tendency of frame to 'spread' under load. Find great local deals on Sale diy for sale in Widnes, Cheshire Shop hassle-free with Gumtree, your local buying & selling community. 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. While tools like CAD, SOLIDWORKS, Google SketchUp, and Blender can can feel 'fancy', sometimes a pencil and an eraser are the easiest way to work out ideas in the early stages. 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. I debated if I should put at least small tack welds on where the horizontal beams where those retainers are to further prevent any upward movement, but decided not to so that I retain the option of completely disassembling the superstructure for transport if necessary. While I did make a pair using my mock up dimensions, I ultimately ended up making another set later as my plywood mock up flexed and to make more precisely fitting top plates, I measured the steel trolley bodies once assembled, and then cut/broke new ones which fit with closer tolerances. 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. It's best to call ahead, and while I did not use this option (but I have on other projects) this is a cheap way to score raw materials for builds, and def worth checking out. On my gantry crane, this certainly ended up being the case. OK, MechanicalElements.com has Gantry Crane plans – for years. Bridges do fall down.- load test the machine with ever increasing weights in every position over every anticipated terrain until it fails, then divide the minimum weight at which it failed by three or four to give you a safety factor and a safe working load. Yes, our ram can be a pain in the bum sometimes. Man....talk about crafty, those folks couldn't even google it...so imagine trying to come up with that thing on your own! 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. In my case, my pallet rack uses a hollow tube beam on which the wheels ride. I found I'd left two loose somewhere in the assembly process, and I'm very glad I checked. ; and, it’s great for lots of other lifting chores. and see how THEY solved the problem. As such, farm supply stores are more than just cattle feed and shotgun shells. 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). While you may not run into this problem, keep a cool head when these sorts of issues arise on your project. 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. My main hope with this Instructable is it encourages at least one person to stretch past their comfort zone when it comes to being a Maker, and that you try something new that feels just beyond your current capability. This system was designed years ago, and many have been built (in various sizes) over the years. While searching for ideas for my gantry crane, I learned about the "shadoof". 3 months ago. I used TurboCAD to create a file for use on a laser cutter. At the risk of harsh criticism within the New York and Milan art communities, I'm sharing a couple of my early sketches...while very far from perfect, just sitting around doodling these rough sketches got my brain thinking about the problems I might run into with various designs...don't be afraid to tinker with a pencil. Top Plate Beam Seat: Once I had the mock up I was able to rough out the dimensions of the top plate beam seat. Hey...thanks for the compliments and checking out the build. Thanks again for checking it out! Nice Project. Some Oddball Notes from the project that might interest a few: - I pulled the specs for the pallet rack from the manufacturer's website. Bought not Built: Honestly, if I had to advise anyone or do this over again, I'd just suggest you buy a commercially produced overhead lifting system. Preferably anchored to the floor to prevent splaying [and tipping], otherwise relying on friction of the legs on the floor to prevent spaying. Loads which are moving either on trolleys (like I built here) or on casters (like on the feet of the rig here) totally change the situation vs say a system that is permanently installed in a fixed position. I wanted to come in well under that number, and was willing to give up some time to do it. Once you get close to what you think your final design is on paper, then you can (if you wish) move to something on a PC like Google SketchUp or such. Jan 19, 2016 - Homemade gantry crane constructed from 2x6s, 2x4s, threaded rod, pipe, casters, steel strap, and an electric hoist. I had to be very careful here that the drilled I cut in the beam were spaced exactly the same distance from center to center on the trolley bodies. Aug 23, 2014 - Build an overhead hoist with these old but good portable gantry crane plans and drawings. I did that with a MIG welder and an angle grinder. Metal Recyclers/Junkyards: Some junkyards sort materials and will allow you to 'come browse' for things you need. It's a Federally funded facility, but I still pay for rental time for use of the laser table. You have a wealth of knowledge now. As a professional gantry crane manufacturer in China, Aimix provides and customizes various gantry cranes according to customers’ requirements, like portable gantry crane, adjustable gantry crane, light duty and heavy duty gantry crane, truss gantry crane … Adding Caster Wheels: I wanted the crane to be able to 'roll around'. So thanks to you for doing that! 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. I welded the top plate of the caster wheels to the lower plate of the pallet rack frame. Garage Storage. Local Farm Stores: Don't forget...some of the craftiest people anywhere are farmers. ".....Do you need to take the bed off your truck so you can undercoat because they clearly undercoat cars at the factory with rust, and you just can't find anyone to help? Just remember, going "cheap" isn't prob smart on something holding a ton of material in the air...so finding out your chain hoist is made of smelted peanut butter and tin, and not actual steel...well, you don't wanna find that out with something heavy hanging on that peanut butter chain above your head. Jul 17, 2017 - REID Lifting's PORTA-GANTRY RAPIDE can carry up to 500kg and is fully certified to European & North American standards for both goods and man-ride use. If you are sourcing material for a hoist or crane by using "upcycled" materials, its a good way to save money, but a builder should consider what sort of fatigue and abuse the re-used materials have seen in the past, and if they might be prone to failure due to reduced working load/etc. 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! 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. Storage And Organization. Once assembled, I was able to see possible issues with my design that I had not realized when sketching up the bodies on paper. One unique thing that arose in my case was the pins I scavenged from my Ebay purchased trolleys were "too wide" for my beam. 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). In my case, considerations I had to make in going from mock up to final drawings for the trolley bodies included: Horizontal distance between wheels: I chose to space my wheels at a pretty wide span to distribute load. 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. So, my starting point and build was largely dictated by materials and tools I could source cheaply and nearby, and material/tools I had on hand. Designing any lifting system is inherently dangerous. Homemade Wooden Hoist. Dec 20, 2015 - This Pin was discovered by Craig Mason. I ended up buying a new chain fall type hoist. So I was forced to make my inner wheels on the trolley sit 1" lower than the outer wheels. Personally, I use a tool called TurboCAD, which works fine for my purposes....but some of the best fabricators I've ever met never touch a computer...it's all pencils, soapstone chalk, and some supercomputer in their head fueled by MIG welder flux fumes and donuts. Yah...I was able to lift cast iron V8 engines without any issues...I'll leave the whole car lifts to the hydraulic jacks! 20. 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!) ...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). 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. I went there during the last days of the auction/sale and bought two pallet shelving systems. if you notice the photo, early on I had two very large chain loops around the beam, and then realized I needed to choke it up and gained a solid 12" of height or so just from that...so your advice on the beam clamp would prob gain me another 6" or more easy...thanks for the idea and for checking out the Instructable! I bought a 1 ton only because I may need to use it elsewhere, but I never intend to lift more than around 800lbs on this crane. Gear-obsessed editors choose every product we review. Thinking About Assembling the Tool: In all my drawing and making on this project, I had never even stopped to think about "how will I assemble this?". Gantry cranes are those large structures you see in shipyards that are used to unload shipping containers. @seamster - you had me at 'sewing machine tractor' ! Consider what you are 'trying to do' and be realistic. Reply While those things are "cool", this system covers probably 90% of the needs I have. Once I had the chain loops around the beam, I hung the chain fall hoist from it, and at that point, I had a working gantry crane. But when they're sized down to more manageable proportions, the same mechanical principle can be applied to moving heavy objects in a workshop or even your home. I felt that doing a wider span might help a little with distributing the load from a 'single point' (I'm very specifically avoiding terms like "point load" here as that is not my expertise, and you should consult an engineer for any real conversation on that topic). 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. 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. This way, if I moved and wanted to place the trolley as and individual units on an overhead beam (such as those built into some garage ceilings), the tools would be portable in that sense. https://upload.wikimedia.org/wikipedia/commons/4/4... How to Make Charcuterie Boards Using Clear Acrylic Templates. 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. I think a challenge for all Makers is running into issues like this, and letting it stop a project. Mar 2, 2015 - Hey guys and gals, Just thought I would share where I'm at on my gantry crane build. In any event, I simply took measurements of the offset and incorporated that into my final measurements. 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. Explore. 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. Once I cut the beam to length (the width of from the outer side of each trolley body) and drilled the mounting holes, I bolted on the trolley top plates onto the beam. I did NOT however, change the diameter of the pins. 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. While you may source different parts requiring differing approaches, hopefully this Instructable encourages others to get out there and build stuff. - 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. If I'm reading it right the entire rack as a whole is rated to a max load of 28,000lbs. thanks again. The frame works delightfully well for that, as well as loading stuff out of pickup beds. Bolt the stanchions onto the I-beam—have someone hold them in place so they don't fall over.

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). SAFETY WARNING: In an abundance of caution, I'd reiterate and point back to the safety warning I put in step 1. After some shopping I choose solid caster wheels (600lb load rating per wheel) which had a grease fitting and a flat top mounting plate. Seeing everyone's unique and interesting approaches to problems is great, and can inspire others to try their own projec…. You may be able to find the same content in another format, or you may be able to find more information, at their web site. 3 months ago 2 Ton Mobile Gantry Crane Let’s face it. The internet is so full of really cool projects, I'm thankful if anyone even reads this Instructable.

You can buy a gantry crane for $500 to $3,000—or build one yourself like Frank Howarth did in the video above. 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. They helped me take my CAD file and correct mistakes, and get it ready for the laser cutter as G-Code. These retainers are simply little steel flat springs you push into place. It might just save you some time (and your sanity). SAFETY DISCLAIMER: Fabrication and subsequent operation of lifting devices such as overhead cranes, hoists, jacks, etc, are inherently dangerous. Thank again for taking the time to make the videos. Some of the earliest "makers" made this cool gadget for lifting water. I ordered raw plate material from my local steel supplier (mild cold rolled), and simply load the plate on the laser, and let it take the G-Code it generated from my CAD file, and it does the rest. Sometimes parts sourced by scavenging or re-purposing on a project can introduce their own problems, and require modification to suite your purpose. I have found that doing rough pencil sketches initially, before committing to anything more firm saves me time and hassles. I hope this is the correct area to post this (Mods, please move i. 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.
