I welded the top plate of the caster wheels to the lower plate of the pallet rack frame. Garage Storage. Even just looking at the Shadoof image might make you think about using counterweights to offset lifting effort, etc...so make sure you look around at previous work others have done in making tools like what you're looking to build. 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. 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. 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!) I just want everyone to be aware. But when they're sized down to more … “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. You need to build a welding table and the table top alone weighs enough to break 4 helpers’ backs at the same time. Ideal for both storage or your next DIY project, a workshop or garage can be utilised in a range of different ways. 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. Explore. Gantry Geometry: Regardless of the material you choose to build the gantry beams from, the geometry is an important factor in the strength of the construction. If you are doing a build like this I'd encourage you to do small re-checks on such things. I suspect this is not the preferred or advised method for making the beam to chain fall attachment (since the box the chain was in said "not for overhead lifting"). I appreciate the kind comments, and you have a pretty impressive I-bles list yourself! 2 LITERATURE REVIEW LK Goodwin CO. is a material handling equipment company that sells many types of hoist’s and cranes for certain applications. You may be able to find more information about this and similar content at piano.io, Tool Gift Guide: 36 Great Presents for DIYers, 25 Last-Minute Gifts and Stocking Stuffers. Sometimes 'cheaper isn't cheaper', so keep safety in mind when sourcing used materials. good luck with ur projects! Aug 23, 2014 - Build an overhead hoist with these old but good portable gantry crane plans and drawings. Reply You'll probably learn something and it may help you identify safety issues that may not seem apparent. Man....talk about crafty, those folks couldn't even google it...so imagine trying to come up with that thing on your own! @seamster - you had me at 'sewing machine tractor' ! 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. About: I believe places like the Instructables community are important for encouraging others. - The facility where I used the laser cutter is a small business incubator which specializes in helping small businesses in manufacturing to be better equipped to utilize modern CNC/manufacturing techniques. Industrial Office Store Closing Auction: A local big box office supply store was going out of business. Once the cross beam was set, I went back and checked every bolt. 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. 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. I built it with a combination of used components and some laser cut steel to make a useful overhead crane I can roll around my garage and use to lift large and awkward things like truck beds or such, with no help required. I did NOT however, change the diameter of the pins. 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 … 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. 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). 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. Whatever tool you are building, its important you consider what you will really do with the tool and what considerations come into play as requirements. Sourced Materials: The dimensions and unique structure dictated by the used pallet shelving superstructure defined my design in many ways. 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. After everything was assembled, I needed an actual way to lift things from my newly set cross beam. You can buy a gantry crane for $500 to $3,000—or build one yourself like Frank Howarth did in the video above. 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. This is known as ‘permitted development rights’. 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. 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. 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. 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. Those final CAD drawings only came after a LOT of pencil doodles, and plywood mock ups. YOU, MY FRIEND, NEED A GANTRY CRANE!!! Adding Caster Wheels: I wanted the crane to be able to 'roll around'. After some shopping I choose solid caster wheels (600lb load rating per wheel) which had a grease fitting and a flat top mounting plate. Discover (and save!) 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. your own Pins on Pinterest Are you tired of all the work and the funny noises your back keeps making when you are lifting things? It's good to be creative and explore alternatives places to get materials. Thanks again for checking it out! 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. what is available to build a gantry hoist. 20. 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. Thanks for sharing your process. It might just save you some time (and your sanity). 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. Point Loads, Static Loads, Engineering Degrees and such: I learned that no amount of YouTube or Googling is a substitute for formal education in understanding point loads...and further point loads that move and their effect on structures. rennaker331 says: January 27, 2019 at 9:12 pm I love your videos. 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. I measured my pin diameters and left just under 1/16" of clearance when I set my pin hole diameters. You have a wealth of knowledge now. I wanted to come in well under that number, and was willing to give up some time to do it. The laser cutter certainly made it much more realistic for me to make the trolley bodies more complex. ...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). ;-). While you may not run into this problem, keep a cool head when these sorts of issues arise on your project. I bought my chain and chain links at a local farm store. - The motor in the last photo (hanging from the hoist) is a 4.8L small block Chevy fully dressed. 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). Seeing everyone's unique and interesting approaches to problems is great, and can inspire others to try their own projec…. 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. Designing any lifting system is inherently dangerous. 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. Hey...thanks for the compliments and checking out the build. They helped me take my CAD file and correct mistakes, and get it ready for the laser cutter as G-Code. OK, MechanicalElements.com has Gantry Crane plans – for years. Tags: Chain, Gantry, Garage, Hoist; Categories: DIY garage projects; Comments. That...was a bad idea. Tip the assembly over on an angle and slide on the bases until they are fully seated. I had a lot of assistance from some great guys at the local manufacturing business incubator where I rented time on their laser. Point is, if you're trying to do something, often some other human also had that same idea. I have to say here, I made about 8 steel coasters for my garage in doing this. 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. Prepping the Cross Beam: I happened to have a 4" I-beam laying around so I shortened it in the band saw, and drilled two holes in each end to match the mounting holes I had cut in the trolley top plates. thanks for all the valid points, and raising them...as well as the very nice comments! 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). 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. 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. 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. It’s easy to use, easy to adjust, and easy to disassemble for storage or portability. To make my overall superstructure, I re-used a commercially manufactured pallet shelving structure I bought used from a major 'big box' office supply store. Mobility: I wanted my crane to roll around and be mobile. What a great idea. 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. Whew, that's a lot of boxes of paper reams! 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. Top Plate Beam Seat: Once I had the mock up I was able to rough out the dimensions of the top plate beam seat. Garage gantry crane is a kind of small gantry crane used to facilitate lifting work. . https://upload.wikimedia.org/wikipedia/commons/4/4... How to Make Charcuterie Boards Using Clear Acrylic Templates. Dec 20, 2015 - This Pin was discovered by Craig Mason. Frank mentions that he's not a structural engineer, but as a DIYer he wanted to build a solution for moving machinery. 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. One unique thing that arose in my case was the pins I scavenged from my Ebay purchased trolleys were "too wide" for my beam. Some Oddball Notes from the project that might interest a few: - I pulled the specs for the pallet rack from the manufacturer's website. Before this project, I wasn't sure I could plan and layout a set of components on a laser cutter which would fit together properly. @mwitherspoon....yep....agreed, and thanks for the comments AND for checking out the Instructable. 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 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. I'm not sure what a new pallet shelving system costs, but I'm guessing it's more than the $50 I paid. Saved from practicalmachinist.com. he is too friendly and stronger than he thinks , Fantastic build, and loads of great tips. While you may source different parts requiring differing approaches, hopefully this Instructable encourages others to get out there and build stuff. I attached the chain fall hoist to the cross beam using chain rated to 5400lbs, and used 6600lb rated links to connect the ends of the chain to each other to make a loop. While those things are "cool", this system covers probably 90% of the needs I have. If I'm reading it right the entire rack as a whole is rated to a max load of 28,000lbs. I watched a video over a year ago and have been hooked since then. The brake was a CAD brake which helps you by calculating how much the metal will stretch, and how much the bend radius changes your geometry and a little 'robot arm' of sorts helps you set the bend point. Nice Project. Storage And Organization. Looking through their list of portable hoists, a 2 ton has a cost Additionally, in shortening it, that forced me to cut out and weld back in one of he angled struts on each frame. Gain some head room by fabricating a small beam clamp and losing the chain. 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. 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. Trying Something New: I think the Instructables community is about encouraging others to try something new they might otherwise not feel capable of. 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. Gantry crane plans telescoping design basic a frame gantry crane 13 practical machinist largest Diy Garage Jib Crane - Gantry Crane Plans With Lots Of Diy Options To Make It Perfect « Home Gantry cranes are those large structures you see in shipyards that are used to unload shipping containers. I have found that doing rough pencil sketches initially, before committing to anything more firm saves me time and hassles. I might have paid $100 for the pair, meaning I have about $50 in my main frame structure. 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. 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.
