Note gusset (right) and jack mount(left) welded to the plate and stanchion, The 750 kg lathe safely in the trailer, thanks to the home-made gantry crane, preparing to lift 300kg italian-made mandrel tube bender. Bolt the jacks on each end and remove the locking pins before pumping it up.In the words of the famous car repair manuals: disassembly is the reverse of the assembly procedure. We may earn commission if you buy from a link. Stanchion plate drilled on I-Beam to match. Some more markings with a finer graduation than the locking pin holes, or even a small spirit level on the crane, would make this easier. Making this plate was half an hour well spent and made lifting the lathe much more secure and straightforward. You are not going to be able to stand the crane up without mechanical assistance. The assembly will require some lifting equipment to stand the finished crane upright, and move the parts into place. Brace the top plate with the gusset before full welding to prevent warping. A welded eye close to the centre of gravity took a shackle. Do you have heavy wooden blocks for cribbing in case you need to set down a load to reset the fixing points or shorten a chain? The UB is actually connected at each end to steel stanchions that slide inside the bigger Steel Hollow Section (SHS) end-posts, enabling this beam to be raised and lowered by jacks bolted to the beam at the top and to the outside of the end posts at the bottom.The I-beam takes a mobile trolley and chain block. There are other castors available with a higher load rating and with brakes but the price increases dramatically. Using 90 mm SHS for both the vertical stem and the base cross-bar of the T allows you to fit removable outriggers with screw jacks later if you need stabilising supports or if you want to increase the crane capacity. Gantry crane plans PDF and DWG. If you've got the space and need to move heavy objects around your workshop, then a gantry crane could be your solution. The bottom half of the end-frames is made first. Insert the locking pins. Resist the temptation to suspend the I-beam and remove the ends.

Then I moved the whole assembly as one unit which went without incident.With a lot of machinery, it is hard to find a secure lifting point and the machine can often be top-heavy. Tack the gusset underneath on the long side and the top jack mount on the other side before completing the welds. The one-tonne I-beam trolley was found during a cleanup of the workshop when I was trying to make space just before starting the project, but they are available online for around $170 from various suppliers. The main problem involved how to get the machinery out of the workshop and onto a trailer for the 3½ hours drive to Auckland, then offloaded at the other end. There is a code of practice published by OSH which gives good guidance on rigging and lifting and estimating loads.http://www.osh.govt.nz/order/catalogue/pdf/rigging-ac.pdfThere are some other things to keep in mind for any machinery move. Working the gantry crane by yourself is like being a one-armed paperhanger going from end to end. When doing the drilling in the workshop, manoeuvring 60 kilograms of three-metre long I-beam and holding it up under the big drill press is a bit awkward. If the load starts to swing, it can tip over, or the trolley will come off the beam or the I-beam can twist. Gear-obsessed editors choose every product we review. Good planning is key to a successful move. Or is it beyond the capability of the equipment? In that case, you should get professional machinery movers who make a big move look easy with all the right gear.Gantries like this often have poor sideways stability since you can't cross-brace the frame because the load is in the way.I-beams have relativity poor torsional strength and in addition, the crane with a load can tend to be top-heavy. What steps do you need to do? This will let you put a pin through when the two parts are assembled in the lowest position to lock them together during assembly on site.The top jack mount is a piece of 40 mm SHS with a piece of 40 mm flat on each side to form a square U-shape, with a 16 mm through hole to suit the jack. Try to reduce the centre of gravity by removing milling machine heads or at least dropping them as low as possible.My Colchester Chipmaster has a hole through the bed specifically for lifting, but the lathe I had to move had no designated lifting point. All the construction and moving had to happen over the Christmas holidays. You end up using timber blocks as cribbing to allow you to shorten the chain before lifting some more.The leg could be lifted up higher than allowed by the stroke of the jack, and I may make a bracket that will fit the stanchion pin holes to allow the jack to be relocated to give another 200 mm or so of travel.It is important that the crane is jacked up evenly, which we judged on the number of holes exposed on each side. I preferred a parallel flange beam as it makes bolting the crane together easier and more secure, otherwise you need tapered washers for the mounting bolts.

This unique Gantry Crane maximizes height as noted above, and it also maximizes versatility by incorporating the I-Beam Connector Clamp. This hasn't been an issue in use and having them on the inside would be better design by reducing the span between the lifting points and reducing the overall width.If you don't have the garage door height limitation that drove this design, I would make it taller with a wider base. Bolt the stanchions onto the I-beam—have someone hold them in place so they don't fall over. Using the engine crane, support the end of the hollow section in order to take the weight of the steel under the drill press. I used a tractor as I had one at each end, but an engine crane (if you can get enough height), a chain block and derrick or a shear legs lifting frame would also work. Gantry crane plans with lots of options for height and width. The jack providing the lifting power for the top is a threetonne, long-stroke bottle jack and it’s an alternative means to lift the load without your shed needing extra height for the chain block.The lower parts of the ends of the sliders form an upside-down T shape and the whole is made from 90 x 90 mm structural SHS. The most unusual feature is having these end supports in two parts which telescope together.

To put yourself working under a suspended load is never a good idea.When you are using the gantry crane, you can either fit a chain block to the trolley or use the jacks to jack up the top with the load attached to the trolley or over the I-beam, which is what we generally did.When raising or lowering the jacks, you must operate both simultaneously so that the top assembly remains level. Make your gantry large or small, from Steel or Aluminum, … The swinging load can increase the forces on the gantry to be much higher than the item weight would indicate and potentially could cause it to fail by the beam and leg connection buckling or shearing.For this reason, it is not recommended to move the crane while you have a load suspended. While most rigging and lifting is a matter of care and attention combined with careful planning, when things go wrong when lifting or moving machinery, it can happen very quickly with significant consequences.

Look no further, this is a heavy duty Gantry Crane that can be built in your own garage and will hold up better than those inexpensive Chinese models that all the major stores are carrying now. For a couple of reasons, the welding procedure is very important when the top plate is welded onto the stanchion.• The stanchion needs to remain flat to provide a good fit-up with the beam;• It is very important that it is square so that the loads are transferred straight down.Clamp the plate into position and tack on the long sides of the plate (not across the plate) to the top of the stanchion and check that it is square. The castors I used also have cast iron wheels with grease nipples so they won't develop flat spots or split, which can happen with rubber wheels. They bolt onto the I-beam so use them as a guide for drilling the I-beam flange to match. The crane consists of two, vertical steel end-posts on heavy duty castors with a three-metre long UB (Universal Beam or I-beam) between. Weld on the pre-drilled mounting plates for the castors, making sure they don't warp.You may need to give them a tap with a hammer to flatten them out as they pull on the welds.
