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. I also fitted a removable eye in the centre of the beam for lifting. 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. This content is imported from YouTube. 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. One is the location of the jacks. There are 20 mm holes through both the external slider and the internal stanchion to allow for pins if required once the height has been set. 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. In sheds all around the country, many motors have been pulled out of cars over the years with a chain block suspended from the wooden rafters. The weight was too much for tractors.The solution was a “portable” gantry crane that could be taken up north in parts, assembled on site, be low enough to fit through the roller door but could be raised inside to an adequate height to lift the machinery onto the trailer. 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. The assembly will require some lifting equipment to stand the finished crane upright, and move the parts into place. Stand the crane upright by lifting the I-beam up with your engine crane. • to allow for the wall thickness of the slider tube in the hole spacing; and• that the jack mount is centred across the tube.Check that everything moves freely and is in line before welding it fully. This machinery included a lathe weighing around 750 kg. Using the engine crane, support the end of the hollow section in order to take the weight of the steel under the drill press. Insert the locking pins. Good planning is key to a successful move. I used a level and the trailer jockey wheel to get the beam located square to the drill.Other alternatives would be a large pistol or D-handle drill and cutting oil, renting a magnetic-base drill or using a small drill press clamped to the beam flange as a poor man's mag drill. Frank mentions that he's not a structural engineer, but as a DIYer he wanted to build a solution for moving machinery. 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. Making this plate was half an hour well spent and made lifting the lathe much more secure and straightforward. A welded eye close to the centre of gravity took a shackle. 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. Gantry cranes are typically movable, either on wheels or rails, which make them more useful than a stationary crane or lift. The top plate bolts the sliding stanchion to the I-Beam, Geoff bolts beam and sliding stanchion (upside-down) together. Drill the pin hole first and weld the base to the upright, making sure it is dead square.

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.

Plans include lots of information with graphs and charts showing engineering options. Resist the temptation to suspend the I-beam and remove the ends. The most unusual feature is having these end supports in two parts which telescope together. This size allows the 75 x 75 mm SHS stanchion to slide inside with a minimum amount of slop. 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. If you weld the top plate fully before bracing it with the gussets and the top jack mount, it will warp and bow downwards when you weld across the plate.Assemble the two parts and make sure the stanchion is fully seated in the slider and that the locking pin holes line up. Easily fabricate this Gantry Crane yourself and save money while doing so. 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. All the construction and moving had to happen over the Christmas holidays. The bottom half of the end-frames is made first. There are other castors available with a higher load rating and with brakes but the price increases dramatically. 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. 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. I used my trailer as a trolley and noticed that the top of the I-beam was a similar height to the table, so moved the table out of the way and rolled the trailer into place.

Tack the gusset underneath on the long side and the top jack mount on the other side before completing the welds. 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. But that wasn't going to do it this time. Vestil AHA-4-8-10 Aluminum Adjustable Gantry Crane, 4000 lb. Pride of … Do you have enough chain, rope, slings and shackles?
