A friend of mine purchased an I-beam and now wishes to make a movable Gantry Crane Hoist that he can use in his shop … and also on job sites.
This is one of those ‘Just for the Fun of It‘ projects I design in SolidWorks while watching TV, so decided to add a challenge to this concept design. To save him money, decided to ONLY use left-over scrap metal found in his storage yard.
While looking to see what left-over metal was available … I found a Mag-Drill which will make drilling all the bolt holes through the metal parts much easier. Yay!! ( It’s the little things in life ) – Electromagnetic Drill
… Also lots of different metal shapes for use in the Hoist CAD Design Concept.
Therefore, the only ‘new’ items purchased are: Bolts, Nuts, Washers, Welding Supplies, Paint, I-beam Trolley, and Wheels. ( At this time, don’t know what wheels we will be using so I put a set of default wheels in drawings )
Noticed he will be using either a 2 Ton or 3 Ton Chain Hoist on the Gantry Crane, so I drew in a I-beam Trolley model similar to the type one can purchase at Harbor Freight … If needed, we can fabricate the I-beam Trolley also.
One feature I don’t like about some other movable hoists is that their Upper Angled Stabilization Supports are under the I-beam; thus, limiting how far the Chain Hoist Trolley can be moved over towards the side stanchion.
For this project, I made the Upper Stabilization Supports mount over the top of the I-beam allowing the Chain Hoist Trolley to slide in-between the I-beam and the Stabilization Supports. Nothing fancy, but sometimes it is nice to be able to slide the Trolley Unit as far as possible out of the way to the side of the Hoist.
This current hoist design is approximately 11 feet from the floor to the bottom of the I-beam. If needed on job sites, we thought it would also be helpful to have the option to raise the height of the sides approximately 2 feet with extensions .
The wheels have 360 degrees of rotation allowing the hoist to be moved anywhere inside the shop. In addition, there are 4 threaded leveling foot pads to secure the hoist in place … Especially on uneven concrete!
We wanted the hoist to be able to be put together by one person with a Forklift or Skid-steer, so we used a lot of smaller parts bolted together in the design.
All main parts are symmetrical allowing their use on either side of Hoist.
During ‘Single Person’ installation… The yellow Inner Side Supports can be mounted below the stanchion sides to act as ‘stands’ to hold sides upright until the I-beam can be lifted and bolted in place. Once the I-beam is secure then the inner yellow supports can be bolted in place.
The hoist will mostly be used in a shop, but if it does have to be moved the entire unit can be unbolted into lighter parts and moved to a job site on a trailer. In most cases – to save time – the sides would stay intact when being transported.
There was a 7 foot I-beam section leftover… If we drill the same hole patterns in this I-beam, then we could also create a shorter hoist for tight places on job sites.
While we could have designed a much sleeker more lightweight design, the goal was just to use the metal we had in the storage yard and have smaller/lighter parts that we can weld in my small workshop and then bolt together on-site.
Hopefully we will be fabricating this hoist in the next few months when the weather cools down … and we have some free time.
