Movable Gantry Crane Hoist

Hoist-02

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.

— CHEERS…

    You Gantry crane is just what I was looking for! Thanks for sharing it on GrabCAD. is Did you upload the IGES file for the chain hoist? I would like to incorporate it in my design.

    Thanks, Jesse

    • I will add a IGES version of the Chain Hoist, if someone hasn’t already added one. It is just a ‘Visual’ design and not a working CAD model, but it will work for rendering purposed if that is what you need. CHEERS!!

    Thank you very much for sharing your work.

  3. do you have all the measurements for the crane I love the design. Thanks Phillip

  4. Excellent design and thanks for sharing it here. I got very helpful information from your post.

    • Thank you for the nice comment 🙂 This is a link to the Gantry Crane Hoist Design we ended up making https://ctmprojectsblog.wordpress.com/2015/07/02/adjustable-height-gantry-hoist/
      🙂
      The design allows for the Hoist to be unbolted and put on a trailer with a Skid Steer in about 30 minutes and transported to different job-sites for use on-site for weeks at a time … Pretty much need a skid steer to assemble it on site, but only takes two guys 🙂
      The hand-pump hydraulics were inexpensive low-tech way for one guy to raise and lower the Hoist from the lowest position to the highest. Made a one (large bolt) ‘quick connect’ that allows the hydraulic rams shaft end to be reset to then raise as many times as needed. A bit slow with one guy walking back and forth to each side but it works; however, with 2 guys it takes about 5 minutes to raise or lower i-beam and the boltd/pins are secured when at the height wanted so the hydraulic rams can them be removed if we wish. 🙂 We didn’t want to leave expensive hydraulics at job-sites, so these are just inexpensive Harbor Freight Tools hand pump 3 Ton rams and they work on other equipment if needed. CHEERS!!!
