I-Beam Trolley Plans – 3 Ton, Heavy Duty, DIY

Description

A gantry crane needs a reliable trolley.  If you lift heavy things, this 3-Ton I-Beam Trolley is a strong DIY solution you can build from the plans.

3-Tons is a lot of weight, 6000 lbs to be exact.  We offer Gantry Crane Plans to lift that load, so why not a trolley to match?  If you have looked for Trolleys online, then you know some designs are sketchy.  Not this one – see how we designed it.  We set out with these goals:

1. An overhead I-Beam trolley to carry a true, full 3-Tons.
2. A Trolley you can build (and repair if needed) with mostly off-the-shelf parts.
3. Wheels spread farther apart to distribute load better along the I-Beam flange.
4. Minimize headspace requirements under the beam.

We talk more about these goals in the accordion tabs below.

Yes, you can buy an inexpensive 3-Ton I-Beam trolley online.  That is not the point.  As an engineer I love some things and disliked other things about various trolleys, so I set out to build one better than what I can buy.

In studying available trolleys, I was surprised how weak some designs appear.  Things you want to know, but wish you didn’t.  So, we made one better.  This DIY gantry crane trolley is designed for builders who want a strong, reliable trolley rather than a disposable one.  Plans are available to download right after payment.

3-Ton I-Beam Trolley Key Features

• 3 Ton Trolley (6000 lb) capacity.
• Works with Standard I-Beams from 5″ to 12″.  Not for H, W, or M beam profiles.
• Off-the-shelf rollers and hardware.
• Wide wheel spacing for better beam load distribution.
• Low headroom design.
• No welding required.

Plans include easy to follow, fully illustrated instructions.

This is a perfect accessory for many variations of the Upsized Gantry Crane Plans.  Good luck with your project.

3-Ton I-Beam Trolley To Build From Plans

If you have looked for an I-Beam trolley, then you know there are many options – and some are questionable.  In doing the engineering work on this one, I am even more concerned about the true capacity of the inexpensive trolleys we see online.

For this design I set out to do a few things better than what we can buy.

1. First, design a trolley that will carry 3-Tons.  Not just to advertise a big number, but to actually function under that full load.  (Of course it takes a heavy duty crane to go with it.)
2. Second, make an I-Beam crane trolley to build with mostly off-the-shelf parts.  Things like rollers that can be replaced rather than throwing away the whole trolley if I damage a wheel.
3. Third, my crane has a straight I-Beam, so I do not need a trolley that will turn corners.  I want an I-Beam Trolley that is more stable, with wheels spread farther apart to distribute load better to the I-Beam.  (Read the design study because it is interesting how it turns out.)
4. Finally, I want to minimize headspace used under the beam.  This is a double edged sword – but for me, less headspace requirement is good.  Not to the extreme, but definitely a strong consideration.

If you enjoy building things yourself and want a solid trolley for your gantry crane, these plans will help you build one better than most you can buy.

Construction

Most parts for this 3-Ton I-Beam Trolley are standard off-the-shelf components.  We give McMaster.com part numbers in the plans, but you can also source the parts from a local supplier.  That is what I did to save quite a bit of money on the big bolts.

The 2 side plates and the 2 scuff pads require special cutting.  I chose water jet cutting because the plates I used are hardened 4140, so it would be really hard to cut out by hand.  Water is amazing because it can cut right through the hardened steel.  I sent the included DXF file to my local water jet cutter, along with the hardened plate ordered from McMaster, and they cut-out the plates for me in about a week.

See the YouTube video about building the trolley for more information.  This is a perfect gantry crane enhancement.  Download the plans, then build it yourself.

Construction requires cutting steel tubes and plates.  Welding is not required.
