This video from 2014 showcases a Simmons automated production wheel press in a heavy haul railway wheel set maintenance facility. The wheel press machine cell contains a Simmons SMP-200 200-Ton Pre-Mount and Mount Press plus a variety of automated material handling systems. It pre-mounts and then mounts a wheel set after whatever relevant operations have taken place elsewhere in the maintenance facility (measurement, wheel reprofiling, wheel boring, axle reclaiming). Once mounted, the wheel set will be transferred to the bearing mount machine cell.

I hope we get like this machine in our wheel shop asap , I still use the manual machine
It is quite the machine! Drop me a line at jmurphy@smtgroup.com, and I can help make that a reality. What machine are you using in your shop now?
Crane Global Sales.
Ha, you are out of work then
@@nsh-usa sogema 😞
@@عبداللهالروسي-ح5ب Well, if you folks are looking for new machines, I hope you will keep us in mind. Thanks!
The wheel and axle shop I worked in was that clean , oil and grease free only once fifty years ago. Well done .
Thanks! The folks are this shop take great care of it.
Fun to watch.
I'm amazed that the wheels aren't first heated before pressing onto the axle. I thought that would be needed for a proper fit.
Pressing with heat was how it was done during the steam locomotive days - hydraulic presses are the name of the game these days.
That's for tyres not wheels
Simmons-Awesome job here! Almost crushed my finger 8 times or so on the manual machines
That's the name of the game, Luke - safety! Thanks for watching.
The wheel press here exerts 40,000-50,000# of pressure to press the wheels on the axles. There is a .003" difference between the axle and wheel.
Hi Robert - the press can apply up to 200 tons of pressure in the mount press section. And yeah, that interference fit is something. Thanks for the comment!
Wow! Here the wheels were mounted on, by warming .Now technology goes forward....
Based on comments on this video, it does seem like that practice is still used. However, here in North America, the standard is using a press to mount and/or demount the wheels. Thanks for watching!
Jeez man the force used to press these wheels....well put it this way you wouldn't want to get caught in between them
200 tons of pressure on the mount press! Yeah, stay clear. Thanks for watching!
Just uploaded to Simmons' TH-cam channel is a video of an automated railway wheel mount machine cell in action. The cell is part of a customer's heavy haul railroad wheel shop. Give it a gander! #railway #railroad #automation
I was expecting much more details in how the wheel is mounted ... BTW, what about the extra rod after mounting? All in all rather a slapstick job ...
Hi Cornelius - if you are looking for more information on the mounting process, I recommend checking out our most recent press video: th-cam.com/video/ZnnY-VkUqVM/w-d-xo.html. As for the extra rod, I'm not sure what you are referring to. Thanks for watching!
That is so cool, thanks for posting.
Thanks for watching, Bob!
Which lubricant use for pressing?
We recommend using WM-10 for all wheel mounting. Thanks for watching!
Thanks for the reply!
I admit, to some ignorance but there seem to be a lot of movements and operations here.
Hi John - while I cannot speak to the totality of this process, I do know that this system has been redesigned for a faster cycle time. Here's hoping I can get some video of the new system in action later this year so you can give it a gander. Thanks!
Hmmmm, could be
Back in the old days two old guys would just push the wheels on
This way seems safer - not just for the two old guys, but also the people and/or freight that are riding on those assembled wheel sets.
why isn't the wheel seat and the inside of the wheel lubricated?? I work in a wheel shop and according to the G2 by the aar. the entire inside of the wheel and half the wheel seat should be lubricated
+john hilton Hi John - while the lubrication process is not shown in this video, you can see the wheel bore lubrication in that same shop here: th-cam.com/video/Mg7tqPkcgAI/w-d-xo.htmlm24s. The wheel seat and bearing journals are lubricated elsewhere in the shop. Thanks for the question!
If you watch when the 2nd wheel is pressed on, close up, you can see some lubricant being pushed out of the wheel-axle connecton.
Since I didn't see them being lubricated, I was watching for smoke from the friction of the pressing.
Simmons Machine Tool Corporation why they don't used melcot
Hey John. I would like to know how many tons do you need to press a wheel set. Thanks
Hi Diego - this press maxes out at 200 tons of press force. We have other presses that go all the way up to 600 tons. Thanks for watching!
What does a single wheel set like this weigh?
Hi Rick - it all depends. We usually give a range of 500 - 1800 lbs. (227 - 816 kg). Thanks for watching!
This is a fantastic
Agreed! If you get a chance, check out the recent video that shows off the updates to this cell: th-cam.com/video/ZnnY-VkUqVM/w-d-xo.html
Loved running 38s on a manual press,seeing only the wheel being oiled gave me anxeity though 😅
Both the wheel bore and axle wheel seat are lubricated upstream from the press. Sorry to get your heart racing!
@@nsh-usa ahh gotcha,we used a blue oil so you could see it lol
Bei dem Tempo erklärt Das natürlich, warum die Bahn immer Verspätung hat ...
Gibt's diese Maschine auch in 'zumindest ein ganz klein Wenig schnell'?
Hallo AAAO OAAO - An dieser Maschinenzelle wurden zahlreiche Änderungen vorgenommen, um den gesamten Prozess zu beschleunigen. Schau es dir an: th-cam.com/video/ZnnY-VkUqVM/w-d-xo.html
Fantastic
Thanks for the kind words! And thanks for watching.
Wow that took a long time until the wheel was there. The axle already started rusting
Hi Gummel - we keep updating our automation offerings + capabilities, so we are always working to cut cycle time while still moving wheel set components safely + efficiently. Thanks for watching!
Gummel Intresting but what you don't see is people, they need jobs.
Hi Donnie - it's worth noting that many of these videos (this one included) are shot in active customer facilities that, for a variety of reasons, do not want their employees in our videos. I can assure you that this facility has employees that operate and maintain these machines. Thanks for watching!
Simmons Machine Tool Corporation Thank you for your response, it's very interesting to see how their put together to support that massive tonnage, if my figures are correct I think just one weighs about 15,000pds is that correct ?
Are you talking about the press itself or a wheel set? This version of the press weighs 24000 lbs. (10887 kg); whereas a standard gauge wheel set with 38” (965 mm) wheels weighs about ~3000 lbs. (1361 kg). Let me know I am missing the point...
Great video 'cept for the music if you want to call it that. I had to mute.
We've been waiting for your remix, Shania! Thanks for watching.
So how did you decide what kind of background music to use to encourage engineering type people to watch your video?
Did you consider engineering type noises... like the machinery itself?
Hi Peter - my preference is always machine + facility sounds, but it was not possible in this video for a multitude of reasons. If you check out some of our newer videos, I think you will "hear" what you are looking for - for example: th-cam.com/video/ZnnY-VkUqVM/w-d-xo.html. Thanks for watching!
Is thermal expansion and fitting not followed any more?
The Association of American Railroads (AAR) recommends mounting wheel sets within a specific range of tons-force, so our presses are designed with that in mind. Thanks for checking out the video!
Can u tell me how much tons of load applied?
200 tons is the max pressing force on this press - we sell other presses that go up to 600 tons of force. Thanks for watching!
Where is this factory located?
This is FMG in Port Hedland, Western Australia. It's quite the facility!
Sure is! I’ve worked there for 5 years now. Amazing facility
@@jakewyatt716 Glad to hear the shop is still treating you well, Jake!
Can I order this machine in India ?
Hi Laxmi - you can indeed! Please send us more information about your facility's needs to sales@smtgroup.com, and we will go from there. Thanks for your interest!
So how it's made basically
Works for me! Thanks for watching.
I like this
Thanks for the kind words! It's quite the machine + video.
What is the OD of the axle where the wheel rides and ID of bore on wheel?
Hi jockellis - let me run down that information for you. Thanks for checking out the video!
Got the answer from a colleague here at Simmons! "For these class G wheel sets, the raw axle is 248 mm in diameter and the raw wheel has an ID of 238 mm; once the axle is cut (to achieve taper and surface finish), the wheel is bored to match."
Simmons Machine Tool Corporation Thanks. So it is definitely a Press fit?
It is indeed - you can see the graph started at 02:37.
That's one large barbell.
Get those reps in! Thanks for watching.
very good job
Thanks a ton!
Do these wheels work good on snow and ice? Lol
Hi Brian - we can only do so much, right? That being said, railways are all working to deal with weather and other detrimental conditions, so here's hoping. Thanks for watching!
Is it press fit with how much load and what is the size of shaft OD & wheel ID ?
Hi Subham - the mount press in this system has a maximum pressing force of 200 ton. I'm not certain of the wheel plus axle wheel seat dimensions specific to the wheel set in the video - I do know that we can accommodate a wide range of wheel set types. Thanks for watching!
@@nsh-usa Neat stuff! Having an engineering background (retired), I would have liked a *focused* video on the operator's readout screen (ref 2:37-2:47). It appears that force is plotted against wheel displacement along shaft with the force axis being vertical. So when wheel is pressed into place, and no longer moves, the graph becomes a vertical line. It would have additionally been informative to read graph, size of nos. on each axis, etc. I presume the green and red vertical lines are 'go' and 'no go = max' force limits.
@@wordcarr8750 Hi Word Carr - I went straight to the Mechanical Engineer Stephen Zavos who helped design this and the rest of our presses: "The graph is showing the force vs. displacement, but the displacement is the vertical axis and the distance is the horizontal axis in this case. This customer had requested the axis shown in that orientation. These particular wheels are not seated against a shoulder and are mounted to a set position. The green line represents the minimum allowable pressing force and the red line is the maximum allowable pressing force. An AAR Template can also be placed on the screen to ensure it complies with those rules as well if needed. Typical mounting force for these wheels is around 150 to 200 tons." Hope that help! Thanks for watching, and let me know if you have any additional questions.
@@nsh-usa: Thanks for your response. Just a further (nit pick) point re: graph naming (as I also taught school). Graphs are named, if basically just X vs Y, with the VERTICAL axis quantity named FIRST. So, if the vertical axis showed DISPLACEMENT (by customer request) then the graph would be called: DISPLACEMENT vs FORCE.
That's a reasonable comment, Jim - thanks for pointing it out!
Awisome
Seconded! Thanks for the comment.
'
how about two strong alloy aluminum wheels with one steel rod'''
light weight than heavy weight
We don't make the wheels, we just press 'em. However, I wonder if that set-up would support the heavy axle load of this shop. Those wheel sets are moving iron ore, with the axle loads at 40 tons being one of the heaviest (if not the heaviest) in the world. Thanks for checking out the video!
Two problems:
Aluminum wheels would begin to deteriorate immediately under the heavy loads applied to them;
Aluminum / steel contact can result in galvanic corrosion, a problem railroads encountered when they first tried mating aluminum car bodies with steel frames.
When AAR expects 3 misfits every 1000 wheel pair🤣 at the same time automated wheel press's are crucial these days
Less misfits AND increased safety? We are in. Thanks for watching, Cedric.
Thats pretty cool but....
I see alot of unnecessary steps and too much automation... This line is inefficient....
Noted! It's worth mentioning that the next iteration of this press + automation is currently being built, so we will keep you updated. Thanks for checking out the video!
Defect! The wheels are rusty. Customer sends it back.
I'm fairly certain that is not the case, as these wheels will have bearings mounted and then the finished wheel set will be put into production.
LOL. Seeing how it’s super thick heavy steel that would take forever to rust through. You’re joking 🙃 right???
Almost all the wheels i ran were rusty unless they were new turns or foreign wheels
😍😍😍😍😍😍😍😍😍😍
Agreed! Thanks for watching.
One wheel weight
It's a range, but we use 500 - 1800 lbs. (227 - 816 kg) internally for a single wheel weight. Thanks for watching!
This is way-cool.
Just imagine showing this to "cave men". Lol
I am sure they would be knocked out! Thanks for watching, Brian.
👍👍👍🇷🇺
Спасибо за просмотр! Я надеюсь, что вы здоровы и в безопасности.

Люблю технику !
И вам удачи ! 👍
Спасибо за добрые слова - и спасибо за просмотр! Лучшего здоровья и безопасности для вас.
My Harbor Freight press could do that faster. Just in case though, I will get the extended warranty.
Hi Matt - I'm not certain your Harbor Freight can hit the required 200 ton mounting force. If it can, I want to see that. On that note - this video has been updated: th-cam.com/video/ZnnY-VkUqVM/w-d-xo.html. Thanks for watching!
Shoot. just use the AutoZone tool rental.
@@nsh-usa I am a Manufacturing Engineer, I can appreciate the process. Thanks for loading the video!
I don't know if that would be AAR-approved - I do appreciate your thriftiness, though.
Thanks for watching, Matt!
О, ВКМ 😏
Thanks?
Beep beep
And a "beep, beep" right back at you! Thanks for watching.
