CAT Track Wear Simulator

Demonstration of CAT Works and Wears simulator showing what causes track wear and why it occurs faster during reverse operation than forward operation.

Thanks for the professional presentation. No rhetoric, just factual, great job.

[@nickemrick7466]

Where I work at currently, some of the parts we make are for cat. And some include different size links, like seen in the beginning assembly animation. And also, toothed segments that would be assembled together to form one big toothed circle, looking like the sprocket

Traction: my favourite pet subject - tyres or / and tracks - place for all. Now this is at another level. Was always dubious about your Hi-level tracks - nobody could teach me / point me inthe right direction. TOnight I fell down the youtube rabbithole. Fascinating: The grief I get from folk who have NO or Less idea than I have ( and from an engineering perspective and user, too ). Not just the Pin / Sprkt wear, but also the loading on the Pads. TOrq reaction from pulling .... not what we've been taught about crawlers v Tires. THink I was right all along. Thanks you for posting and hope it generates more educated debate. Slàinte Mhath

What’s really crazy is that coal dust has graphite which lubricates, and there are dozers with tens of thousands of hours with brand new looking original tracks/rollers/sprockets in coal mines

[@JimMackHeavyEquipment]

Thanks for sharing that Cody G; that is crazy situation where undercarriage life is extended greatly by the operating conditions!

[@jimmycricket5366]

It very much depends on the type of coal. There are coal mines where the exact opposite is true, whereby the coal has a high silica content, so the coal is blended with sand/grit.

For first-timer this is god. Very! Thank you.

[@victor-emmanuel7485]

Very interesting, thanks for sharing 👍

This content needs to be sent to the operators apprenticeship for learning the students on how the wear occurs.

[@adamdodds869]

Also I used to work for a company that would refuse to change out the worn sprockets and also allow the chain pitch to get really long. The result was the sprocket tip to come into contact with the bushing at an approach angle where the tooth tip would try to climb over to the next bushing or "jump" a tooth. It sounds horrible and is also horrible for the machine. Proper maintenance for tracks is key to any tracked machine.

[@ricknone4686]

I've ran D10N thru D11T and the wear ripping on the tracks was mostly seen on rail between pins ,I've seen them so bad that operator couldn't stand it in the seat on any kind of hard surface and was actually shaking and vibrating machine apart! Had several track techs come out and say because sprocket and pins didn't show wear that they where still 75% good? I would say measure rail height at pins and then in middle between pins! I've seen anywhere between 1" to 11/2" or more difference! It kills operator eats horsepower and vibrates shaking machine! Also seen rails wear flats on Idlers from hitting same spot continuously! Flat tracks on D9H would usually wear out pins and bushings!

Thanku for educating video I want to know how designing of mini excavator track roller is done particularly inside can you help me out if you have any information

[@michaelmccaffrey2731]

This is why many companies are going back to flat tracks. They sell more tracks. High tracks have less wear while backing up apposed to flat tracks

[@VinothKumar-rf5od]

Great explanation sir.. Can u pls elaborate about seals used in track seals?

[@daleolson3506]

Do they take in to account if they source the parts from China?

[@JimMackHeavyEquipment]

Actually tracks were invented far before WWII, being used commercially in 1901 and by the Holt manufacturing company in 1904.

tienen este simulador en español???

[@JimMackHeavyEquipment]

Hello Manuel, thanks for the suggestion. I do not currently have the audio available in Spanish but I added some subtitles in Spanish so hopefully that helps.

[@Wolfdog370]

Ummm .. you forgot dirt .. dirt is a major contributor to the wear on a sprocket and chain

[@JimMackHeavyEquipment]

Fair point. Sand will wear tracks much faster than other soils like clay. Soil conditions will always affect track wear.

[@dieselengines2619]

Can anyone tell me if the cat drive chain wears out more quickly because of the elevated sprocket?

[@JimMackHeavyEquipment]

Yes, internally it wears out faster because it flexes 3 times per revolution instead of two. However, as long as you use SALT tracks it should prevent this internal wear and not be an issue.

[@dieselengines2619]

@@JimMackHeavyEquipment in my understanding it doesnt just flex and extra time, it has to carry the full load meanwhile it flexes like 110 degrees

[@vince6056]

So pretty much the more you move the machine the more wear🤯

[@JimMackHeavyEquipment]

Of course that is true, but notice that it wears the more you move in reverse compared to moving in forward.

[@ccclc6159]

if cats design is better why does their high drive track wear faster than the oval design?

[@JimMackHeavyEquipment]

I am not sure I would say it is "better". It definitely has some advantages but it also has the disadvantage of having 3 pivot points per revolution, instead of 2 on conventional track. This will cause more internal wear and wear faster unless they used Sealed and Lubricated Track (SALT) which nearly eliminates all internal wear. I do know that on elevated sprocket equipment you need to run SALT tracks because regular sealed track will wear out too quickly.

Where can I download this simulator?

[@JimMackHeavyEquipment]

I don't think you can download it any more, it only worked on flash player.
