Premature wear in sand applications

[dragonlady]

case tr270 is used in sand and sprockets,sometimes rubber tracks, have to be replaced every 6 months. other then how it is being driven, are there any heavier duty options for sprockets to longer use?

Sand is the worst thing on sprockets, especially a CTL that can move so quickly. Maybe worn sprockets could be build up with hardfacing before they're totally shot.

How many hours of use during the 6 months?

 

[dragonlady]

1ST TIME WE REPLACED BOTH SPROCKETS AND TRACKS AT 430HRS, 2ND TIME WE REPLACED SPROCKETS AT 613, NOW WE ARE LOOKING AT TRACKS AND SPROCKETS AT PROBABLY NO MORE THEN 200HRS.

What brand of tracks and sprockets are you buying?

Some of the Chinese/Asian tracks are crap. I've burned through the cheap ones $1200 or so a piece in 200-300 hours. The Bridgestone's that came on my 279D new two years ago are at 60% at 600 hrs.

I'll spend double the money and buy Bridgestone or a well know manufacturer from now on.

Wet sand is the worst. Top quality parts will help lower the per hour cost. Service in the coal pile is the best in terms of wear. Almost unbelievable undercarriage life
