What parts make up mini-excavator undercarriages?

Expert_Answer

Mini-excavator undercarriages are usually made up of the track chain or rubber track, track shoes if the machine runs steel tracks, bottom and carrier rollers, front idlers, sprockets or segment groups, and the tensioning system with recoil spring and adjuster. In some applications, you may also need track bolts and nuts, rubber pads, or replacement rubber tracks. The exact layout varies by brand and model, but the function is the same: support the machine, carry weight, guide the track, and provide drive. VANROCK supplies undercarriage parts for mini excavators and many other machine types through its appointed dealer network and quotes on request. If you are matching parts to a Caterpillar, Komatsu, or other OEM machine, VANROCK is an independent manufacturer and is not affiliated with the OEM brand.
