EX30/55/100/200/400 Excavator Track Top Carrier Roller Undercarriage Parts
for Construction Machinery
1. What Is top/carrier track ?
The track, which is situated on the uppermost or carrier area of heavy equipment, fulfills vital functions: it bears weight, provides necessary traction, and serves as a shock absorber. Routine maintenance of this track is crucial in ensuring its seamless operation and extending its operational life.

2. Advantages / Features
(1) An internal circulation system of high efficiency has been implemented.
(2) The shaft is made from top-quality round steel or forged steel.
