Mga tampok at kinakailangan
Ang function ng track roller ay upang ipadala ang bigat ng locomotive unit sa lupa at gumulong sa track.Upang maiwasan ang pagkadiskaril, dapat ding pigilan ng track roller ang crawler na magdulot ng lateral relative movement dito.
ang track roller ay madalas na gumagana sa putik, tubig, abo at buhangin, at may malakas na epekto.Ang mga kondisyon sa pagtatrabaho ay lubhang masama at ang mga rim ay madaling isuot.
Ang mga kinakailangan para sa mga track roller ay: wear-resistant rims, maaasahang bearing seal, at mababang rolling resistance.
