Ngingazi kanjani izincazelo zeketanga kanye nemodeli?

1. Kala iphimbo leketanga kanye nebanga eliphakathi kwamaphini amabili;

2. Ububanzi besigaba sangaphakathi, le ngxenye ihlobene nobukhulu be-sprocket;

3. Ubukhulu bepuleti leketanga ukuze wazi ukuthi liluhlobo oluqinisiwe yini;

4. Ububanzi bangaphandle be-roller, amanye amaketanga okuhambisa asebenzisa ama-roller amakhulu.

Ngokuvamile, imodeli yeketanga ingahlaziywa ngokusekelwe kudatha emine engenhla. Kunezinhlobo ezimbili zamaketanga: uchungechunge lwe-A kanye nochungechunge lwe-B, olune-pitch efanayo kanye nobubanzi obuhlukile bangaphandle bama-rollers.

Amaketanga ngokuvamile ayizixhumanisi noma izindandatho zensimbi, ezisetshenziswa kakhulu ekudluliseni nasekubambeni ngomshini. Amaketanga asetshenziselwa ukuvimba izindlela zokuhamba (njengasemigwaqweni, ekungeneni kwemifula noma emachwebeni), kanye namaketanga asetshenziselwa ukudlulisa ngomshini.

1. Uchungechunge luhlanganisa uchungechunge olune:

uchungechunge lokudlulisa, uchungechunge lokuhambisa, uchungechunge lokuhudula, uchungechunge olukhethekile lochwepheshe

2. Uchungechunge lwezixhumanisi noma amasongo, ngokuvamile ensimbi

Amaketanga asetshenziselwa ukuvimba izindlela zokuhamba (isib. emigwaqweni, ekungeneni kwemifula noma emachwebeni);

Amaketanga okudlulisela ngomshini;

Amaketanga angahlukaniswa ngamaketanga ama-roller aqondile ane-pitch emfushane, amaketanga ama-roller aqondile ane-pitch emfushane, amaketanga ama-roller epuleti eligobile okudlulisela umthwalo osindayo, amaketanga emishini yesamente, kanye namaketanga amapuleti;

Uchungechunge lwezintambo zokubopha uchungechunge olunamandla aphezulu, olusetshenziswa ngobungcweti ekusekeleni ubunjiniyela, ekusekeleni ukukhiqiza, ekusekeleni umugqa wokukhiqiza kanye nasekusekeleni imvelo ekhethekile.
