Ibikoresho biremereye bikurikiranwa munsi ya gari ya moshi bitanga inyungu zinyuranye zituma baba indashyikirwa mubikorwa bitandukanye. Dore zimwe mu nyungu zingenzi:
1. Umuvuduko wo hasi: Igishushanyo cya chassis ikurikiranwa ituma ikwirakwiza uburemere no kugabanya umuvuduko wubutaka. Ibi bibafasha gutembera kubutaka bworoshye, ibyondo cyangwa ahantu hataringaniye hamwe no kwangirika kubutaka.
2. Gukurura cyane: Inzira zitanga ahantu hanini ho guhurira, zongerera imbaraga ibikoresho kubutaka butandukanye. Ibi bituma imashini zikurura zikora neza ahantu hahanamye, ubutaka bwumucanga nibindi bidukikije bigoye.
3. Guhagarara: Chassis ya crawler ifite centre yo hasi yububasha, itanga ituze ryiza, cyane cyane mugihe ikora ubucukuzi, guterura cyangwa ibindi bikorwa biremereye, bigabanya ibyago byo gutembera hejuru.
4. Guhuza n'imihindagurikire y'ikirere: Chassis ikurikiranwa irashobora guhuza nubutaka butandukanye nibidukikije, harimo imisozi ihanamye, ibyondo bitonyanga nubutayu, kandi ifite uburyo bwinshi bwo kubisaba.
5. Kuramba: Chassis ikurikiranwa mubusanzwe ikozwe mubikoresho bikomeye cyane, hamwe no kwihanganira kwambara no kurwanya ingaruka, bikwiriye gukoreshwa igihe kirekire mubidukikije.
Isosiyete Yijiang ishingiye ku musaruro wihariye wa gari ya moshi zikoreshwa, gutwara ubushobozi ni toni 0.5-150, isosiyete yibanda ku gishushanyo cyabigenewe, kugira ngo imashini zawe zo hejuru zitange chassis ikwiye, kugirango uhuze imikorere yawe itandukanye, ibisabwa byubunini butandukanye.
