The otsika lathyathyathya theka-ngolo zambiri utenga concave mtengo (kapena bwino mtundu) chimango. Chigawo kutsogolo kwa chimango ndi gooseneck (chikhomo samatha a chigawo kutsogolo kwa gooseneck ndi chikugwirizana ndi samatha chishalo pa thalakitala, kumbuyo mapeto a gooseneck chikugwirizana ndi chimango theka-ngolo), chigawo chapakati ndi katundu nsanja (kunsi kwa chimango), ndipo mapeto kumbuyo ndi gudumu chimango (kuphatikizapo mawilo).

Pamene potsegula zida makina pa otsika lathyathyathya theka-ngolo, izo kawirikawiri imangolongeza zipangizo makina ku mapeto kumbuyo kwa theka-ngolo, mwachitsanzo anasamutsa zida makina kuchokera kumbuyo chimango gudumu kapena kuchotsa mawilo, kenako kukonza zida mawotchi pa theka-trailer.The lathyathyathya theka-ngolo ndi abwino kwa mayendedwe a mitundu yosiyanasiyana ya zida makina, chinthu chachikulu, khwalala zida zomangamanga lalikulu matupi thanki, zida siteshoni mphamvu ndi mankhwala osiyanasiyana zitsulo. "Popita" Dalaivala ananena kuti otsika lathyathyathya theka-ngolo ali lathyathyathya mtundu, mtundu concave mtengo ndi tayala poyera mtundu dongosolo, ndi mtengo kotenga utenga lathyathyathya mtundu kapena mtundu gooseneck.

Ntchito ya nyumba otsika lathyathyathya theka:

Nthawi zambiri ntchito magalimoto zoyendera lolemera (monga mathirakitala, mabasi, magalimoto yapadera, etc.), magalimoto njanji, makina migodi, nkhalango makina, makina zomangamanga (monga anakumba zinthu zakale, magalimoto okonzera, loaders, pavers, cranes, etc.) ndi lolemera zinthu zina. M'munsi pakati yokoka bwino mtendere ndi chitetezo, ndi mphamvu luso zoyendera wapamwamba katundu mkulu ndi kudali mavuto pamwamba.

The mitundu ikuluikulu ya otsika lathyathyathya theka-ngolo ndi: awiri chitsulo chogwira matayala mkulu ndi otsika, awiri mzere anayi chitsulo chogwira matayala mkulu ndi otsika, atatu chitsulo chogwira matayala mkulu ndi otsika, atatu mzere asanu chitsulo chogwira matayala mkulu ndi low.Low lathyathyathya theka-ngolo zimagwiritsa ntchito yonyamula lalikulu zovuta unagawanika katundu zikuluzikulu monga anakumba zinthu zakale, etc., mpanda mtundu ndi abwino kwambiri chifukwa kukoka katundu watsopano, monga masamba, zipatso, etc. galimoto mtundu ndi abwino kwambiri chifukwa kukoka katundu chochuluka ndi katundu wofunika kwambiri ndi chinyezi
