Coupler (coupler) ndowe kumapeto kwa ngolo kapena njanji, yomwe imagwiritsidwa ntchito kutchingira, kukoka, ndikuwombera. ndi mphamvu yake, ndikupanga galimoto pakati pa galimotoyo kuti izikhala ndi mtunda winawake wamagalimoto.Chikopa chimapangidwa ndi mutu wa ndowe, thupi la ndowe ndi mchira wa mbedza. Gawo lakuda kutsogolo kwa mbedza limatchedwa mutu wachikopa. Mutu wa mbedza, pali lilime lachikopa, pini yolumikizira, chokozera chokweza, lilime lokukankhira chitsulo ndi chitsulo chotsekera. Mbali yakumbuyo ya coupler amatchedwa mchira wolumikiza, ndipo chingwe chotseguka chotseguka chimatsegulidwa pa mchira wa coupler Kuti muzindikire ndowe kapena ndowe, kuti galimoto ilumikizidwe kapena kulekanitsidwa, ndowe yagalimoto ili ndi malo atatu otsatirawa, zigawo zitatu za ndowe yagalimoto: malo otsekera - ndowe Lilime la ndowe lagalimoto limalephereka ndi chitsulo cholumikizira kuti chisawoneke chakunja. Mbedza ili pamalopo pomwe magalimoto awiri alumikizidwa palimodzi. Malo otsegulira loko - ndiye kuti pomwe chitsulo chimakokedwa ndi Lilime la ndowe limatha kutembenukira panja malinga ngati lakokedwa. Malingana ngati ndowe imodzi ili pamalo otsekera, mutha kusiyanitsa magalimoto awiriwo. malo otseguka kwathunthu - malo omwe lilime loyeserera latembenukira kunja. Magalimoto awiri akafunika kulumikiza ndowe, monga malingana ngati ndowe imodzi ili pamalo otseguka kwathunthu, pambuyo poti kugundana ndi ndowe inayo itha kulumikizidwa. Kapangidwe ka cholumikizira cha rotary ndi chosiyana ndi cha coupler wamba. Mapeto a mbedza ndi gawo, lotsekedwa kutsogolo Mutu wa mbedza umakhala ndi makokedwe, thupi la ndowe, limodzi ndi chikhomo cha mchira ndi malaya ozungulira, zimayenda. Mapeto amodzi a galimoto amakhala ndi chosinthira chozungulira ndipo kumapeto ena ndi cholumikizira chokhazikika. Ma coupler awiri amalumikizidwa awiriawiri m'sitimayo. Galimoto yonyamula malasha ikalowa pamalo otayira pamalowo, dumper amayendetsa galimotoyo kutembenuza madigiri a 180 ndikutaya malasha kunja. tsegulani katundu popanda kuchotsa coupler ndikuchepetsa nthawi yotsitsa. Zolumikizira zazing'ono zimagwiritsidwa ntchito pamagalimoto othamanga kwambiri komanso oyenda pansi panthaka. Ndi yaying'ono kukula, kulemera kwake, ndipo mayendedwe olowera mbali iliyonse amakhala ochepa kwambiri pambuyo polumikizira awiriwo. ndi olumikizidwa, omwe amatha kuzindikira "kulumikizana kwapafupi" kwenikweni. Nthawi yomweyo, ndizothandiza kwambiri kuti pakhale doko lokhazikika la payipi yamagetsi ndi cholumikizira magetsi.
