A kusokoneza katundu binder, yomwe imatchedwanso ratchet binder kapena lever binder, ndi chida chomwe chimagwiritsidwa ntchito poteteza ndi kukanikiza katundu wolemetsa panthawi yoyendetsa kapena kusunga. Amagwiritsidwa ntchito kwambiri m'mafakitale oyendetsa magalimoto, zomangamanga, zaulimi, ndi zotumiza.
Chomangira cholumikizira chimakhala ndi chogwirira, cholumikizira, ndi zokowera ziwiri kapena zolumikizira kumapeto. The tensioning limagwirira ntchito ndi ratcheting gear system, amene amalola wosuta kumangitsa binder pang'onopang'ono kukwaniritsa kukangana amafuna.
Chomangiracho chimamangiriridwa ku mbali ziwiri za unyolo, chingwe chawaya, kapena lamba lomwe limagwiritsidwa ntchito kuteteza katunduyo. Mbali imodzi ya chomangira imalumikizidwa ndi nangula pagalimoto, ngolo, kapena bedi lonyamula katundu, pomwe mbali inayo imalumikizidwa ndi katundu wokha.
Pofuna kukanikiza chomangira, wogwiritsa ntchito amagwiritsa ntchito njira yolumikizira pokokera chogwiriracho mmbuyo ndi mtsogolo. Ndi kukoka kulikonse kwa chogwirira, chomangiracho chimalimba mochulukira, kuyika kukakamiza pa katundu wotetezedwa ndikuchepetsa kufooka kulikonse mu dongosolo lomangira.
Kukakamira komwe kumafunidwa kukwaniritsidwa, makina a ratchet amatseka m'malo mwake, kuletsa chomangiracho kuti chisamasuke ndikusunga kupsinjika pa katunduyo. Zomangira zina zomangira zimatha kukhala ndi makina otsekera kapena pini yachitetezo kuti muteteze chogwiriracho pamalo otsekedwa.
Kuti mutulutse zovutazo ndikuchotsa chomangira, wogwiritsa ntchito nthawi zambiri amachotsa cholumikiziracho pokoka levu kapena batani lotulutsa, kulola chogwiriracho kuti chitseguke mokwanira komanso kutulutsako pang'onopang'ono.
Zomangamanga zonyamula katunduperekani maubwino angapo pa zomangira zachikhalidwe za lever, kuphatikiza kukanikizana kosavuta komanso kolamulirika, chitetezo chowonjezereka, komanso kuthekera kosintha bwino kupsinjika. Komabe, amafunikira kuphunzitsidwa koyenera komanso kusamala kuti agwiritse ntchito mosamala, chifukwa kumangirira mopitilira muyeso kumatha kuwononga katundu kapena dongosolo lomangirira. Ndikofunika kutsatira malangizo a wopanga ndi malamulo okhudzana ndi chitetezo mukamagwiritsa ntchitozomangira katundu.
