Kufotokozera
Kuphatikiza apo, zinthu za PVC zimalimbana kwambiri ndi kutentha kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito chaka chonse. Kaya kuli kotentha kapena nyengo yozizira, zingwezi sizikhudzidwa, zimasunga mphamvu ndikugwira ntchito pakapita nthawi. Kukhazikika kumeneku ndikofunikira kwambiri chifukwa kumatsimikizira kuti chingwecho chimagwira ntchito yake modalirika mosasamala kanthu za momwe chilengedwe chimakhalira. Kugwiritsiridwa ntchito kwa mapangidwe a buckle kumawonjezeranso magwiridwe antchito ndi magwiridwe antchito a zingwe izi. Zomangamanga zimapangidwira kuti azigwira lamba motetezedwa ku corbel kuonetsetsa kuti lambalo likhalabe pamalo ake ngakhale nyama zikuyenda. Izi zimachepetsa chiopsezo cha lamba kuterereka kapena kugwa, kuteteza ngozi zomwe zingachitike kapena kusokoneza nyama ndi alimi.
Chinthu chinanso chodziwika bwino cha zingwe za phazi zolembera izi ndikugwiritsanso ntchito. Zingwezo zimatha kuchotsedwa mosavuta ng'ombe zikakula kapena sizikufunikanso, ndipo mapangidwe ake amathandizira izi. Kuonjezera apo, zingwezo zimatha kusinthidwa ndikumasula kapena kulimbitsa chingwe, kulola kusintha kukula kwa ng'ombe ndi chitonthozo. Zomangira zomangira phazi zopangidwa ndi zinthu za PVC zimapereka chokhazikika, chosagwira kutentha komanso njira yabwino yogwiritsira ntchito posamalira ng'ombe. Kufewa kwawo komanso kukana kusweka kumatsimikizira moyo wawo wautali, kuonetsetsa kuti atha kupirira zofuna za ng'ombe. Mapangidwe a buckle amatsimikizira kukwanira kotetezeka pomwe kumakhala kosavuta kugwiritsa ntchito ndikusintha. Ndi zabwino izi, alimi amatha kugwiritsa ntchito bwino zingwezi kuti apititse patsogolo kasamalidwe ka ng'ombe zawo komanso kugwira ntchito moyenera.
