Zovala za nayilonindizopepuka komanso zosavuta kuziyika pamalo okwera.Monga chowonjezera cha tower crane, chimagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zonyamulira.Ndi mawonekedwe ake apadera, pang'onopang'ono adalowa m'malo mwazitsulo zakale zachitsulo.Ichi ndi chida chomwe chingalowe m'malo mwachitsulo ndi pulasitiki.

Lili ndi izi:

1. Kudzipaka mafuta, moyo wautali wautumiki pa kutentha kochepa.

2. Kulemera kopepuka, koyenera kuyika pamalo okwera, kukana kuvala bwino komanso moyo wautali wautumiki.

3. Palibe kukangana kwamoto, chitetezo cholimba chachitetezo, chomwe chingakwaniritse zofunikira za ntchito yakunja kwa nthawi yayitali.

4. Tetezani chingwe cha waya ndikutalikitsa moyo wautumiki wa chingwe cha waya.Chiyerekezo cha moyo wautumiki wa chingwe cha waya ku moyo wautumiki wa pulley yachitsulo imatha kukulitsa moyo wautumiki wa chingwe cha waya ndi nthawi 8.

Pali mitundu iwiri ikuluikulu ya nayiloni pulleymankhwala.Chimodzi mwa izo ndi gudumu la lamination, lomwe limapangidwa kuchokera ku nsalu zoyera za mafakitale ndi zokutira zogudubuza.Zovalazo zimayikidwa motsatizana ndikukanikizidwa, kenako zimaphikidwa ndi kuchiritsidwa mu uvuni, kenako kufa-kudulidwa.Limodzi ndi gudumu lopindika, lomwenso limakutidwa mofananamo, kukulunga ndi ndodo pamtengo wapadera, ndiyeno amawotcha kuti achire.

Mtundu wathumba la nayiloniZogulitsa nthawi zambiri zimakhala zoyera zachikasu kapena zoyera zamkaka.Chifukwa nayiloni ndi zinthu za polima, zimakhala ndi mphamvu zamakina apamwamba, zomwe zimatha kufika ku mphamvu yazitsulo.Njira yosavuta yowunika ndikuyimenya ndi nyundo ndikuwona momwe ikuvutira.Mapuleti a nayiloni ngati gudumu ndi lolimba mokwanira, ma pulleys apulasitiki mwanjira ina.
