Zofalitsa zomwe zimagwiritsidwa ntchito kwambiri ndi mbedza, ndipo zina zimaphatikizapo mphete, makapu onyamulira, zingwe ndi matabwa olendewera.Kukweza makapu oyamwa, zingwe ndi matabwa olendewera atha kugwiritsidwa ntchito ngati zofalitsa zapadera pa crane kwa nthawi yayitali, komanso zitha kugwiritsidwa ntchito ngati zofalitsa zowonjezera zosinthika pazingwe kuti zigwiritsidwe ntchito kwakanthawi.Nthawi zambiri amagwiritsidwa ntchito m'malo osungiramo zinthu komanso mayadi amitundu yambiri yazinthu kuti apititse patsogolo magwiridwe antchito.
Mitundu ikuluikulu ya zingwe zamawaya achitsulo imaphatikizapo chingwe chachitsulo chophimbidwa ndi phosphating, chingwe chachitsulo cha galvanized ndi chingwe chosalala chachitsulo.Deta yofananira ikuwonetsa kuti kudzoza kwa chingwe chachitsulo chachitsulo kumakhudza kwambiri moyo wautumiki wa chingwe chachitsulo chachitsulo kuchokera kusanthula pamwambapa.Kudzoza mwadongosolo kwa chingwe cha waya kumatha kukulitsa moyo wa chingwe cha waya ndi nthawi 23
Ngati kuzungulira kwa loko yokhotakhota sikusinthika kapena kulibe, yang'anani kusinthako,
Mukamagwiritsa ntchito, pewani utoto wa chizindikiro pagawo lowonetsa la chowulutsa chokweza kuti lisagwe.Akapezeka, m'pofunika kusintha utoto ndi chizindikiro choyambirira mu nthawi
Kukweza kuyenera kuchitika pang'onopang'ono panthawi yokwezera kuti zisawonongeke chifukwa cha kugundana pakati pa chonyamulira chonyamulira ndi crane kapena zida zina.
Muyezo wamakampani aku China ndi JB T8521, wokhala ndi chitetezo cha 6: 1, zomwe zikutanthauza kuti katundu wonyamula lamba wonyamulira ndi 1T, koma sudzasweka mpaka atakokedwa kupitilira 6T.
Pali maunyolo 4 a matani 55, ndipo chilichonse chachitetezo ndi nthawi zinayi za nambala yowerengera.Imatengera kukweza mfundo za 4 ndipo chitetezo ndi nthawi 1.3, zomwe zimakwaniritsa zofunikira za malamulo okweza dziko.
Mukakweza, gwiritsani ntchito njira yolumikizira gulaye moyenera.Choponyeracho chiyenera kuikidwa ndi kulumikizidwa ndi katunduyo motetezeka.Choponyeracho chiyenera kuikidwa pa katundu kuti katunduyo akhale wolinganizika.M'lifupi mwa gulaye;musapange mfundo kapena kupindika legeni.Gawolo silingayikidwe pa mbedza kapena zida zonyamulira, ndipo nthawi zonse zimayikidwa kumbali yowongoka ya gulaye, kuteteza chizindikirocho kuti chisawonongeke pokhala kutali ndi katundu, mbedza ndi ngodya yotseka.
