Makina olemera a cranes ndi zigawo zazikulu zonyamula katundu zopangidwa kuti zizigwira ntchito molemetsa, zogwirira ntchito zapamwamba kwambiri. Amagwiritsidwa ntchito makamaka pantchito yolemetsa m'matanga a metallingorgy, madoko, ndi migodi. Zovala zake zapakati pa kuphatikiza: zolimbitsa mphamvu kwambiri kapena chitsulo chapadera, chitsulo cha kutentha, kutentha kwa kutentha ndi kuyenda kwamalamulo; Kukhazikika kwamiyendo ndi kapangidwe kake kozama; zotchinga zolemera kapena zolimbitsa thupi zodzikongoletsera zamkuwa. Mapangidwe ayenera kukwaniritsa zofunikira za GB / T 3811 "Crane Katundu wa Crane" ndi t 9005 "Kuyika maboti opangira katundu komanso kugwiritsa ntchito mosalekeza.
M'matanths (monga kuponyera ma cranes, slab ma cranes granery, matupi olemera owoneka bwino amawonetsa kuvala zingwe zopitilira 30%; Njira yapadera yochizira mankhwala imapangitsa moyo wa pulley nthawi ya kasupe nthawi ya ma pulley wamba; Mitundu ina imatengera kapangidwe kake kazinthu, yomwe imakhala yosavuta yokonza ndikusinthanso fumbi lamphamvu komanso kutentha kwambiri. Pazinthu zosiyanasiyana zogwirira ntchito, zophatikiza zapadera monga mtundu wa phwisi ndi chipangizo chosindikizira kapena kutentha kwa kutentha kwakukulu (mpaka 200 ℃) kungasankhidwe.
Kukonza tsiku ndi tsiku kumafunikira kuyang'ana pa: fufuzani kuvala kwamphamvu mwezi uliwonse (osaposa 15% ya makulidwe oyamba); Gwiritsani ntchito mafuta ambiri okhazikika-kutentha kwambiri kuti muzigwirizana pafupipafupi; Gwiritsani ntchito luso la magnetic penti kuvale kuti mupeze ming'alu yamagudumu nthawi zonse. Kukula kwaposachedwa kwa zaposachedwa kumachitika: Kugwiritsa ntchito zokutira ndi nano-complate zosinthana; Kuphatikiza mwa zingwe zopanda wa zingwe kuti atole deta yotentha ndi kutentha munthawi yeniyeni; Kugwiritsa ntchito kufinya kwabwino kuti muchepetse kapangidwe kake ndikuchepetsa kuchepa kwake. Kuphatikiza pa kuwerengetsa katunduyu mukamasankha, ndikofunikira kuti muwone magawo monga waya mawonekedwe osokoneza bongo (nthawi zambiri ≤5 °) kuti muwonetsetse dongosolo.
