Makhalidwe ogwirira ntchito a crane ndikuyenda kwapakatikati, ndiko kuti, njira zofananira zobweza, kunyamula ndi kutsitsa mumayendedwe ogwirira ntchito mosinthana.Lililonse limagwirira nthawi zambiri limagwira ntchito poyambira, mabuleki ndikuthamanga mbali zabwino ndi zoyipa.
(1) Gulu la makina okweza
1. Malingana ndi chikhalidwe chokweza, chikhoza kugawidwa kukhala: makina onyamula osavuta ndi zida: monga Jack (rack, screw, hydraulic), pulley block, hoist (manual, magetsi), winch (manual, magetsi, hydraulic), kupachika monorail, etc;Cranes: ma cranes oyenda, ma cranes a tower ndi ma mast cranes amagwiritsidwa ntchito kwambiri muukadaulo wamakina amagetsi.
2.Malinga ndi mawonekedwe apangidwe, akhoza kugawidwa kukhala: mtundu wa mlatho (crane ya mlatho, gantry crane);Mtundu wa chingwe;Mtundu wa Boom (yodziyendetsa yokha, nsanja, portal, njanji, sitima yoyandama, crane ya mast).
(2) Kuchuluka kwa kugwiritsa ntchito makina okweza
1. Crane yam'manja: imagwira ntchito pakukweza zida zazikulu ndi zapakatikati ndi zida zokhala ndi zolemetsa imodzi, zokhala ndi nthawi yayitali.
2. Tower crane;Imagwiritsidwa ntchito pakukweza zida, zida (zida) zokhala ndi kuchuluka kwakukulu mkati mwa kukula ndi kulemera kochepa kwa chidutswa chilichonse, ndikuzungulira kwanthawi yayitali.
3. Crane ya mast: imagwira ntchito makamaka pakukweza zinthu zina zolemetsa, zapamwamba kwambiri komanso malo okhala ndi zoletsa zapadera.
(3) magawo oyambira pakusankhidwa kwa crane
Iwo makamaka zikuphatikizapo katundu, oveteredwa kukweza mphamvu, pazipita matalikidwe, pazipita kukweza kutalika, etc. magawowa ndi maziko ofunika kupanga hoisting luso chiwembu.
1. Katundu
(1) Katundu wamphamvu.Ponyamula zinthu zolemera, crane imatulutsa inertia.Mwachizoloŵezi, kulemedwa kwa inertial kumeneku kumatchedwa dynamic load.
(2) Katundu wosakwanira.Pamene nthambi zingapo (ma cranes angapo, seti angapo a pulley midadada, angapo slings, etc.) kukweza chinthu cholemera pamodzi, chifukwa cha zinthu asynchronous ntchito, nthambi iliyonse nthawi zambiri sangathe kunyamula katundu molingana ndi gawo lokhazikitsidwa.Pakukweza uinjiniya, chikokacho chimaphatikizidwa mu coefficient yolemetsa yosakwanira.
(3) Werengetsani katundu.Mu mapangidwe a hoisting engineering, pofuna kuganizira mphamvu ya katundu wamphamvu ndi katundu wosayenerera, katundu wowerengeka nthawi zambiri amagwiritsidwa ntchito ngati maziko owerengera kukweza ndi chingwe ndi kufalitsa.
2. Chovoteledwa kukweza mphamvu
Pambuyo pozindikira utali wozungulira komanso kutalika kokweza, crane imatha kukweza kulemera kwake.Mphamvu yokwezedwa yovotera ikhala yayikulu kuposa katundu wowerengeredwa.
3. Kukula kwakukulu
Kutalikirana kokwererako kozungulira kozungulira kwa crane, mwachitsanzo, makwerero okwera pansi pa mphamvu yokwezera.
