Mu zochitika zogwirira ntchito m'madzi, ma crane a m'madzi amagwira ntchito ngati zida zoyambira zonyamulira/kutsitsa katundu. Kugwira ntchito kwawo motetezeka komanso moyenera kumadalira kusintha kolondola kwa kayendedwe ka zombo —chidendene ndi kudulaNdi magawo ofunikira kwambiri a kapangidwe kake omwe amatsimikiza mwachindunji mphamvu ya kapangidwe kake, mphamvu yonyamula katundu, ndi kukhazikika kwa magwiridwe antchito a ma cranes.MAXTECHKampani yodziwika bwino padziko lonse lapansi yopanga ma crane am'madzi, mwachitsanzo, imaphatikiza zofunikira pakupanga chidendene ndi zokongoletsa mu miyezo yayikulu ya kapangidwe kake kazinthu zonse. Kudzera mu kuwongolera kawiri kotsatira malamulo ndi magwiridwe antchito, MAXTECH imawonetsetsa kuti magwiridwe antchito ndi otetezeka pansi pa mikhalidwe yosiyanasiyana ya panyanja.
1. Tanthauzo Lalikulu la Chidendene ndi Kudula
1.1 Chidendene
Chidendene chimatanthauza kupendekera kopingasa kwa chombo chozungulira mzere wake wakutsogolo ndi kumbuyo, mwachitsanzo, kusiyana kwa kutalika pakati pa mbali za doko ndi bolodi la nyenyezi, komwe kumayesedwa mu madigiri (°). Chifukwa cha mphepo, mafunde, kapena kunyamula/kutsitsa katundu kosagwirizana, chidendene chimakhudza mwachindunji kulimba kwa ma crane booms ndi kutsika kwa malo osungira katundu a mphamvu yokoka, zomwe zimagwira ntchito ngati chizindikiro chachikulu cha kukhazikika kwa crane mbali.
1.2 Kudula
Kudula kumatanthauza kupendekera kwa chombo chozungulira mzere wake wopingasa, mwachitsanzo, kusiyana kwa kutalika pakati pa uta ndi kumbuyo, komwe kumayesedwa mu madigiri (°). Chifukwa cha kusintha kwa kulemera kwa chombo, kuponya kwa mafunde, kapena kusintha kwa malo onyamula katundu, kudula kumasintha ngodya ya ma crane booms ndi kugawa kwa katundu wonyamula katundu, zomwe zimakhudza mphamvu ya ma booms ndi maziko.
Zombo zimagwira ntchito mosalekeza pansi pa zidendene ndi zokongoletsa panyanja. Pophatikizidwa ndi katundu wosinthika wochokera ku ntchito zonyamula, izi zimapangitsa kuti zigawo zofunika kwambiri za crane (monga maziko, ma boom, ndi ma bearing odulidwa) zikhale zolimba pamodzi. Popanda kapangidwe kake ka ma ngodya opendekera, zomangamanga zimatha kusokoneza, kusweka, kapena kutaya kukhazikika. Popanga ma knuckle boom ake ndi ma telescopic boom marine cranes, MAXTECH imachita kusanthula kwa zinthu zocheperako kutengera ma ngodya opendekera wamba kuti iwonetsetse kuti ma boom, ma pini, mapaipi a hydraulic, ndi zigawo zina zikukwaniritsa zofunikira zamphamvu pansi pa zovuta zophatikizana.
2.2 Kukwaniritsa Zofunikira pa Malamulo kuti Zitsimikizire Kutsatira Malamulo
Ma cranes a m'madzi ayenera kupeza ziphaso kuchokera ku mabungwe otsogola monga CCS, BV, ndi ABS.chidendene cha ≤5° ndi chokongoletsa cha ≤2°ndiye muyezo wogwirizana padziko lonse lapansi wogwirira ntchito. Mwachitsanzo, IMO MSC.1/Circ.1477 imati ma cranes ayenera kugwira ntchito mosamala ali ndi katundu wathunthu pansi pa chidendene cha 5° nthawi imodzi ndi trim ya 2° pa ntchito za doko. The China Classification Society (CCS)Malamulo a Zipangizo Zonyamulira M'zombo ndi Kukhazikitsa M'nyanjaimagwiritsanso ntchito ma angles awa ngati muyezo wowerengera katundu wotetezeka wogwirira ntchito (SWL). Zogulitsa za MAXTECH zimatsatira malamulowa kuti zipeze mwayi wopeza misika yapadziko lonse lapansi yapamadzi.
2.3 Kusinthana ndi Mavuto a Nyanja Kuti Muwonjezere Ntchito
Kawirikawiri, zombo zimatha kupitirira mikhalidwe yokhazikika yogwirira ntchito chifukwa cha momwe nyanja ilili, zomwe zimapangitsa kuti chidendene cha 5°–7° ndi kudulidwa kwa 2°–3°. Zikatero,kapangidwe kochepetsera kutengeka ndi katundundikofunikira kuti ntchito ziyende bwino. Ngati chidendene chapitirira 7° kapena chokongoletsera chapitirira 3°, kukweza kuyenera kuyimitsidwa ndipo chowongolera chombocho chisinthidwe. Makina a crane a MAXTECH a AHC (Active Heave Compensation) amagwiritsa ntchito ukadaulo wowongolera mayendedwe kuti agwirizane ndi nyengo yovuta ya nyanja, zomwe zimapangitsa kuti ntchito ziwonjezeke.
3. Miyezo Yopangira Kapangidwe ndi Malangizo Othandiza pa Chidendene ndi Kudula
3.1 Miyezo Yopangira Mapangidwe Aakulu
| Mkhalidwe Wogwirira Ntchito | Kufunika kwa Chidendene | Kufunika Kochepetsa | Chitsanzo Choyenera |
| Mkhalidwe Woyenera Wogwirira Ntchito | ≤5° | ≤2° | Ntchito zachizolowezi m'madoko ndi m'madzi otetezedwa |
| Mkhalidwe Wogwira Ntchito Wochepetsedwa ndi Katundu | 5°–7° | 2°–3° | Nyanja yofewa; ntchito yochepetsa katundu pa tchati chilichonse cha katundu |
| Mkhalidwe Woletsedwa Wogwirira Ntchito | ＞7° | ＞3° | Mavuto a panyanja oopsa; kusintha momwe sitimayo imaonera kumafunika |
| Mkhalidwe Wosungira Zinthu Zosagwira Ntchito | ≤30° | ≤10°–15° | Kuyenda kwa sitima; ma bearing a kapangidwe kokha |
3.2 Machitidwe a Kapangidwe ka MAXTECH
- Kapangidwe Kotsatira Malamulo: Mitundu yonse imakwaniritsa malamulo a BV ndi CCS, popanda kuchepetsa katundu wovomerezeka pansi pa mikhalidwe yokhazikika. Kudalirika kwa kapangidwe kumatsimikiziridwa kudzera mu mayeso angapo a mphamvu.
- Kusintha Koyenera: Kwa madera apadera omwe ali ndi kutentha kwambiri komanso nyengo yovuta ya panyanja (monga Middle East), machitidwe a hydraulic ndi mphamvu ya kapangidwe kake zimakonzedwa bwino kuti zitheke kugwira ntchito bwino pansi pa mikhalidwe yochepetsedwa (chidendene ≤7°, chodulira ≤3°), choyenera zombo zotumikira papulatifomu.
- Chitetezo cha Chitetezo: Yokhala ndi makina owongolera opanda zingwe komanso chitetezo chowonjezera mphamvu zomwe zimadziwitsa zokha pamene chombo chikuyandikira malire a chitetezo. Mapangidwe a mapaipi a hydraulic amakonzedwa bwino kuti apewe kutayikira kwa mafuta komwe kumachitika chifukwa cha kupendekera.
4. Mapeto
Chidendene ndi chokongoletsera ndi zinthu zofunika kwambiri pakupanga makina a crane, zomwe zimagwirizana mwachindunji ndi chitetezo cha zida, kutsatira malamulo, komanso kugwira ntchito bwino. Kuyambira pakupanga kogwirizana ndi zinthu zomwe zili munthawi yoyenera mpaka kusintha kwa kuchepetsa katundu pazochitika zovuta kwambiri, komanso kukonza bwino zinthu zinazake, sitepe iliyonse iyenera kutsatira malamulo ndi zosowa zenizeni. Ndi chidendene ndi chokongoletsa ngati zinthu zofunika kwambiri pakupanga, MAXTECH imayang'anira unyolo wonse waukadaulo kuti ipatse makasitomala apadziko lonse lapansi njira zodalirika zonyamulira zomwe zingagwirizane ndi zochitika zosiyanasiyana zapamadzi, kutsimikizira udindo waukulu wa magawo awiriwa pakupanga makina a crane.
