Ezimweni zokusebenza kolwandle, ama-crane olwandle asebenza njengemishini yokulayisha/yokukhulula. Ukusebenza kwawo okuphephile nokuphumelelayo kuncike ekuzivumelaniseni okunembile nezimo eziguquguqukayo zemikhumbi —isithende kanye nokusikayizici ezibalulekile zokuklama ezinquma ngqo amandla esakhiwo, umthamo womthwalo, kanye nokuzinza kokusebenza kwama-crane.I-MAXTECH, umkhiqizi odumile emhlabeni wonke wama-crane olwandle, njengesibonelo, inkampani ifaka izidingo zesithende kanye nokusika ezindinganisweni zokuklama eziyinhloko zomugqa wayo womkhiqizo ogcwele. Ngokulawula okubili kokuhambisana nokusebenza, i-MAXTECH iqinisekisa ukuphepha kokusebenza ngaphansi kwezimo ezahlukahlukene zolwandle.
1. Izincazelo Eziyinhloko Zesithende Nokunquma
1.1 Isithende
Isithende sibhekisela ekuthambekeni okuphambene komkhumbi ozungeze i-axis yawo yangaphambili nangemuva, okungukuthi, umehluko wokuphakama phakathi kwezinhlangothi ze-port ne-starboard, ezilinganiswa ngamadigri (°). Njengoba kubangelwa umoya, amagagasi, noma ukulayisha/ukukhulula imithwalo okungalingani, isithende sithinta ngqo izinga lama-crane booms kanye nokususwa kwezikhungo zomthwalo wamandla adonsela phansi, okusebenza njengesibonakaliso esibalulekile sokuzinza kwe-crane eceleni.
1.2 Ukunquma
Ukunquma kubhekisela ekuthambekeni komkhumbi okude kakhulu mayelana ne-axis yawo ejikelezayo, okungukuthi, umehluko wokuphakama phakathi komnsalo nengemuva, okulinganiswa ngamadigri (°). Uma kubangelwa izinguquko zesisindo somkhumbi, ukuphonsa okubangelwa amagagasi, noma ukushintsha kwesikhundla somthwalo, ukunquma kushintsha i-engeli yokugoba yama-crane booms kanye nokusatshalaliswa komthwalo okude, okuthinta ibhalansi yamandla ama-boom nezisekelo.
Imikhumbi isebenza njalo ngaphansi kwezimo zesithende kanye nokusika olwandle. Uma ihlanganiswe nemithwalo enamandla evela emisebenzini yokuphakamisa, lokhu kubeka izingxenye ezibalulekile ze-crane (isb., izisekelo, ama-boom, kanye nama-slewing bearings) ekucindezelekeni okuhlangene. Ngaphandle komklamo obala ama-angle okuthambekela, izakhiwo zingase ziphazamiseke, ziqhekeke, noma zilahlekelwe ukuzinza. Lapho iklama ama-knuckle boom ayo kanye nama-telescopic boom marine cranes, i-MAXTECH yenza ukuhlaziywa kwezinto ezilinganiselwe ngokusekelwe kuma-angle okuthambekela ajwayelekile ukuqinisekisa ukuthi ama-boom, amaphini, amapayipi e-hydraulic, nezinye izingxenye zihlangabezana nezidingo zamandla ngaphansi kokucindezeleka okuhlangene.
2.2 Ukuhlangabezana Nezidingo Zokulawula Zokuqinisekisa Ukuthobela Imithetho
Ama-crane olwandle kumele athole izitifiketi ezivela ezinhlanganweni ezihamba phambili zokuhlukanisa njenge-CCS, i-BV, kanye ne-ABS.isithende esingu-≤5° kanye nokunqunywa okungu-≤2°yisimo sokusebenza esijwayelekile esihlanganisiwe emhlabeni wonke. Isibonelo, i-IMO MSC.1/Circ.1477 icacisa ukuthi ama-crane kumele asebenze ngokuphepha ngomthwalo ogcwele ngaphansi kwesithende esisodwa esingu-5° kanye nokunqunywa okungu-2° ekusebenzeni kwechweba. I-China Classification Society (CCS)Imithetho Yezinto Zokuphakamisa Emikhumbini Nasezindaweni Ezingaphandle Kwamanziisebenzisa futhi la ma-engeli njengendlela yokubala i-Safe Working Load (SWL). Imikhiqizo ye-MAXTECH ilandela ngokuqinile le mithethonqubo ukuze ifinyelele ezimakethe zomhlaba wonke zasolwandle.
2.3 Ukuzivumelanisa Nezimo Zolwandle Eziyinkimbinkimbi Ukuze Kwandiswe Ububanzi Bokusebenza
Empeleni, imikhumbi ingadlula izimo zokusebenza ezijwayelekile ngenxa yezimo zolwandle, okuholela esithendeni esingu-5°–7° kanye nokunqunywa okungu-2°–3°. Ezimweni ezinjalo,umklamo wokunciphisa umthwalo othambekelekuyadingeka ukuze kugcinwe ukusebenza ngokuphephile. Uma isithende sidlula u-7° noma ukusika kudlula u-3°, ukuphakamisa kumele kumiswe futhi kulungiswe i-ballast yesikebhe. Uchungechunge lwe-crane lwe-MAXTECH lwe-AHC (Active Heave Compensation) lusebenzisa ubuchwepheshe bokulawula ukunyakaza ukuze luvumelane nezimo zolwandle ezinzima, okwandisa izimo zokusebenza.
3. Izindinganiso Zokuklama kanye Neziqondiso Ezisebenzayo Zesithende Nokunquma
3.1 Izindinganiso Zokuklama Eziyinhloko
| Isimo Sokusebenza | Isidingo Sesithende | Isidingo Sokunquma | Isimo Esisebenzayo |
| Isimo Sokusebenza Esijwayelekile | ≤5° | ≤2° | Imisebenzi ejwayelekile emachwebeni nasemanzini avikelekile |
| Isimo Sokusebenza Esincishisiwe Umthwalo | 5°–7° | 2°–3° | Izimo zolwandle ezithambile; ukusebenza ngokunciphisa umthwalo ngeshadi lomthwalo |
| Isimo Sokusebenza Esivinjelwe | ＞7° | ＞3° | Izimo zolwandle ezibucayi; kudingeka ukulungiswa kwendlela umkhumbi ocabanga ngayo |
| Isimo Sokugcina Isitoreji Esingasebenzi | ≤30° | ≤10°–15° | Ukuzulazula kwemikhumbi; ukuthwala kwesakhiwo kuphela |
3.2 Imikhuba Yokuklama ye-MAXTECH
- Umklamo Wokuthobela Imithetho: Wonke amamodeli ahlangabezana nemithetho ye-BV ne-CCS, ngaphandle kokunciphisa umthwalo olinganiselwe ngaphansi kwezimo ezijwayelekile. Ukuthembeka komklamo kuqinisekiswa ngokuhlolwa kwamandla amaningi.
- Ukuzivumelanisa Nezimo Ngokwezifiso: Ezifundeni ezikhethekile ezinezinga lokushisa eliphezulu kanye nezimo zolwandle ezinzima (isb., eMpumalanga Ephakathi), izinhlelo ze-hydraulic kanye namandla esakhiwo zilungiselelwe ukuvumela ukusebenza okuzinzile ngaphansi kwezimo ezincishisiwe umthwalo (isithende ≤7°, ukusika ≤3°), ezifanele imikhumbi yesevisi yesikhulumi.
- Ukuvikelwa Kokuphepha: Ifakwe izinhlelo zokulawula kude ezingenantambo kanye nokuvikela ngokweqile ezixwayisa ngokuzenzakalelayo lapho ukuthambekela komkhumbi kusondela emikhawulweni yokuphepha. Ukuhlelwa kwamapayipi e-hydraulic kwenziwa ngcono ukuvimbela ukuvuza kukawoyela okubangelwa ukuthambekela.
4. Isiphetho
Isithende kanye nokusika kuyizinto eziyisisekelo zokuklama i-crane yasolwandle, okuhlobene ngqo nokuphepha kwemishini, ukuthobela imithetho, kanye nokusebenza kahle. Kusukela ekuklanyweni okuhambisanayo ngaphansi kwezimo ezijwayelekile kuya ekuzivumelaniseni nokunciphisa umthwalo ngaphansi kwezimo ezimbi kakhulu, kanye nokwenza ngcono okwenziwe ngokwezifiso kwezimo ezikhethekile, isinyathelo ngasinye kumele silandele imithetho kanye nezidingo ezisebenzayo. Njengoba isithende kanye nokusika kuyizinto eziyinhloko zokuklama, i-MAXTECH ilawula lonke uchungechunge lobuchwepheshe ukuze inikeze amakhasimende omhlaba wonke izixazululo zokuphakamisa ezinokwethenjelwa ezivumelana nezimo ezahlukahlukene zasolwandle, okuqinisekisa indima ebalulekile yalezi zinhlaka ezimbili ekwakhiweni kwe-crane yasolwandle.
