Kwiimeko zokusebenza elwandle, ii-cranes zaselwandle zisebenza njengezixhobo eziphambili zokulayisha/ukukhulula. Ukusebenza kwazo ngokukhuselekileyo nangokufanelekileyo kuxhomekeke ekuziqhelaniseni ngokuchanekileyo neemeko eziguquguqukayo zeenqanawa —isithende kunye nokuchebaziiparameter ezibalulekileyo zoyilo ezimisela ngokuthe ngqo amandla olwakhiwo, umthamo womthwalo, kunye nokuzinza kokusebenza kweekhreyini.I-MAXTECH, umenzi weekreyini zaselwandle odumileyo kwihlabathi liphela, umzekelo, inkampani ifaka iimfuno zesithende kunye ne-trim kwimigangatho yoyilo oluphambili lomgca wayo opheleleyo wemveliso. Ngolawulo oluphindwe kabini lokuthobela kunye nokusebenza, i-MAXTECH iqinisekisa ukhuseleko lokusebenza phantsi kweemeko ezahlukeneyo zolwandle.
1. Iinkcazo eziphambili zesithende kunye ne-Trim
1.1 Isithende
Isithende sibhekisa kwindlela enqamlezileyo yomkhumbi ojikeleze i-axis yayo yangaphambili neyasemva, oko kukuthi, umahluko wokuphakama phakathi kwamacala e-port kunye ne-starboard, olinganiswa ngamadigri (°). Okubangelwa ngumoya, amaza, okanye ukulayisha/ukukhulula imithwalo engalinganiyo, isithende sichaphazela ngokuthe ngqo umgangatho wee-crane booms kunye nokususwa kwamaziko omthwalo womxhuzulane, okusebenza njengophawu oluphambili lokuzinza kwe-crane ecaleni.
1.2 Ukucheba
I-Trim ibhekisa ekuthambekeni okude kwenqanawa malunga ne-axis yayo enqamlezileyo, oko kukuthi, umahluko wokuphakama phakathi kwesaphetha kunye nomva, olinganiswa ngamadigri (°). Ibangelwa kukutshintsha kobunzima benqanawa, ukuphosa okubangelwa ngamaza, okanye ukutshintsha kwesikhundla somthwalo, i-trim itshintsha i-engile ye-pitch yee-crane booms kunye nokusasazwa komthwalo okude, okuchaphazela ibhalansi yamandla ee-boom kunye neziseko.
Iinqanawa zisebenza ngokuqhubekayo phantsi kweemeko zesithende kunye nokulungiswa elwandle. Zidibene nemithwalo enamandla evela kwimisebenzi yokuphakamisa, oku kubeka izinto ezibalulekileyo zekreyini (umz., iziseko, ii-boom, kunye neebheringi ze-slewing) kwiingcinezelo ezidibeneyo. Ngaphandle koyilo olubala ii-angles zokuthambekela, izakhiwo zinokutshintsha, ziqhekeke, okanye zilahlekelwe kukuzinza. Xa kuyilwa iikreyini zayo zasemanzini ze-knuckle boom kunye ne-telescopic boom, i-MAXTECH yenza uhlalutyo lwezinto ezilinganiselweyo ngokusekelwe kwii-angles zokuthambekela ezisemgangathweni ukuqinisekisa ukuba ii-boom, ii-pins, iipayipi ze-hydraulic, kunye nezinye izinto ziyahlangabezana neemfuno zamandla phantsi kwengcinezelo edibeneyo.
2.2 Ukuhlangabezana neeMfuno zoLawulo zoQinisekiso lokuThotyelwa kweMithetho
Iikhreyini zolwandle kufuneka zifumane iziqinisekiso ezivela kwimibutho ephambili yokwahlulahlula efana neCCS, BV, kunye ne-ABS.isithende esingu-≤5° kunye ne-trim engu-≤2°yimeko yokusebenza esemgangathweni edibeneyo kwihlabathi liphela. Umzekelo, i-IMO MSC.1/Circ.1477 icacisa ukuba ii-cranes mazisebenze ngokukhuselekileyo kumthwalo opheleleyo phantsi kwesithende esili-5° ngaxeshanye kunye ne-trim ye-2° kwimisebenzi yezibuko. I-China Classification Society (CCS)Imithetho yezixhobo zokuphakamisa iinqanawa kunye nokufakelwa kwamanye amazweikwasebenzisa ezi engile njengomlinganiselo wokubala uMthwalo wokusebenza oKhuselekileyo (SWL). Iimveliso ze-MAXTECH zithobela ngokungqongqo le migaqo ukuze zifikelele kwiimarike zehlabathi zaselwandle.
2.3 Ukuziqhelanisa neemeko zolwandle ezintsonkothileyo ukuze kwandiswe ububanzi bokusebenza
Ngokwesiqhelo, iinqanawa zinokudlula iimeko zokusebenza eziqhelekileyo ngenxa yeemeko zaselwandle, nto leyo ebangela ukuba isithende sibe yi-5°–7° kunye ne-trim ye-2°–3°. Kwiimeko ezinjalo,uyilo lokunciphisa umthwalo othambekeleyoiyadingeka ukugcina imisebenzi ngokukhuselekileyo. Ukuba isithende sidlula i-7° okanye i-trim idlula i-3°, ukuphakamisa kufuneka kumiswe kwaye i-ballast yenqanawa ilungiswe. Uthotho lweekreyini ze-MAXTECH ze-AHC (Active Heave Compensation) zisebenzisa itekhnoloji yokulawula intshukumo ukuze zilungelelanise neemeko zolwandle ezinzima, nto leyo eyandisa ngakumbi iimeko zokusebenza.
3. Imigangatho yoYilo kunye neMigaqo eSebenzayo yeSithende kunye neTrim
3.1 Imigangatho yoYilo oluPhambili
| Imeko Yokusebenza | Imfuneko yesithende | Imfuneko yokuHlunga | Imeko Esebenzayo |
| Imeko Eqhelekileyo Yokusebenza | ≤5° | ≤2° | Imisebenzi yesiqhelo kumazibuko nakumanzi akhuselekileyo |
| Imeko Yokusebenza Encitshisiweyo Yomthwalo | 5°–7° | 2°–3° | Iimeko zolwandle ezithambileyo; ukusebenza ngokunciphisa umthwalo kwitshathi nganye yomthwalo |
| Imeko Yokusebenza Engavumelekanga | ＞7° | ＞3° | Iimeko zolwandle ezimandundu; kufuneka kulungiswe indlela esijongana ngayo isikhephe |
| Imeko Yokumisa Izinto Ezingasebenziyo | ≤30° | ≤10°–15° | Ukuhamba ngenqanawa; ukuthwala ulwakhiwo kuphela |
3.2 Iindlela zoYilo ze-MAXTECH
- Uyilo lokuthobela imithetho: Zonke iimodeli ziyahlangabezana nemigaqo ye-BV kunye ne-CCS, ngaphandle kokunciphisa umthwalo olinganisiweyo phantsi kweemeko eziqhelekileyo. Ukuthembeka koyilo kuqinisekiswa ngovavanyo oluninzi lwamandla.
- Uhlengahlengiso Olulungiselelwe Ngokwezifiso: Kwimimandla ekhethekileyo enamaqondo obushushu aphezulu kunye neemeko ezinzima zolwandle (umz., uMbindi Mpuma), iinkqubo ze-hydraulic kunye namandla olwakhiwo zilungiselelwe ukuvumela ukusebenza okuzinzileyo phantsi kweemeko ezincitshisiweyo zomthwalo (isithende ≤7°, i-trim ≤3°), ezifanelekileyo kwiinqanawa zenkonzo yeqonga.
- Ukhuseleko loKhuseleko: Ixhotyiswe nge-remote control engenazingcingo kunye neenkqubo zokukhusela ukugqithiswa kwemithwalo ezilumkisa ngokuzenzekelayo xa ukuthambeka kwenqanawa kusondela kwimida yokhuseleko. Uyilo lwemibhobho ye-hydraulic lulungiselelwe ukuthintela ukuvuza kweoyile okubangelwa kukuthambeka.
4. Isiphelo
Isithende kunye nothango zizinto eziyimfuneko ezibalulekileyo kuyilo lwekreyini yolwandle, ezinxulumene ngqo nokhuseleko lwezixhobo, ukuthobela imithetho, kunye nokusebenza kakuhle. Ukususela kuyilo oluhambelanayo phantsi kweemeko eziqhelekileyo ukuya kuhlengahlengiso lokunciphisa umthwalo phantsi kweemeko ezinzima, kunye nokwenza ngcono ngokweemfuno ezikhethekileyo, inyathelo ngalinye kufuneka lilandele imigaqo kunye neemfuno ezisebenzayo. Njengoko isithende kunye nothango zizinto eziphambili zoyilo, i-MAXTECH ilawula lonke uthotho lwetekhnoloji ukubonelela abathengi behlabathi ngezisombululo zokuphakamisa ezinokuthenjwa ezihambelana neemeko ezahlukeneyo zaselwandle, iqinisekisa indima ephambili yale parameters mibini kuyilo lwekreyini yolwandle.
