Isingeniso kuma-crane avamile echwebeni

Amachweba adlala indima ebalulekile ekwenzeni lula ukuhamba kwezimpahla ezifundeni ezahlukene. Esinye sezici ezibalulekile zechweba ukulayisha nokukhipha impahla ngendlela ephumelelayo nephephile, okudinga ukusetshenziswa kwemishini ehlukahlukene yokuphakamisa. Kulesi sihloko, sibheka eminye yemishini yokuphakamisa esetshenziswa kakhulu emachwebeni, okuhlanganisa ama-gantry crane, abathwali be-straddle, ama-gantry crane afakwe esitimeleni kanye nama-gantry crane anezintambo zerabha.

Enye yezinto ezaziwa kakhulu ngemishini yokuphakamisa emachwebeni yi-gantry crane. Yakhiwe ngama-crane afakwe esakhiweni esihlanganisa ububanzi bonke be-quay. I-crane ingahamba eduze kwesakhiwo ngemizila, ivumele ukuthi imboze izindawo ezinkulu. Njengoba aziwa ngomthamo wawo wokuphakamisa ophezulu, ama-gantry crane avame ukusetshenziselwa ukulayisha nokukhulula imithwalo esindayo emikhunjini.

Izithwali ze-Straddle ziyimishini ekhethekile yokuphakamisa evame ukusetshenziswa kuma-terminal esiqukathi. Zenzelwe ukuphakamisa nokuthutha izitsha, okuvumela ukufakwa kahle, ukususwa kwephalethi kanye nokuthunyelwa kwezitsha ngaphakathi kwe-terminal. Izithwali ze-Straddle zinemilenze elungisekayo edlula imigqa yezitsha, ezivumela ukuthi ziphakamise izitsha ezinhlangothini zombili. Lokhu kuguquguquka kuzenza zilungele ukuphatha osayizi nezinhlobo ezahlukene zezitsha.

Ama-crane e-gantry afakwe esitimeleni, aziwa nangokuthi ama-RMG, aklanyelwe ukuphatha izitsha emachwebeni. Afakwa ezitimeleni futhi angahamba ngokuvundlile eduze kwedokhi futhi aphakamise izitsha ziqonde phezulu. Ama-RMG avame ukusetshenziswa kuma-terminal ezitsha ezenzakalelayo futhi alawulwa izinhlelo zekhompyutha. Lawa ma-crane ayashesha, anembile futhi asebenza kahle ekuphatheni izitsha, okwenza abe yimpahla ebalulekile emisebenzini ematasa yechweba.

Ama-crane e-gantry anezintambo zerabha (ama-RTG) afana nama-RMG ngokuklama nangenjongo. Kodwa-ke, ngokungafani nama-RMG asebenza ezitimeleni, ama-RTG anamathayi erabha avumela ukuthi ahambe ngokukhululeka phansi. Ama-RTG avame ukusetshenziswa ezindaweni zezitsha zokufaka nokuthutha izitsha. Awusizo kakhulu ezindaweni zokugcina lapho kudingeka khona ukushintshwa njalo kwezitsha. I-RTG iguquguquka futhi iyakwazi ukulawuleka ukuze kuphathwe kahle izitsha egcekeni.

Lawa madivayisi okuphakamisa anezinzuzo zawo kanye nezimo zokusetshenziswa. Njengoba enamandla okuphakamisa aphezulu kanye nokufinyelela okubanzi, ama-gantry cranes afanelekela ukuphakamisa imithwalo esindayo emikhunjini. Avame ukusetshenziswa ezindaweni ezinkulu noma ukuphatha imithwalo yephrojekthi emikhulu nesindayo.

Izithwali ze-straddle zenzelwe ukuphathwa kwezitsha ngaphakathi kwedokhi. Amandla azo okuhambahamba emigqeni yezitsha nokuphakamisa izitsha ezinhlangothini zombili avumela ukufakwa kahle kanye nokuthuthwa, okwenza kube ukukhetha okuthandwayo kwama-terminal ezitsha.

Kokubili i-RMG ne-RTG zisetshenziselwa ukuphatha izitsha kuma-terminal azenzakalelayo noma azenzakalelayo kancane. Ukunemba okuphezulu kanye nesivinini se-RMG kwenza ifaneleke ekusebenzeni kwezitsha ezinomthamo ophezulu. Ngakolunye uhlangothi, ama-RTG anikeza ukuguquguquka kanye nokuguquguquka, okuvumela ukuhlelwa kabusha kwezitsha ngendlela ephumelelayo ngaphakathi kwegceke.

Ukuphathwa kwemithwalo okusebenzayo nokuphephile kubalulekile ekusebenzeni kahle kwamachweba. Ukukhetha imishini yokuphakamisa efanele kudlala indima ebalulekile ekwenzeni lokhu kwenzeke. Ama-portal crane, izithwali ze-straddle, ama-gantry crane afakwe esitimeleni kanye nama-gantry crane anezintambo zerabha kumane kuyizibonelo ezimbalwa zemishini yokuphakamisa esetshenziswa kakhulu emachwebeni. Uhlobo ngalunye lunezinzuzo zalo futhi lwenzelwe imisebenzi ethile kanye nezidingo zokusebenza. Intuthuko eqhubekayo kwezobuchwepheshe kanye nokwenza izinto ngokuzenzakalela ikhulise kakhulu ukusebenza kahle kanye nokukhiqiza kwale mishini yokuphakamisa, okuvumela amachweba ukuthi aphathe inani lemithwalo elikhulayo ngempumelelo nangendlela esheshayo.
