Udonga lwamakhethini luhlanzekile

Le makethe engaba izigidigidi zamadola yokuhlanza udonga lwamakhethini engilazi ibilokhu incike ezindleleni ezintathu zokuhlanza: indoda ejwayelekile ye-centipede, ngentambo, ipuleti nebhakede; Ngokuphakamisa isiteji, ubhasikidi olengayo namanye amathuluzi okuthwala ukuhlanza; Isistimu ye-roof sling rail ihlose i-splicer yefasitela efasiteleni ukuze ihlanzwe. Ezimbili zokuqala ziphansi ngokusebenza kahle, ziphezulu ngomfutho wabasebenzi futhi zisengozini enkulu. Okwesibili izindleko zokusebenza ziphezulu. Uhlobo lwesithathu lokutshalwa kwezimali kokuqala luphezulu, kodwa futhi ludinga ukucabangela uhlelo lokuhlanza amafasitela lapho lwakha, ngakho-ke akulona iqiniso. Njengamanje, okuvame kakhulu emakethe ukuhlanza ngesandla. Umsebenzi wasemoyeni uwumsebenzi oyingozi kakhulu onamaphrimiyamu aphezulu kanye nabantu abaningi abangenawo umshwalense, okusho ukuthi uma kwenzeka ingozi, kunzima ukuqinisekisa amalungelo nezintshisekelo zabo. Izinkampani zesevisi yokuhlanza kanye nabanikazi bezakhiwo nabo bangase babe nemithwalo yemfanelo ehambisanayo. Ayikho idatha etholakala esidlangalaleni mayelana nezigameko zezingozi eziphakeme. Kodwa-ke, kunemibiko yabezindaba yokuthi amashumi ezinkulungwane zezingozi zomsebenzi ezindaweni eziphakeme zenzeka minyaka yonke eChina, phakathi kwazo izinga lokufa lifinyelela ku-80%. Njengoba isizukulwane sangemva kuka-1990 sesiphenduke izisebenzi eziyinhloko, njengemboni esengozini enkulu yokwakhiwa kwezindonga zamakhethini, imboni yomsebenzi wasemoyeni nayo izobhekana nezinkinga zokuqasha. Ngaphansi kwemiphumela embaxambili yokushuba okuphezulu kakhulu komsebenzi kanye nobungozi, igebe lokuqashwa emisebenzini enobungozi kakhulu liyakhula unyaka nonyaka, futhi kuwumkhuba ongenakugwenywa ukubuyisela abasebenzi babantu ngemishini. Kodwa-ke, akulula ukwakha irobhothi elinjalo lokuhlanza ikhethini elisezingeni eliphakeme elingangena esikhundleni somsebenzi wezandla. Kusukela ezidingweni zokuklama zizonke, yebo Hlangana nale misebenzi elandelayo: 1. Umsebenzi we-Adsorption 2. Umsebenzi weselula 3. Umsebenzi wokunqamula izithiyo 4. Umsebenzi wokuhlanza Phakathi kwazo, ubunzima bokusebenza kweselula kanye nomsebenzi wokuwela izithiyo abuphansi. Ubunzima bokusebenza kweselula ukuthi umshini kufanele ukwazi ukuzivumelanisa nezinto ezihlukahlukene zodonga njengefasitela lengilazi yamakhethini, udonga lwensimbi nolwempuphu, futhi ukwazi ukuhamba endaweni egobile nokulawula ukuma. Umsebenzi wokuwela isithiyo udinga ukuthi umshini ukwazi ukuwela ifreyimu yefasitela nezinye izithiyo ngesikhathi sokuhamba, kanti ezinye zazo zidinga nokuqaphela ukuguqulwa kusuka emhlabathini kuya odongeni futhi kusukela odongeni kuya odongeni. Ukuhamba odongeni olugobile kuseyinkinga enzima ukuyixazulula. Ukuxazulula lezi zinkinga, kunezixazululo ezimbili eziyinhloko okwamanje. Enye iwukwenza umshini wendawo yonke, kanti enye iwukwenza amarobhothi ahlukene ezinto ezahlukene. Okwakuqala kuyenzeka ngokwezentengiselwano, kanti lokhu kwakamuva kulula ukukusebenzisa. Eqinisweni, kube nocwaningo lwangaphandle mayelana nerobhothi yokuhlanza amakhethini aphakeme kakhulu, kodwa ayikakhuthazwa kabanzi.
