Iigantries zeRubber-tyred gantries (RTGs) kunye neharbor cranes zinokunika amandla afunekayo ehashe kunye nokuguquguquka kokugcina imithwalo ihamba. Izixhobo zokuhambisa izinto eziphathekayo ziza kwiindlela ezahlukeneyo kunye nobukhulu, ukusuka kwii-forklifts ezincinci, ezinamandla zombane ezingazange zibone ukukhanya kwemini, ukuya kwii-cross-carriers, ukuya kwi-Pneumatic Tire Gantry ekwazi ukuhamba ukuya kwi-20,000 pounds. Amaxesha amaninzi, ezi ziqwenga zixhotyiswe ngamavili entsimbi okuqhuba kwiindlela zentsimbi, kodwa i-SEVENCRANE ikwabonelele ngamavili omoya, irabha, kunye namavili e-polyurethane, iindibano zikaloliwe kunye neeroli.
Kumatayara e-pneumatic, i-transtainers inoluhlu olubanzi lokunyakaza kwaye ingabizwa ngokuba yi-RTG, isifinyezo se-Rubber-Tyre Gantry Crane. Imiboniso yeli bango ibandakanya izixhobo zokubonelela umbane osuka kumthombo wamandla aselunxwemeni ukuya kwicrane yePneumatic Tire Gantry kumbane ophantsi kakhulu, ngaloo ndlela ivumela i-RTG crane ukuba iqhawule kumthombo wombane omnye wamandla ombane kwaye iphinde iqhagamshele kumthombo wombane owahlukileyo ngaphandle kokuphazamisa umbane. uqhagamshelo kwi-high-voltage wire. Ikhreyini entsha ye-RTG ene-injini ye-diesel kunye nejenereyitha ye-AC inokwakhelwa ukusebenza yi-catenary yombane enemveliso ye-DC, efana ne-RTG crane ikwazi ukwenza imisebenzi yokunqumla indlela ngaphandle kwesidingo sombane ophezulu wombane womthombo wangaphandle wokufaka amandla.
Ubomi obude bukwayingqwalasela enkulu: amatayara asetyenziswa kwi-port straddle carriers kunye ne-raber-dired cranes kwi-docks, umzekelo, kufuneka ibandakanye izongezo zokumelana nokukrazula okubangelwa yi-UV. Ngokomzekelo, amathayi kwi-gantries ene-rubber ediniweyo kufuneka ikwazi ukubonelela ukubamba xa ithwele imithwalo emikhulu, kodwa ikwazi ukuphatha ixabiso elikhulu le-torque xa ijika i-90 degrees ngelixa imile.
Ngaphambi kokuthenga i-crane ye-pneumatic tire gantry, kubalulekile ukucinga malunga nokuba uya kuyidinga kangakanani ukuphakamisa umthwalo. Phambi kokuba uzinze kwigantry crane yerabha, qinisekisa ukuba iwulungele umsebenzi wakho wangoku kunye neminye enokuvela kumsebenzi ofanayo.
