Ama-gantries ane-Rubber-tyred (RTGs) kanye nama-cranes asechwebeni anganikeza amandla adingekayo amahhashi kanye nokuguquguquka kokugcina impahla ihamba. Izinto ezihambayo ezihambayo ziza ngezitayela nosayizi abahlukahlukene, kusukela kumaforklift amancane, asebenza ngogesi angalokothi abone ukukhanya kwasemini, kuya ezithwala eziwela, kuya ezinkulu nakakhulu, i-Pneumatic Tyre Gantry ekwazi ukuhamba kufika kumakhilogremu angu-20,000. Ngokuvamile, lezi zingcezu zifakwe amasondo ensimbi okugijima kumathrekhi ensimbi, kodwa i-SEVENCRANE iphinde inikeze amathayi omoya, amasondo enjoloba, namasondo e-polyurethane, imihlangano yesitimela nama-roller.
Kumathayi omoya, ama-transtainer anezinhlobonhlobo zokunyakaza futhi angabizwa nge-RTG, okuyisifinyezo se-Rubber-Tyre Gantry Crane. Ukufanekiswa kwalesi simangalo kufaka phakathi umshini wokuhlinzeka ngamandla kagesi asuka emthonjeni wamandla ngasogwini ukuya kukhreni we-Pneumatic Tire Gantry ngamandla kagesi aphansi uma kuqhathaniswa, ngaleyo ndlela ivumela i-RTG crane ukuthi inqamuke emthonjeni kagesi owodwa wamandla kagesi futhi ixhume kabusha ngomunye umthombo kagesi ohlukile ngaphandle kokuphazamisa ugesi. uxhumano ocingweni lwe-high-voltage. Ucrane omusha we-RTG onenjini kadizili kanye nejeneretha ye-AC kungakhelwa ukusebenza yisikhungo sikagesi esinomphumela we-DC, ngendlela yokuthi ukhreyini we-RTG ukwazi ukwenza imisebenzi yokuwela umzila ngaphandle kwesidingo somthombo wamandla wamandla ombane aphezulu.
Ukuphila isikhathi eside nakho kuwukucatshangelwa okukhulu: amathayi asetshenziswa ezithwalweni ze-port straddle kanye nama-cranes akhathele injoloba ezikhumulweni zemikhumbi, isibonelo, adinga ukufaka izithasiselo ukuze amelane nokudabuka okubangelwa i-UV. Isibonelo, amathayi kuma-gantries akhathele ngenjoloba kudingeka akwazi ukubambelela lapho ethwele imithwalo emikhulu, kodwa akwazi ukuphatha amanani amakhulu wetorque lapho ejika amadigri angu-90 ngenkathi emile.
Ngaphambi kokuthenga i-gantry crane yesondo le-pneumatic, kubalulekile ukucabanga ukuthi uzoyidinga kangakanani ukuze uphakamise umthwalo. Ngaphambi kokuzinza ku-gantry crane yesondo lerabha, qiniseka ukuthi ilungele umsebenzi wakho wamanje kanye neminye engase iqhamuke emsebenzini ofanayo.
