Rubber-tyre container gantry cranes, inowanzonzi RTGs muchidimbu, inoshandiswa kurongedza midziyo pamayadhi emidziyo. Iyo inodaidzwa zvakare semudziyo wekutakura midziyo, inogona kupfupikiswa seRTG crane, inoshandisa matayi erabha kufamba pamayadhi anotakura zvinhu, inhare yegantry crane inowanzo shandiswa kurongedza midziyo, madoko, uye kumwewo. RTG crane inhare yerabha tyred gantry crane, inowanzo fambiswa nedhiziri-jenareta sisitimu kana imwe magetsi ekupa magetsi, uye imhinduro yakanaka kubata midziyo ine mwero.
rtg mudziyo unopa kuita kwakakura uye kuvimbika mumidziyo yekuisa. Kwete kungofamba uchitenderedza doko rekurodha, rtg mudziyo unobvumidzawo kudzoreredzwa kwemidziyo uye kushanda nesimba. Universal-mhando RTG crane chinhu chakakosha chidimbu chemidziyo yechiteshi chemidziyo.
rtg mudziyo unokodzera kutenderera midziyo mishanu-masere uye kusimudza marefu kubva pamusoro pe3-kusvika 1-pamusoro-6 midziyo. Rubber-tyreged container (RTG) cranes inogona kupihwa muhupamhi hwemapapiro mapiko kubva kumashanu kusvika kumasere emidziyo yakafara (pamwe nehupamhi hwemarori ematinji), uye nekusimudza marefu kubva pa1 pamusoro pe3 kusvika 1 pamusoro pezvitanhatu. Mumufananidzo uri pamusoro apa, maviri Rubber Aneta Pamusoro Pemusoro Cranes (RTGs) ari kushandira stack.
Chinangwa chegantry crane chakaiswa mugaba ndechekuisa midziyo mumutsara wekurongedza. Automated Rail-mounted Gantry Cranes (ARMGs) yakave yakakurumbira kubva payakavambwa panzvimbo itsva-yekuvaka zviteshi, uko midziyo yekuvaka yakatarisana nechiteshi inobatsira, uye nzvimbo dzekuchinjisa dziri kumagumo emayuniti. Dhizaini yakakurumbira yekutsinhana inoshandisa maviri akafanana ARMG cranes pamudziyo wega wega block, ichimhanya ichitevedza track imwechete ine yakajairika nzvimbo yekushanda (ona mufananidzo 1). Otomatiki midziyo yekubata matekinoroji yakasimukira nekukurumidza, iine tarisiro yekuve macranes anogadzirisa epakati kuchengetwa kwemidziyo mukati meyadhi.
Nekuda kwekushaikwa kwegetsi remagetsi rekurasa simba sezvo midziyo iri kudzikiswa, maRTGs anowanzo ratidza mahombe ekupikisa ekukurumidza kubvisa simba kubva mumidziyo yakadzikiswa kana inononoka. Kana accumulator ikashandiswa, iyi inogona kuiswa panzvimbo dzakasiyana pasi pemidziyo inotsvedza kuitira nyore RTG bhatiri kuwana.
