Bitandukanye na gari ya moshi yashizwemo gari ya moshi ifite inzira zihamye, reberi tyred gantry crane ni ubwoko bwa gantry crane igendanwa ikoresha reberi ya reberi mu ngendo, bigatuma ibikoresho bikora neza, bikora neza, kandi bifite umutekano.
Birashobora kuba reberi yometse kuri kontineri ya gantry ikoreshwa ku cyambu cyawe, icyuma kigendanwa gikoreshwa mu bikorwa byo guterura ubwato cyangwa crane igendanwa iremereye cyane kubikorwa byawe byo kubaka. Ibikoresho byo mu bwoko bwa reberi byateguwe neza, bikora neza, kandi bikabungabungwa byoroshye, hamwe namabwiriza ahagije yumutekano hamwe nibikoresho birinda imitwaro birenze urugero byumutekano wibikorwa nibikoresho byiza. Crane itandukanye ya RTG irashobora gukorera ahantu hanini kandi yoroheje, ifite ibiranga nkigipimo kinini cyo gukoresha umwanya, imikorere ihanitse, hamwe na moteri yuzuye.
Crane ya RTG irashobora kongera igipimo cyimikoreshereze yububiko, igatwikira ahantu hanini ho guterura, kwimuka. Ntabwo ugenda unyuze hejuru yikigo, RTG irashobora kandi kugera kubikorwa byimashini byoroshye. Crane ya RTG ikwiranye no kuzenguruka ibintu bitanu-umunani no kuzamura uburebure kuva hejuru ya 3 kugeza kuri 1-hejuru-6. Hamwe niterambere ryihuse mubyoherezwa muri kontineri ku isi, uburyo bwo kugemura bugufi, Granry-tyred gantry cranes (RTG cranes) hamwe na gari ya moshi zashyizweho na gari ya moshi (RMG cranes) zikoreshwa cyane mukibuga cya kontineri, hamwe na crane nziza ya RTG hamwe na RMG irasabwa byinshi n'abakoresha.
Bitewe no kugenda kwa rubber tyred gantry crane, reber tyred gantry crane irashobora kwimurwa ahantu hitaruye hanyuma igakoreshwa mugupakira cyangwa gupakurura ibintu biva mumato menshi.
