Crane yeGantry Crane chishandiso chakakosha chakagadzirirwa kuvaka mabhiriji, viaducts nezvimwe zvivakwa zvakakwirira. Inoshandiswa kusimudza nekuisa mabhiriji ekongiri kana esimbi akaiswa panzvimbo yayo kuti dheki rikurumidze kubatanidzwa. Crane dzeGantry dzinowanzo kuve nefuremu yakasimba inotsigirwa nema outriggers anotenderera hupamhi hwebhiriji. Yakashongedzwa nenzira yekusimudza nemazvo inogona kusimudza mabhiriji anorema nemazvo uye nemazvo.
Basa guru re crane ye launch gantry nderekubatsira kufamba kwakatwasuka uye kwakatwasuka kwe bhiriji panguva yekuvaka. Izvi zvinoitwa kuburikidza nekusanganiswa kwema hydraulic, mechanical uye electronic systems anoshanda pamwe chete kuti ave nechokwadi chekuti mashandiro akanaka uye anodzorwa. Kugona kwe crane kufambisa zvinhu zvinorema nemazvo kunoita kuti ive chishandiso chakakosha pamapurojekiti ekuvaka bhiriji, zvichideredza zvakanyanya nguva nebasa rinodiwa kuti chivakwa chipedzwe.
Chimwe chezvakanakira zvikuru zvekushandisa crane yekutanga kugona kukurumidzisa nguva yekuvaka. Nekuisa bhiriji rakagadzirwa kare nekukurumidza, macrane anogona kukurumidza kuunganidza deki, zvichideredza kukanganiswa kwemotokari uye kupfupisa nguva yepurojekiti yese. Izvi hazvingobatsiri kambani yekuvaka chete mukuchengetedza nguva nemari, asiwo zvine simba rakanaka kune nharaunda yakapoteredza nekuderedza kusagadzikana kunokonzerwa nekuvaka.
Kuchengetedzeka chimwe chinhu chakakosha pakuvaka mabhiriji, uye kushandiswa kwemacrane ekusimudza magantry kunovandudza zvakanyanya kuchengetedzeka panzvimbo dzekuvaka. Nekuderedza kudiwa kwekubata mabhiriji anorema nemaoko, njodzi yetsaona nekukuvara inogona kuderedzwa zvakanyanya. Masisitimu ekudzora epamberi ecrane uye maficha ekuchengetedza anovimbisa kuti kusimudza nekuiswa kwematanda kunoitwa nemazvo uye zvichienderana nemitemo yekuchengetedza.
Kugona kwayo kugadzira ma "gantry cranes" kunoitawo kuti ive chinhu chinokosha pakuvaka mabhiriji.

Ingava nzira yepamusoro-soro, bhiriji rechitima kana nzira yekufamba, ma "launch gantry cranes" anogona kugadziriswa zvichienderana nezvinodiwa zvepurojekiti.
Muchidimbu, kutanga ma gantry cranes kunomiririra kufambira mberi kukuru muhunyanzvi hwekuvaka mabhiriji, zvichipa kushanda zvakanaka, kuchengetedzeka uye kushanduka-shanduka. Kugona kwayo kukurumidzisa maitiro ekuvaka, kuvandudza mitemo yekuchengetedza uye kugadzirisa zvinodiwa zvakasiyana-siyana zvepurojekiti kunoita kuti ive chishandiso chakakosha kumapurojekiti ekuvaka emazuva ano. Sezvo indasitiri yekuvaka ichiramba ichichinja, kuunzwa kwema gantry cranes kunoratidza simba rekuvandudza kufambira mberi uye kushandura maitiro atinoita kuvaka zvivakwa zveramangwana.
