Double girder bridge crane inoumbwa nematanda maviri emabhiriji anonamirwa panjanji, uye anowanzo kupihwa epamusoro emagetsi tether-rope trolley lifts, asi anogona kupihwawo pamusoro pemagetsi cheni yekusimudza zvichienderana nekushandisa. SEVENCRANE Overhead Cranes uye Hoists inogona kupa akareruka girder bhiriji cranes kuti ishandiswe zvakajairika, uye zvakare inopa yakavakirwa kaviri girder bhiriji cranes kune akasiyana maindasitiri. Kaviri girder bhiriji crane inoshandiswawo mukati kana kunze, kungave pamabhiriji kana mugantry masisitimu, uye inowanzoshandiswa mumigodhi, simbi nesimbi kugadzira, njanji mayadhi, uye zviteshi zvegungwa.
Double girder Bridge crane inowanzoda kucheneswa kukuru pamusoro peiyo crane runway kukwirisa sezvo marori anosimudza achipfuura nepamusoro pebhiriji girder. Single-girder cranes inopa nzira dziri nani kune ese ari maviri ekusimudza uye rwendo rwebhiriji pane maviri-girder cranes. Kunyangwe zvisingawanzo kuoneka, bhiriji regirder riri pasi-rinomhanya crane rinogona kupihwa nepamusoro-inomhanya trolley hook. Madhiriji emabhiriji maviri ane mapango maviri emabhiriji anonamirwa panjanji, uye anowanzo kupihwa tambo dzepamusoro dzine tambo dzematrolley dzinofambiswa nemagetsi, asi dzinogona kupihwa macheni epamusoro anofambiswa nemagetsi zvichienderana nekushandisa.
Kushandisa ikozvino computational systems, SEVENCRANE Double Girder Overhead Cranes inogona kugadzirisa uremu hwavo kuitira kuderedza masimba akaiswa pachigadziro nemitoro yavo, uyewo achivandudza kusimudza kugadzikana kwechigadzirwa panguva yekutakurwa kwehuwandu hukuru hwekutakura. Sezvo bhiriji crane spans uye hunyanzvi hunowedzera, magidhi akatambanudzwa anozowedzera kudzika kunodiwa (kureba kwegirder) uye huremu parutsoka. Chimiro cheiyo bhiriji-yakaiswa pamusoro-yekufamba crane ndeyekuti marori anomhanya nemavhiri pasi kureba kwetrack system, ane bhiriji-cable girder yakaiswa parori yekupedzisira, uye marori emabhoom akamisa mabhoom, anofamba pamusoro. iyo span. Overhead cranes neGH Cranes & Components anowanikwa mune maviri masitaera, bhokisi-girder uye akajairwa maprofiles, uye akashongedzerwa neakavakirwa-mukati mechanisheni yekusimudza, kazhinji ingave yekusimudza kana yakavhurika-inopera.
