Mphepete mwa gombe-gombe, yomwe imadziwikanso kuti ma quay a craidges kapena ofunika kutsitsa zida zotsitsa ndi zida zogwirizira pamtunda ndipo nthawi zambiri zimakhala padongosolo la doko. Ntchito yawo yayikulu ndi kutsitsa ndikutsitsa katundu kuchokera ku zombo zonyamula zinyalala, ndikuwonetsetsa kuti kuyenda kotetezeka komanso koyenera.
Zosiyana ndi ma quay cranes, matabwa a ntradi, imadziwikanso kuti chidebe cham'malire, chimapangidwa makamaka kuti chikutsegulira mayadi. Mtundu wofala kwambiri wa crane ndi crane yokhazikika ya njanji (RMG), makina apadera ogwiritsidwa ntchito mu mayadi. RMGS imagwiritsa ntchito mawilo othamanga pa njanji kuti ikweze ndi zotsekemera ndipo zimakhala ndi mafayilo othamanga 40 ndi 40 kuti agwirizane ndi minyewa yazikulu zosiyanasiyana.
Poyerekeza ndi kakwata kakang'ono kwambiri kwa mphira (RMGS), RMGS imapereka zabwino zingapo. Choyamba, amagwiritsa ntchito magetsi amagetsi ngati gwero lamphamvu, kuthetsa kuipitsidwa kwa mafuta komanso kukhala ochezeka. Chachiwiri, amatha kukulitsa kukweza mphamvu ndi kuthamanga, kukonza kukonza ndikutsitsa bwino. Kuphatikiza apo, Trolley ya RMG imatha kuyenda mwachangu pomwe ikukweza katundu, kulimbikitsa kuthamanga kwa ntchito ndi kusinthasintha.
Mwachidule, quay Cranes ndi Yard Craces amatenga gawo lofunikira mu chidebe ndi mayadi. Sikuti amangosintha kukonza ndikutsitsa bwino komanso kutsimikizika chitetezo komanso zachuma.
