Portalni žerjav na tirnicah (RMG) je vrsta portalnega žerjava. Njegova kovinska struktura je podobna portalu, z dvema nogama, nameščenima pod glavnim nosilcem, kar mu omogoča, da hodi neposredno po stezi na tleh. Na obeh koncih glavnega nosilca so lahko previsni konzolni nosilci. Portalni žerjavi na tirnicah (RMG) so izdelani po individualnih zahtevah kupcev in so na voljo v različnih višinah in razponih zlaganja.

Rail mounted gantry crane is a type of lifting equipment that is installed horizontally in workshops, warehouses and yards for material lifting. Because its two ends are located on tall concrete columns or metal supports, the bridge of the gantry crane runs longitudinally along the tracks laid on both sides of the elevated frame.

 Rail mounted gantry cranes,also known as RMG cranes,are essential pieces of equipment used in various industries for efficient material handling. These cranes are commonly found in ports, intermodal terminals, and manufacturing facilities.

Pri avtomatiziranih portalnih žerjavih z gumijastimi kolesi SEVENCRANE je tehnologija pozicioniranja dvigala in dvižnih vozičkov zelo pomembna vsebina. V normalnih okoliščinah se delovanje velikih in majhnih tovornjakov kontejnerskih portalnih žerjavov samodejno zaključi z zanašanjem na tehnologijo pozicioniranja. Krmilnik mora le upravljati opremo. Situacijo je možno spremljati preko videa. Za razliko od končne faze dvigovanja, ki zahteva človeško posredovanje, avtomatizacija pozicioniranja velikih in majhnih vozil zahteva večjo tehnično zanesljivost in natančnost.
