Vnútorný portálový žeriav je mostový žeriav, v ktorom je most podopretý na pozemnej dráhe nohami na oboch stranách. Konštrukčne sa skladá zo stožiara, ovládacieho mechanizmu vozíka, zdvíhacieho vozíka a elektrických častí. Niektoré portálové žeriavy majú podpery iba na jednej strane a druhá strana je podopretá na továrenskej budove alebo kozlíku, ktorý sa nazýva poloportálový žeriav. Portálový žeriav sa skladá z horného mostného rámu (vrátane hlavného nosníka a koncového nosníka), podpier, spodného nosníka a ďalších častí. Aby sa rozšíril prevádzkový rozsah žeriavu, hlavný nosník môže presahovať za podpery na jednu alebo obe strany a vytvoriť tak konzolu. Zdvíhací vozík s výložníkom možno použiť aj na rozšírenie pracovného dosahu žeriavu nakláňaním a otáčaním výložníka. Portálové žeriavy možno klasifikovať podľa konštrukcie rámu dverí, tvaru hlavného nosníka, štruktúry hlavného nosníka a formy použitia.
