Notranji portalni žerjav je mostni žerjav, pri katerem je most na obeh straneh podprt z nogami na tleh. Strukturno je sestavljen iz droga, pogonskega mehanizma vozička, dvižnega vozička in električnih delov. Nekateri portalni žerjavi imajo samo na eni strani opornike, druga stran pa je podprta na tovarniški zgradbi ali podstavku, kar se imenuje pol portalni žerjav. Portalni žerjav je sestavljen iz zgornjega mostnega okvirja (vključno z glavnim in končnim nosilcem), opornikov, spodnjega nosilca in drugih delov. Da bi razširili delovno območje žerjava, lahko glavni nosilec sega čez opornike na eno ali obe strani in tvori konzolo. Dvižni voziček z roko se lahko uporablja tudi za razširitev območja delovanja žerjava z nagibom in vrtenjem roke. Portalne žerjave lahko razvrstimo glede na strukturo okvirja vrat, obliko glavnega nosilca, strukturo glavnega nosilca in obliko uporabe.
