Morphology
Jacob's + ladder
The constituent 'ladder' makes clear this is some kind of ladder, but the possessive proper name 'Jacob's' does not transparently indicate the specific form (a hanging rope or chain ladder) or nautical use. The phrase is a conventionalized name for a particular type of ladder, so a B1 learner would guess it's a ladder but would not reliably infer the precise meaning or form without prior exposure.
Etymology
Jacob's ladder is a hanging rope ladder named after the Bible story where Jacob saw a ladder reaching to 'heaven'; because the ladder has many rungs in a row, sailors and others used that name for a simple hanging ladder.
