NordicTrack treadmills and ellipticals fold up for exactly this reason, but the fold-lock mechanism has to be fully engaged or you risk a fast, heavy drop mid-carry.
Pro tip: Take a photo of the console cable routing before folding, connectors are often hidden and easy to pinch.
Watch out: A fold-lock that releases mid-move can snap the deck down hard enough to break a foot or hand, always confirm the pin or lever is fully seated before lifting.
