Abstract
Abstract A maintenance device for use underneath a deck has an elongated arm connectable to the deck and extending beneath the deck and movable about a vertical axis. A platform mounted on the arm is movable along the arm and may be further movable relative to the arm such as by being rotatable about a second vertical axis or movable vertically relative to the arm. A deck including such a maintenance device may have a plurality of connecting points spaced about the deck such that the arm, by being connected to different ones of said connecting points can reach the entire area beneath the deck.
