Abstract : A portable personnel platform and ladder for use with elevated piers and floating decks has one end of a compression framework pivotally attached to a rope ladder supporting platform which extends over the pier's edge; adjustable wire backstays which provide cantilever strength connect the opposite end of the compression framework to the upper end of railings on the ladder supporting platform. The opposite end of the compression framework is adapted to have weight added thereto or to be secured to the pier deck. The length of the compression framework is such that considerable leverage is provided to support the weight of several people climbing on the rope ladder attached to the supporting platform while using much less counter-balancing force on the opposite end of the compression framework.
