The ribbon bridge *9A is a kind of heavy pontoon equipment used for constructing *0tf and *0tf floating bridge and *0tf, *0tf and **0tf ferry rafts over rivers with a current velocity not higher than 2.5m/sec. One complete set consists of *4 interior bays, 2 ramp bays, 5 erection motor boats and *1 refitted cross-country transporters.
Main features of the equipment are: The floating bridge and ferry raft, constructed from the tight-boxes integrating pontoons, stringers and plates, being continuous ribbon-type floating bodies; An easy conversion between floating bridge and ferry raft, as each interior pontoon (or shore pontoon) being a section of a floating bridge or a ferry raft with the same structure; A wide roadway used as either a single-lane for heavy loads or a double-lane for light loads;  No wharf construction required in raft crossing, its accompanied ramps facilitating loading and unloading after mooring.
