FIELD: ferrying and bridging facilities. SUBSTANCE: this particularly relates to ferries and floating bridges. Pontoon link has two middle pontoons and two extreme pontoons pivotally connected to each other, tipping gangboards which in folded position create level carriage way of bridge, interlink joining units made in he form of yoke with locking stem and eye-lug. Installed on bot sides of pontoon link are load-carrying beams with drawbars. At one side of pontoon link, side beams are made with sledge configuration, and interlink joining units are installed in recesses flush with sledge configuration. At using pontoon link in floating part of bridge, load-carrying beams can be pivotally attached to eye-lug and yoke. Load-carrying beams at other side are ending respectively in yoke and eye-lug. In this case, secured on each load-carrying beam is drawbar which by its other end is secured to deck load-carrying beam by stem-type lock. Pontoon link is of higher load-carrying capacity and improved streamline trimming when moving with its shore-end forward, thus reducing resistance to movement. EFFECT: higher efficiency. 1 cl, 7 dwg øøø1 |
