Janson's Couple Pontoons are designed to be transported by standard trucks. They are lowered into the water by telecrane, using the upper couplers as lifting lugs. Once in the water, the pontoons can quickly and easily be coupled by two engineers without any mechanical aid using an effectively designed coupling system. By using a wide range of auxiliary equipment, such as gangways, bollards, fenders, spud legs, and so forth, the flexibility of the Janson Couple Pontoons can be further enhanced.
The pontoons are made up of rugged welded all around steel frames, equipped with a 6 mm thick cover plate, a 10 mm thick reinforced deck plate and an 8 mm thick reinforced base plate. Links are designed for a resistance of 20 tons in each direction. Outboard motors, pontoons and winches are available for movement of the platforms. Special steerage elements can be used to increase the stability and the surface, using a minimum number of required pontoons in applications where added buoyancy is not required. Janson Coupling pontoons are available in 3 different heights: 1.00, 1.50 and 2.00 metres.
