Especially for Dutch contractor Jelle Bijlsma, we have developed a unique innovation: the ‘collapsible’ pontoon YN Touwen. An ingenious hydraulic coupling system makes it possible to narrow the pontoon with machines on board to approximately 5.5 meters. This allows the pontoon to sail through narrow locks and under small bridges. After passing the pontoon is ‘folded out’ again and the work can be resumed immediately. Ideal for example for narrow waters and locks such as in Friesland, the Netherlands.
