The pivot point between the counterweight pylon and the pendulum is subjected to less stress, which is why a less maintenance-sensitive bearing was chosen in this design: a spherical plain bearing with a fibre-reinforced plastic liner. The fourth variant concerns the pivot point between the pendulum and the approach ramp, where a spherical plain bearing was also used due to the relatively low bearing forces. Just as with the uppermost pivot point, the ends of the axle are concealed behind removable steel covers.
High water resistance
Both hydraulic cylinders of the bridge can be seen and are therefore configured outside of the chamber. From the bridge’s eastern side, the working of the cylinders is clearly visible and can be observed during opening and closing. Should the water level of the Wantij be (incidentally) high, both the chamber floor and the cylinder feet supported by the chamber floor may become submerged. Therefore, the lower cylinder of the award-winning bridge is provided with a special coating suitable for underwater use. In addition, the pivot point on the underside is equipped with a double seal and is filled with grease. The lower cylinder pin will not be negatively impacted if the bridge becomes partially submerged for an extended period.
The architectural design combined with Iv-Infra’s technical elaboration and execution were reason enough to nominate this unique bicycle and pedestrian bridge and ultimately crown it as the winner. •
