•    2 vertical lift gates                 (W = 25m x H = 16m)
•    2 vertical lift gates                (W = 25m x H = 9.50m)
•    2 vertical lift gates                  (W = 12.5m x H = 7m)
•    2 Mitre gate pairs                 (W = 25m x H = 16.5m)
•    2 Mitre gate pairs                (W = 25 m x H = 9 m)
•    2 Mitre gate pairs                (W = 12.5 m x H = 7 m)
•    16 culvert gates                (W = 3m x H = 4m)

Total Weight approximately 3.100 ton

All gates are equipped with modern hydraulic drives and electrical controls. Furthermore the repair of ship arrester systems, bascule bridges and other equipment.
