Delivery 2 x D280 including cardan under NBD standard
Recently we have delivered two hydraulic cylinders including cardan for a bridge in the province of Zuid-Holland. The cylinders have a bore of ø280mm, a piston rod of ø180mm and a stroke of 2805mm and move the bridge deck of the bascule bridge.
Special about this order are the rod fork produced from one forging and the specially manufactured cardan with pin hole connection. Furthermore, the cylinders are provided with a ceramic coating on the piston rod. The medium used is a biodegradable HEES fluid (Panolin®). The cylinders, manifold and cardan are painted in RAL5010. After we have carried out an internal Factory acceptance test (FAT test) together with the client, they will commission them on site together with the hydraulic unit and control.
These 2 hydraulic cylinders are both delivered under the well-known NBD standards of Rijkswaterstaat. This includes a complete data book including material certificates, welding reports and (strength) calculation documents.
