Delivery of hydraulic cylinders for the Great Belt Link

The tender procedure concerns the award of a contract regarding purchase of 13 hydraulic cylinders for the Great Belt Link where a refurbishment and partial replacement of the “West Bridge” bearings, 276 in all, is imminent. The project is split into two separate phases, where a test lift in the fall of 2024 is next. The hydraulic cylinders included in this tender shall be used for this test lift. Hence, delivery time is an important part of the delivery. The hydraulic cylinders must have a lifting capacity of minimum 750 tons and comply to strict geometrical restraints, in order to allow for transport out to the piers and be able to place the cylinders within the available clearance between the pillars and the bridge girder. The hydraulic cylinders will be placed in a specially designed steel structure, to act as a side restraint and temporary bearing, which further adds to the strict geometrical restraints. Besides the hydraulic cylinders, the tender also concerns the purchase of a compatible pumping and motion control unit and hoses. The tender also includes options in regard to purchase of additional 8 smaller hydraulic cylinders with a lifting capacity of 50 tons compatible with the offered pumping and control unit as well as an option for on-site assistance/introduction. All requirements for the hydraulic cylinders, pump, motion control etc. are stated in “Appendix 6 – Technical Specifications”.
