This time, the bascule Bridge in Harbour Leixöes, after more than 6 years of operation, has had to replace the Radial Spherical Plain Bearing of the North Leaf.
ARCEN through its sister company EUROCRANE has engineered all the technical procedures, operations and tools to complete the operation.
In record time, all the equipment was supplied in 1 week, with LARZEP providing power packs and 4 single acting lock nut cylinders STX22004, 220 ton and 45mm of stroke that were used to hold the bascule leaf of 600 ton in vertical position, under the leaf in reinforced locations.
A precise operation to release the load on the rotation shaft and spherical bearing, was successfully achieved by the precise stroke and load control of the cylinders. Finally the bearings were replaced.
The operation took 2 days and the equipment will be used in future operations to replace the bearings of the South Leaf.
