A maneuver smooth and sight relatively simple, repeated seven times, served to realize the framework of the bridge of San Juan. A pedestrian link road, Circle of Peace cemetery costs, now it represents a tangible reality. The preparations, starting with smooth surface that has hosted a large concrete beams, and had a running time. Just as the collection of these moles prefabricated 40 meters long and 54 tons in weight.
Cranes in the San Juan bridge
Finally at dawn Tuesday, with all the congratulations and authorizations, in particular convoy, reached the last two concrete beams, so early in the morning to walk threw the assembly operation of the frame of this long awaited connection which again became fun and unusual show. By total operation, four large cranes Txuri-Urdin colors, emblem of the company from home, Cranes Usabiaga, were traveling on Monday to facilitate the assembly of this structure. Two to meet the work load on the campaign prepared on the side of the entrance to the cemetery, and two on foot stirrup, one on each side of the river Oria. Work of assembling and dismantling the infrastructure, which again required more time than the operation of locating the beams above.
Serve as a detail that the transfer of balances that require two cranes stationed on both sides of the river, called for a transfer, deliver or pick from a low of 25 trucks. Yesterday, however willing, a 500-ton crane, sitting right at the beginning of the slope of the cemetery, serving as the primary device for the operation assisted by the one located in the Polygon. The mechanics of placing seven times was exactly the same. The special truck, a dolly, came running back from the loading point at the entrance to the cemetery. The main crane beam hooked from the end closest to immediately begin to hoist and a 90 degree turn to place it in the air, in a position very close to its final location. So measured, the dolly, stripped the car back, down the hill to reach the height of the crane to allow this rotation.
With the skewer and subject beam and in the air for that one extreme, a worker came to change the tie, something which was now subject to the auxiliary crane. Main crane was going to hook the tip still stood by the cab of the truck, which is now subject to both vertices was installed in her rightful place in the stirrup. Except with the first, who served as a test, the maneuver needed on average an hour to install each beam. At 1 pm was placed fourth.
After lunch resume the task, keeping the same pattern of operation, and measured pace, left in place for 5.30 pm, ahead of schedule, the seventh and final beam.
Road open to traffic
Which allowed work to begin immediately with the removal of heavy machinery in order that today in the morning the road is again open to traffic.
Among the views expressed by the crowd, which gathered at the site during the sunny morning, the one who excelled understood that as things stand, it was hoped that once the legendary bridge open to traffic (expected in early summer) did not have to pay a toll to cross from one river to another.
