A Giant Crane Places Steel Bridge Structure at Špica in its Final Position / Most pri Špici v Celju
On 29. November 2024, the steel structure of a new bridge over the Savinja River at Špica was installed in Celje, Slovenia. The bridge steel structure, measuring 76.6 meters in length and weighing 127 tons, was transported from a nearby construction site using a 750-ton mobile crane, lifted, and placed into its final position. The impressive installation went smoothly and attracted numerous spectators to the popular Celje walking and hiking path along the Savinja near the Celje rowing center at Špica. The assembly was carried out by the companies VOC Celje d.o.o. and ŠUŠTERŠIČ d.o.o., while the steel structure was manufactured by BS VAR d.o.o.
The bridge structure was lifted and placed on its final bearings in a single piece, eliminating the need for temporary intermediate supports in the Savinja riverbed. The temporary platform for the crane will be removed in the coming weeks, and the bridge is expected to be completed in the first half of next year. Once finished, it will be the largest bridge structure on the long-distance cycling route connecting Šempeter and Celje.
The bridge, with a span of 76.0 meters, is designed as a simply-supported arch "Vierendeel" girder. The girder’s structural height varies due to the arch-shaped upper chord, ranging from just 1.5 meters at the ends to 6.0 meters at the midspan. The vertical members are spaced 4.0 meters apart and aligned centrically (radially) relative to the curvature of the upper chord. The superstructure's bottom chord is strengthened by a composite Hi-Bond deck-slab, adding also to the dynamic stability of the slender bridge.

Velikansko dvigalo odložilo jekleno konstrukcijo mosta pri Špici na končno mesto
29. novembra 2024 je v Celju potekala montaža jeklene konstrukcije novega mosta čez Savinjo pri Špici. 76,6 metrov dolga in 127 ton težka jeklena konstrukcija je bila s pomočjo 750 tonskega mobilnega avtodvigala prepeljana z gradbišča v neposredni bližini, dvignjena in odložena na končno mesto. Atraktivna montaža je potekala brez zapletov, na priljubljeno celjsko sprehajalno in pohodniško pot ob Savinji pri celjskem veslaškem centru pa je privabila tudi številne obiskovalce. Montažo sta izvajali družbi VOC Celje d.o.o. in ŠUŠTERŠIČ d.o.o., medtem ko so jekleno konstrukcijo izdelali v BS VAR d.o.o.
Mostna konstrukcija je bila dvignjena in postavljena na končna ležišča v enem kosu, zato v strugi Savinje ni bilo treba postavljati začasnih vmesnih podpor. Začasni plato za avtodvigalo bo odstranjen v prihodnjih tednih, most pa bo predvidoma dokončan v prvi polovici prihodnjega leta. Po dokončanju bo največji premostitveni objekt daljinske kolesarske povezave med Šempetrom in Celjem.
Most z razponom 76.0 m je zasnovan kot prostoležeči ločni “Vierendeel” nosilec. Statična višina celotnega nosilca se, vsled ločno napetega zgornjega pasu, spreminja od le 1.5 m na koncih do 6.0 m v sredini razpona. Vertikale so postavljene v razmaku 4.0 m in usmerjene centrično (radialno) glede na zaokrožitev zgornjega pasu. Prekladno konstrukcijo v spodnjem pasu poleg jeklenih nosilcev predstavlja še sovprežna Hi-Bond AB plošča, ki dodatno zmanjšuje dinamične odzive vitke mostne konstrukcije.
