APPLICATION RANGE AND USEHIDE/SHOW

MSS downstroke movable support system bridge making machine is bridge construction equipment using methods of cast-in-situ and span by span construction, designed to meet  continuous box girder construction.

The downstroke movable support system adopts support under the bridge deck, uses two groups of steel box girder to support pattern plate, and realizes the complete machine to move laterally and longitudinally to cross piers by main girder bringing with formwork and pattern plate. Equipped with 3 sets support legs, as starting pouring concrete beam, two sets legs as support, before crossing piers, the third set leg moves backward to be installed on pier at front of it, meeting the demand of crossing piers, span by span construction, moving backward repeatedly. The movable support system is equipped with 4 sets hydraulic systems to realize automatic jacking of formwork, lateral moving and longitudinal moving.

MAIN FEATURES AND ADVANTAGESHIDE/SHOW

The machine is installed below the bridge floor, supporting the templates with two sets of steel box girder. The moving between the piers is carried through the transverse moving and longitudinal traveling of the main girder mould bases with the template. With three sets of support legs, two of them is used to supporting while casting the concrete girder. As the machine needs to move from one pier to next pier, the third support leg shifts to the front pier and fix on it in order to accomplish the task. The moving method of the machine is like this, one by one. Equip with four sets of hydraulic system, the machine can realize the jacking up, transverse and longitudinal traveling automatically.
