Huada Heavy Industry Underslung Movable Scaffolding System (MSS) is delivered to Karachi, Pakistan in August. Upon receipt of all components, on site workers check goods and ready for installation work.
When we count the goods, we should know what the main components of the bridge erector are.
For underslung MSS inner girder system: including steel box girder, nose structure girder, bottom mold and box girder lock system, support structure system, walk device etc. Inner girder system bears most weight of casting concrete and assist outer girder launching.
For underslung MSS outer girder system: include bailey truss girder, bailey truss cross girder, hanging girder, lower hook girder, connecting girder, suspender, bottle jack, connecting rod, front-support girder, upper cross girder, rear-support girder, outer mould and mold structure, longitudinal travelling mechanism. Outer girder system bears concrete box girder flange slab weight and part of concrete weight, it also assist inner girder system launching.

For underslung MSS pier top reserved groove and pier body embedded part: pier top reserved groove size 3.8 m deep, 3 m width, located in the center of pier body.

Hydraulic system: the MSS match 5 sets of hydraulic system, according to its function it can be classified into front-support hydraulic system, rear-support hydraulic system, front pier supporting point hydraulic system and bridge deck longitudinal travelling hydraulic system.

All of the above components form the basis of a cost-effective underslung Movable Scaffolding System.
Today, according to our years' experience, Huada Heavy Industry proves that  MSS for construction of cast-in-situ bridges is cost saving with advantages of optimized design, ease to installation, efficient for bridge construction project. Welcome to Huada Heavy Industry consulting the MSS.
