Moveable Scaffolding System




MSS-S Series Moveable Scaffolding System
(Over Head MSS)


MSS-S Series MSS is a fully self-supporting formwork system that builds the bridges with span-by-span cast-in-situ method; it builds and relocated by itself from span to another span. MSS is very useful when Segmental construction or other cast-in-place methods are not economical or are not possible. MSS can be use for Double-T, Box girder or U-Shape bridges. MSS become most economical when the bridges to be built are below 50 spans.

Over Head MSS is very useful for building cast-in-situ bridges with low pier or varies type of pier. We supply steel formwork alternately timber and plywood sheeting formwork system can be used. We supply mechanical formwork for internal forming if the client needs it. We also supply special solution for double casting procedure on the Box Girder bridges which save times, equipment investments and labors. You are welcome to contact us for detail.

MSS-S Series Moveable Scaffolding System
(Under Slung MSS)


Under-Slung MSS has all the advantages similar to its over head model, except that it gives additional users friendly feature by providing a clear space above the formwork. MSS-S Series Under-Slung MSS is very useful when the bridge designed with monotype of pier; which is normally the case when the bridge is crossing river.

The support condition is customized according designer requirements. We can provide support all the way to the pile cap which leaves no construction mark on the pier or we can make the erection easier by clamping the MSS to the pier and this is the method to be use when the pier is high.
