MSS - Moving Scaffolding System

The MSS was first designed in close co-operation with Norwegian contractors in the 1970's

The system has since then been developed and successfully used in various major bridge projects in Scandinavia and world wide.

The design of our advanced equipment has been improved and optimized over the years, based on our wealth of experience from over 100 projects The system is light weight, easy to assemble, practical in design,

supported by internationally known hydraulic and cranage systems, and most importantly, efficient in operation

Strukturas supplies two types of MSS:

• Overhead MSS

• Underslung MSS

Overhead MSS

The development of our cost-effective system over the years, stems from the need to reduce the high costs of construction manpower in Norway Today, our MSS for cast-in-situ bridges can offer many cost-saving advantages to your bridge construction projects, through:

Overhead MSS for the construction of

Cast in-Situ Bridges

Overhead MSS

The MSS can also easily be adapted to any bridge cross section (single box, double box, double T, etc.) and span configuration This flexibility provides the contractor the opportunity to re-use the equipment from one project to another

NOTE

The first span is usually 0,8 x max span The following

pours will cantilever by 1/5 of the span lengths.

In the next position, the Formwork is

assembled and rigged into place

A Rear Support is rigged in place, and will

provide the lifting of the Main Girder by

means of the two rear hydraulic main jacks

The Suspension Bars are adjusted,

However, no Pier Support will be available

at the rear end of the Main Girder this time
