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

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
•
optimized design
•
ease of assembly


•

efficient operation
A quick, reliable and economical solution for modern bridge construction

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.

After concreting, curing and tensioning of

cables, the Main Girder and the Transverse
Trusses are lowered by the main jacks at
the rear and front Pier Supports.

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.
