Main cycle steps:
• Columns showing the blockouts where to fix the supporting brackets
• When no blockouts can be used we use a saw tooth plate solution or struts to the column foundation

• Suspension gallows is installed at the tip of the previous span and suspends the main girders rear end during casting.
• Two hydraulic cylinders transmit the loads at the rear from the suspension gallows to the deck webs during casting
• During casting, system is suspended at the rear and is supported to the brackets at the front trough the hydraulic cylinders
• Two hydraulic cylinders transmit the loads at front from the main girders to the supporting brackets

• After deck is pre-stressed the MSS can be lowered at the 2 rear and 2 front main hydraulic cylinders
• Transverse beams central connections are removed
• Both MSS halves are then open to the end of the supporting brackets, using the launching wagons
END
Movable Scaffolding System Underslung Solution
MENU
NEXTPREVIOUS
• Both MSS halves can now be launched to the next span using the launching cylinders located at the launching wagons
• Both MSS halves will pass outside the columns
END
Movable Scaffolding System Underslung Solution
MENU
NEXTPREVIOUS
• When both MSS halves reach the longitudinal position at next span system is closed by moving the launching wagons towards the columns and transverse beams are connected again
• MSS is now lifted to the casting elevation using the 2 rear and the 2 front hydraulic cylinders
• Rebar works can start and transport of the internal formwork will be made simultaneous to that operation

Internal Formwork and Rebar works
• The internal formwork doesn’t move together with the MSS main structure.
• The opening and closing internal movements are made hydraulically through an internal formwork transport trolley.
• The internal formwork panels are transported one at a time.
• Diaphragm opening to be big enough to pass

Cambering & Nose adjustment
• Few adjustable screw jacks to be adjusted
• Split the main structure into 3 sections (front nose-main girder-rear nose) and design a unique hinged connection between the parts has made it possible to use the MSS with as small as 200m radius
