Because the platforms center of gravity is still kept off the equilibrium position then the restoring gravity force acts continuously like pushing the platform towards the bridge -that pushing force firmly stabilizes the platform against the bridge. The above described swing back is prevented by the use of adjustable bumpers, keeping the distance between the platform and the bridge structure. the second position is when counterweight is intentionally displaced in such way, that the whole platform center of gravity is moved away from the equilibrium position then the ever present gravity force induces the unavoidable attempt to swing platform back to restore the equilibrium (center of gravity under the suspension points).first one - when the counterweight location helps to maintain the whole platform center of gravity exactly under suspension points and it keeps the free hanging platform in the equilibrium state.There are two important positions of this movable counterweight: The intentional movement of this counterweight changes the position of gravity's center of the whole suspended platform - the platform therefore is able to make the small, controlled swing movement in respect of its suspension plane. In SSS platforms we have incorporated the small movable counterweight as part of the suspended scaffolding/working platform's rigid, steel frame. What then is different here, than in all other access types used in the world for under bridge access? It is a unique, patented solution, providing a safer, innovative way to access the underside of bridges, viaducts or other similar structures. the flexibility of SSS allows a design that will fit all existing suspended structures.it is adaptable to any size and location.the design of SSS allows for the easy negotiation of structural obstacles during relocation of the access platform.it is movable along structures of all geometry and shapes: straight, curved 2D and 3D.The counterweight retraction makes the scaffold free hanging so it can be moved along a track it provides safe and easy movement of SSS to multiple positions.it ensures minimal / no traffic interruption: SSS operation requires only a small area of deck to accommodate the track or mounting points which are placed very close to the edge of the structure.it does not require access to the ground beneath the bridge or structure: prepared and mounted entirely from the deck.provides improved safety through the counterweight displacement off the main structure which provides positive locking of scaffold/ working platform/ formwork during the working stage.it goes away with the need for traditional scaffold and the safety issues associated with traditional scaffold installation. the main advantage of SSS is the improved safety these platforms bring to ‘at height working’ as well as being cost effective, easy and simple.
