Abstract: A method of stabilizing a suspended scaffolding system against a main stable structure by using the intentional displacement of the centre of gravity of the suspended scaffold off its equilibrium position and preventing the return of the centre of gravity to the equilibrium free-hanging state. The displacement of the centre of gravity is to be achieved by movement of the counterweight of the suspended scaffolding. The centre of gravity is prevented from returning to the equilibrium position by using adjustable bumpers between the suspended scaffolding system and the main stable structure. A restoring gravity force induced by the displacement of the centre of gravity off the equilibrium position acts as a pushing force to provide firm stabilization of the suspended scaffolding against the main stable structure.
