## 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.

## Claims

### Claim 1

A method for stabilizing a suspended scaffolding system against a structure, the method comprising:
coupling an attachment system to a surface of the structure;
mounting a suspended working platform having a counterweight to the attachment system such that the counterweight is movable between a first position and a second position;
moving the counterweight from the first position in which a center of gravity of the scaffolding system is positioned in a vertical plane of the attachment system and the scaffolding system is in an equilibrium state to the second position in which the center of gravity of the scaffolding system is displaced away from the vertical plane of the attachment system and the scaffolding system is in a nonequilibrium state; and
securing the counterweight in the second position while preventing a return of the suspended working platform center of gravity to the first position in the vertical plane of the attachment system by using an adjustable bumper between the suspended working platform and the structure; and
stabilizing the suspended working platform against the structure by maintaining the center of gravity being not in the vertical plane of the attachment system and utilizing a restoring gravity force to push the suspended working platform towards the structure.

### Claim 2 (depends on 1)

The scaffolding system of claim 1, wherein the counterweight is movable from the first position to the second position by at least one of a manual displacement method and a mechanical displacement method.

### Claim 3 (depends on 2)

The scaffolding system of claim 2, wherein the mechanical displacement method is operated via a remote control.
