#SWING STAGE SCAFFOLD DEFINITION PROFESSIONAL#

The platforms must be designed in such a way that the failure of one means of support will not trigger the collapse or fail of any part of the platform even in the most adverse loading conditions including that the load factors, live and dead factors, and the safety factors will not be affected. At minimum, the design must meet the criteria as set out in the regulations. The design requirements for multi-point suspended work platforms are complex.

#SWING STAGE SCAFFOLD DEFINITION PROFESSIONAL#

Multi-point suspended work platforms – means a suspended work platform more than 750 millimetres in width or a system of suspended work platforms in which any one platform is more than 750 millimetres in width that is supported from an overhead fixed support system by at least three primary load-carrying means of suspension to maintain the stability of the work platform or system of work platforms.Ī multi-point suspended scaffold must be designed by a professional engineer.

A boatswain’s chair must be at least 600 millimetres long and 250 millimetres wide and must be supported by wire rope of at least nine millimetres if the worker is using corrosive substances, flame-cutting or mechanical-grinding equipment.

Stacked or tiered suspended scaffolds must have at least two independent means of support that would not fail at the same time.

Specially designed and manufactured counterweights with affixed legible instruction for use should be securely attached to the outrigger beams.

The distance between the outrigger scaffold and the wall behind is not greater than 75 millimetres.

The lines must each be capable of supporting the weight of the suspended load and of the supporting system.

The outrigger beam must be secured against vertical and horizontal movement and must be tied back to the fixed support by a secondary line.

The overhead fixed support or outrigger beams must be capable to support at least four times the maximum load to which it may be subjected.

Structural requirements for single and two-point suspended scaffolds include:

Single point suspended adjustable scaffold/boatswain chair – A platform suspended only by one rope from an overhead support and equipped with means to permit the platform to move vertically.

Two-point suspended scaffold (swing stage) – One or more work platforms suspended by two ropes from an overhead fixed support and equipped with equipment that permits the up and down movement.

, and scaffold-specific requirements prescribed by the regulations. There are several types of suspended scaffolds, but all of them have the same main components:Ī suspended scaffold or suspended platform must be designed based on good engineering practices,

This topic discusses suspended scaffolds. Scaffolds can be grouped in two main types: supported and suspended.

Suspended scaffolds consist of one or more platforms suspended from a permanent or temporary structure overhead structure by non-rigid components, such as ropes and wire cables. Scaffolds are temporary structures that consist of one or more elevated platforms used where work cannot be done on or from the ground, from a building or other permanent structure without hazard to the workers.
