Hence, load capacity of such components must be checked for suitability to support resultant loads. WLL s for couplers shown may be limited by components to which they are attached. Working Load Limits Working Load Limits (WLL s) are given for couplers that are covered by AS and comply to that standard. This manual includes basic types of scaffold couplers which join two tubes together as well as special couplers used to connect scaffold tube to other components, equipment or structures. This basic fi tting that is designed to join two scaffold tubes can be used to create a diverse range of scaffolding structures or used as an accessory to prefabricated scaffolding systems. Tube-and-coupler scaffolding is defi ned in AS as 'a scaffold in which individual circular tubes serving as standards, ledgers, braces or ties are joined together by means of purpose designed couplers'. Outstanding Service.Ģ Introduction Scaffold couplers are essentially the fundamental component that is used to assemble tube-and-coupler scaffolding as encompassed by AS1576. 1 SCAFFOLDING PRODUCT TECHNICAL GUIDE Scaffold Couplers Genuine Safety.
