Types of modular scaffolds – Ringlock, Cuplock and Kwikstage scaffolding explained
Unlike traditional tube and coupler scaffolding, modular or system scaffolding consists of prefabricated modular components that are assembled at fixed connection points. This makes them suitable not only for construction and renovation projects, but also for industrial applications such as refineries, chemical plants, shipyards, mining or offshore installations.
The most commonly used modular scaffolding systems include Ringlock scaffolding, Cuplock scaffolding and Kwikstage scaffolding. What they all have in common are the standardised scaffold bays and pre-defined connection points, which speed up the scaffold assembly and dismantling and simplify general handling. Find a brief overview of the main differences and features of each scaffolding type here.
1. Ringlock modular scaffolds
Ringlock modular scaffolding, also known as rosette scaffolding, is a scaffolding type that consists of verticial standards with ring-like node points at regular intervals, allowing for easy assembly and disassembly. Each connector has 8 punched holes into which ledgers and transoms can be hooked into and then be secured in place with a hammer.
With a manageable number of components, this type of modular scaffolding is quick to assemble, easy to transport and easy to store. Ringlock scaffolds can be adapted to a variety of shapes, making them the ideal fit for both industrial and construction applications. This makes them a popular choice among scaffolders, especially in Europe and Northamerica.
2. Cuplock modular scaffolds
Cuplock modular scaffolding is a scaffolding system used mainly in Asia. The name ‘Cuplock’ derives from the cups used to connect the ledgers and transoms with each other.
Each node point consists of a lower fixed cup and an upper movable cup, which can hold a total of 4 ledgers and transoms. The T-shaped hooks of the ledgers or transoms are first hooked into the lower cup, then the upper movable cup is pushed onto the upper hook of the ledger or transom and initially tightened by hand. Finally, the joint is fixed with 3-4 well targeted hammer blows.
3. Kwikstage modular scaffolds
Kwikstage modular scaffolding, sometimes also called Quick Stage scaffolding, is ideal for light and medium duty projects. This type of modular scaffolding is characterised by its prefabricated triangular pressings on the scaffolding standards. Up to four ledgers can be attached to these at the same time.
Kwikstage scaffolding is particularly popular in Australia and New Zealand, where it accounts for 80 per cent of total market usage.
Modular scaffolds including Ringlock, Cuplock and Kwikstage share common benefits such as versatility, quick assembly, stability, and high load-bearing capacities.
