What is ringlock and cuplock scaffolding

 Ringlock Scaffolding

Ringlock Scaffolding System

As a modular scaffolding system, ringlock scaffolding is extremely
versatile, highly economical, more convenient and faster to use.

Ringlock Scaffolding Parts

Ringlock scaffolding parts are the connection that transmits forces
throughout the scaffold structure.

Cuplock Scaffolding

Cuplock Scaffolding System, is a scaffold system that uses the "Cup" and "Blade" to lock the vertical/standard and horizontal/ledger together, and lock the blades by twisting the cup. This Cuplock Scaffold System uses no nut, bolt or wedge. Cuplock’s Scaffolding System node-point is revolutionary, and makes it faster and easier than any other scaffolding system.

Ringlock Scaffolding System Application

Ringlock Scaffolding System for Construction

Ringlock scaffolding system is widely used in general tunnel and other bridge projects, viaducts engineering, plant buildings, elevated water towers, power plants, oil refineries, etc. as well as support design of special workshops, also suitable for overpasses, spans shacks, storage shelves, chimneys, water towers and interior and exterior decoration , Large-scale concert stage, background stand, grandstand, grandstand, modeling stand, staircase system, stage erection of evening party, grandstand of sports games, etc.

Ringlock Scaffolding System for Building

Fewer structures, convenient construction and disassembly, basic structure and special components, which can make the ringlock scaffolding system suitable for various structural buildings; it is composed of three types of members: Standards, Ledgers and Diagonals. These members are all made in the factory. First, this scaffolding design minimizes the problem of easy loss and damage of traditional scaffolding moving parts, and reduces the economic loss of the construction unit. Second, it does not have any movable ringlocking scaffold components, which prevents the traditional hidden danger caused by movable locking parts of scaffolding.
Better comprehensive benefits. Component series are standardized for easy transportation and management. No scattered and easily lost components, low loss, and low investment.

Features of Ringlock Scaffolding Design

 Ringlock scaffolding is self-locking mechanism with independent wedge insertion. Due to interlocking and gravity, the scaffolding ledger cannot be pulled out even if the wedge is not tightened.

 The ledger has a self-locking function, which can be locked or removed by pressing the wedge, and the contact surface between the rosette and the cast end is large, thereby improving the bending strength of the steel pipe, and ensuring that the standard does not skew.

 The vertical cross axis between Ringlock scaffolding standard and ledger is high in accuracy, and the stress property is reasonable. Therefore, the bearing capacity and overall rigidity are large, and the structure stability is strong. Each Standards can carry 3-4 tons.

 The number of Diagonals is much less than traditional scaffolding.
China scaffolding supplier EK comply with European, USA, Australian and others standards. Lab test will be done by third-party company (SGS, TUV…) as customers’ requirements.
