What Components Make Up Ringlock Scaffolding?

The core of the ringlock scaffolding structure lies in its individual components. Without these parts, the scaffolding system cannot be assembled or take shape. Although a wide variety of parts are involved, a few key components are absolutely essential; they ensure that the entire structure stands firmly and securely upright on the ground.
Rosettes: These serve as the connection points linking the standards (vertical posts) to the ledgers (horizontal beams), designed to enhance the structural stability.
Ledgers: Ledgers are horizontal support beams that provide the load-bearing surfaces necessary for the assembly and construction of the scaffolding.
Standards: Standards are the fundamental structural elements of the scaffolding system. These vertical posts provide the scaffolding with its required height and structural strength.
Diagonal Braces: These angled support members are used to prevent the structure from swaying, thereby ensuring overall stability.
Base Collars: Base collars act as anchoring points, ensuring that the scaffolding stands firmly upright and remains securely fixed to the ground.

Base Jack: Base jacks serve an anchoring function, ensuring that the scaffolding remains stable and upright, and is firmly secured to the ground.
Steel Planks: These constitute the platform surface upon which workers walk. They serve as the passageways for personnel to move and work within the scaffolding, providing a solid and reliable foothold.
Guardrails: Protective barriers positioned along the edges of the structure, designed to prevent personnel from falling off the sides and to ensure operational safety.
Toe Boards: Low-profile barrier components located at the base, designed to prevent tools and materials from falling off the scaffolding.

Rosette

The rosette connection serves as the structural core of the ringlock scaffolding system. Each rosette features four large apertures and four small apertures, enabling components—such as ledgers, diagonal braces, beams, and triangular brackets—to connect simultaneously with the vertical standards from eight distinct directions. Thanks to its unique eight-hole geometric configuration, this connection point facilitates full 360-degree connectivity. Our ringlock rosette are manufactured from 10mm-thick Q355B steel and are seamlessly integrated with the vertical standards using a circumferential seam welding process executed by Golden Lion's automated welding machinery. This process ensures that the connection points possess high strength and semi-rigid characteristics, thereby fully meeting the load-bearing requirements stipulated by the EN 12810 standard for industrial and offshore scaffolding projects.

Ringlock Standard

In a modular scaffolding structure, the ringlock scaffolding standard serves as the vertical component. It is manufactured from steel scaffolding tube with outer diameters of 48.3 mm and 60 mm, respectively. The height of the standards in this disc system typically ranges from 0.5 meters to 4 meters. Discs are welded onto the standard at intervals of 500 mm to facilitate the connection of other components within the ringlock system—such as ledgers, diagonal braces, and triangular brackets.

Ledger End

The ledger ends manufactured by EK Scaffolding are cast from ZG230-450 grade steel, achieving a minimum joint shear strength of up to 25 kN. Precision-machined using CNC technology, these ledger ends feature exact dimensions that ensure a precise fit with the rosette standards, thereby effectively minimizing structural sway. Welded using Golden Lion automated welding machines, they achieve full-penetration welds characterized by robust seams and uniform strength, completely eliminating the risks associated with missed or weak welds. This ensures that the scaffolding platform remains rigid and stable at all times, even in high-altitude working environments exceeding 50 meters.

Ringlock scaffolding is self-locking mechanism with independent wedge insertion. Due to interlocking and gravity, the 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 standard and ringlock scaffolding 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 Standard can carry 3-4 tons. The number of Braces is much less than traditional scaffolding.

Comply with European, USA, Australian and others standards. Lab test will be done by third-party company (SGS, TUV…) as customers’ requirements.

EK Scaffolding Recommendations:
1. Structural Mechanics Advantages
Ringlock: Features an octagonal rosette design that aligns the connection points between ledgers and standards along the central axis. This centralized load-bearing arrangement minimizes eccentric stress, resulting in superior torsional resistance and overall structural stability compared to Cuplock systems.
2. Operational Efficiency Comparison
Based on on-site field data, for scaffolding projects of comparable scale, Ringlock systems can be erected approximately 30% faster than Cuplock systems. The primary reason for this efficiency lies in the rosette-based design, which allows wedge pins to be secured simply by hammering; this effectively eliminates common issues found in cup-type systems—such as component jamming, dust accumulation, or corrosion—that can prevent cuplock nodes from rotating freely.
3. Market Application Recommendations
Ringlock Scaffolding: Best suited for complex structures requiring a high degree of flexibility and exceptional load-bearing capacity.
Cuplock Scaffolding: An economical and efficient solution for linear scaffolding structures, such as those used in facade work and formwork support systems.
Kwikstage Scaffolding: A versatile system ideally suited for general construction projects with moderate load-bearing requirements.

What Is The Installation Process For Ringlock Scaffolding?

Installation Process

1. Define the Construction Scope: Determine the scaffolding erection area based on the design drawings. Mark out the layout and positioning according to the specified dimensions, making adjustments as necessary during construction based on actual site conditions.
2. Install Adjustable Base Jacks: Ensure the ground surface is level and firm. Lay down base plates at the planned locations and place the adjustable base jacks upon them.
3. Install Base Collars: Fit the base collars (base sleeves) over the adjustable base jacks. Adjust the nuts on the base jacks to ensure that all base collars are aligned at the same horizontal elevation.
4. Erect Standards and Ledgers: Insert the vertical standards into the base collars. Connect the horizontal ledgers to the ringlock rosette located on the standards, and drive the wedge pins into the small holes on the rosettes to secure the connections.
5. Install Diagonal Braces: Diagonal braces should be installed in a grid-like pattern to enhance structural stability and ensure the scaffolding structure remains plumb and square.
6. Install scaffolding plank and Safety Guarding: Lay steel plank ( scaffolding walk board) across the horizontal ledgers. Install toe boards along the edges and erect guardrails to ensure operational safety.
7. Erect the Second Tier: Repeat steps 4 through 6 until the ringlock scaffolding system reaches the specified height.

Key Points for Ringlock Scaffolding Construction

1. The exposed length of the adjustment screw on the adjustable base jack must not exceed 300 mm.
2. The vertical standards are typically arranged in one of two configurations: a matrix-spiral pattern (resembling a lattice column structure), or a symmetrical "figure-eight" pattern (or symmetrical "V" pattern).
3. Once the scaffolding height reaches the design specifications—and prior to pouring concrete—the ringlock scaffolding system must undergo a formal acceptance inspection.
4. The ringlock scaffolding system must comply with design requirements, remaining level and stable; no components shall be loose or left unsupported (hanging).
5. The cantilevered extension length of adjustable U-head jacks and adjustable base jacks beyond the horizontal ledgers must strictly adhere to design specifications.
6. Verify that the wedge pins on the vertical diagonal braces are securely fastened and aligned parallel to the vertical standards; similarly, verify that the wedge pins on the horizontal ledgers are aligned perpendicular to the ledgers.
7. Verify that the installation positions, quantities, and layout configurations of all structural members comply with the design specifications.
8. All locking pins on the ringlock scaffolding must be in the locked position; cantilevered sections must be positioned precisely; horizontal ledgers and vertical diagonal braces must be fully installed at every tier (or lift); locking pins must be securely fastened; and all safety protection measures must be fully implemented.
9. Appropriate safety protection measures—such as horizontal safety nets—must strictly adhere to the requirements outlined in the specialized construction plan.
10. Records pertaining to installation activities and quality inspections must be maintained in a timely and comprehensive manner.

Key Safety Guidelines

Personal Protective Equipment (PPE): All personnel performing work must wear safety helmets, anti-slip gloves, and safety footwear.
Load-bearing Capacity and Stability: The "4-to-1" stability principle must be strictly observed; specifically, in the absence of additional bracing, the erected height of the scaffolding must not exceed four times the dimension of the shortest side of its base.
Material Inspection: The use of any structural components that are damaged, bent, deformed, or severely corroded is strictly prohibited.
Component Compatibility: If components from different manufacturers are to be combined, a separate verification of their compatibility must be conducted.
