Materials And Tools Needed:

• Base plates or adjustable base jacks
• Vertical standards (uprights)
• Horizontal ledgers
• Diagonal braces
• Ringlock rosettes (integral to standards)
• Planks or platforms
• Ladders (internal or external, if required for climbing)
• Guardrails and toeboards
• Safety harness and fall protection gear
• Wrenches and scaffold-specific tools (if needed)

Building A Ringlock Scaffold Tower:

Site Preparation

• Check the ground: Ensure the ground or surface where the scaffold will be erected is stable, level, and solid. If the ground is uneven, use base jacks for leveling.
• Safety clearance: Clear the area of debris, obstacles, or any hazardous materials.
• Permits and inspection: Make sure the construction follows local regulations, and obtain necessary permits.

Set Up Base Plates Or Adjustable Base Jacks

• The post head jacks should be installed on the ground, one from the other according to the drawings, which shall not exceed a distance of 30cm between deck and building. The scaffolding will be erected on load-distribution plates or structures capable of withstanding all imposed loads.
• Base standards shall be put on the post head jacks with the nipple side upwards; these standards permit good alignment and leveling of the base; and allow, furthermore, a reduction of the first ring to ground level by 200mm. 

Install Vertical Standards (Uprights)

• Form a base frame by connecting the base standards transversely with the decking transom (0.75mor 1.05m) and longitudinally with the ledgers. Insert the wedge in the corresponding holes in the lower rings of the standard. Ensure all ledgers and decking transoms are leveled by adjusting the post head jacks. Then securely fix all the wedges.
• Place the first platforms as an assembly aid to check squareness, they can be removed later. This does not apply to bays where access platforms are fitted, in these bays two platform units should be fitted to support the ladder. When placing the platforms on the transoms they are self-locked, in order to remove them you have to open the lock by moving the hook upwards. More over no gap fillers are required between platforms.

Attach Horizontal Ledgers

• Insert the first level vertical standards into the base standards. lt's recommended to start the assembly with standards of 2.5m inorder to provide safe position for the scaffolders when they cometo the next level. 
• At 2m from the horizontal ledgers already installed, put up thenext horizontal ledgers and decking transoms, secure thewedges. Fit the next platform units from below. For the accesspays access platforms are used. Alternate the direction oftheladders for each level! When the ladder access is not being usedthe access hatch must remain closed.

Install Diagonal Braces

• Attach diagonal braces: These braces are essential for the stability of the tower. Attach the diagonal braces to the rosettes, connecting the vertical standards diagonally across the scaffold. This helps prevent swaying and increases the tower’s structural strength.
• Check for plumb: After installing the braces, use a spirit level to ensure that the scaffold is plumb and square.

Repeat for Higher Levels

• Add vertical standards: Continue adding vertical standards to the first level using the built-in coupling pins or connectors.
• Attach ledgers and braces: At each new height, install horizontal ledgers and diagonal braces, repeating the process for each level until the desired height is reached. Always check the alignment and stability as you go.
• Platform placement: Every few levels, install planks or platforms for workers to stand on. Ensure the platforms are securely fastened and level.

Install Guardrails and Toeboards

• Safety first: As you reach the top of the scaffold, install guardrails and toeboards on the working platforms to prevent workers from falling.
• Guardrails: Attach these to the vertical standards at waist height (about 1 meter or 3 feet above the platform).
• Toeboards: Install toeboards around the edges of platforms to prevent tools or materials from falling.

Secure Ladder Access

• Internal or external ladders: Depending on the scaffold design, install ladders to provide access to different levels of the scaffold. Use safe and secure ladder brackets to hold the ladders in place.
• Secure ladders: Make sure the ladders are securely fastened to avoid shifting or instability during use.

Final Inspection

• Check connections: Ensure all ledgers, standards, and braces are properly locked and secure. Double-check wedge locks and other connection points.
• Stability test: Slightly shake or push the scaffold to ensure it’s stable and doesn’t wobble.
• Level check: Use a level to verify the scaffold remains plumb and even.
• Safety check: Inspect all platforms, guardrails, toeboards, and ladders to ensure they meet safety standards.
