Aluminium Mobile Scaffold Spacing Settings

When working with aluminium mobile scaffold, understanding the proper spacing settings is crucial for safety, stability, and compliance with industry standards. Setting the correct spacing not only ensures a secure work platform but also improves efficiency on job sites. In this guide, we’ll break down the different aspects of spacing configurations for aluminium mobile scaffolds, covering various scenarios, best practices, and regulatory compliance.

Let’s dive into the details of spacing settings you need to consider when working with aluminium mobile scaffolds.

1. Platform Height and Vertical Spacing

Adjusting Platform Heights

The platform height for aluminium mobile scaffolds should be set according to the nature of the work and safety standards.

Key Guidelines:

For most tasks, platforms should be positioned no higher than 2 meters without additional fall protection.

Beyond 2 meters, handrails and mid-rails are required.

Platforms should be set at intervals that allow workers to comfortably access materials and tools.

Vertical Spacing Between Platforms

When multiple platforms are needed, the vertical spacing between them should generally be set between 1. 5 meters to 2 meters.

Process:

Measure the Distance: Ensure even spacing for stability.

Add Guardrails: For platforms above 2 meters, install guardrails at each level.

Secure Access Points: Include secure ladders or stairways between levels for safe access.

2. Horizontal Brace Spacing

Setting Up Horizontal Braces

Horizontal braces play a crucial role in maintaining the scaffold’s stability and rigidity. The spacing between horizontal braces should comply with safety guidelines to prevent any lateral movement.

Standard Spacing:

1. 5 meters to 2 meters is the recommended spacing for horizontal braces.

Process:

Align Braces: Install horizontal braces at regular intervals along the scaffold height.

Check Stability: Ensure each section is firmly secured to avoid swaying.

Tighten Connections: Make sure all joints and connections are tight to maintain the scaffold’s integrity.

3. Diagonal Brace Configuration

Importance of Diagonal Braces

Diagonal braces provide essential cross-support for aluminium mobile scaffolds. Correct spacing and placement of these braces prevent the scaffold from tilting or collapsing.

Recommended Spacing:

Diagonal braces should be installed every 1. 5 meters vertically for optimal support.

Process:

Install Diagonals: Place diagonal braces from the bottom to the top of the scaffold.

Cross Patterns: Use a cross-bracing pattern to distribute weight evenly.

Securely Fasten: Ensure all braces are securely fastened to avoid shifting during use.

4. Caster Wheel Spacing

Configuring Caster Wheel Placement

The spacing and alignment of caster wheels impact the mobility and stability of aluminium mobile scaffolds.

Standard Configuration:

Caster wheels should be positioned at each corner of the scaffold frame.

The spacing should align with the scaffold’s base width to maintain balance.

Process:

Equal Distance: Ensure each wheel is equidistant from the scaffold’s centre.

Locking Mechanism: Engage the locking mechanism before use.

Base Extension: For higher scaffolds, use base extensions to widen the spacing for added stability.

5. Guardrail Spacing

Setting Guardrail Heights and Gaps

Guardrails are mandatory for scaffolds above 2 meters. Correct spacing of guardrails ensures worker safety.

Key Spacing Guidelines:

Top Rails: Positioned at 900 mm to 1100 mm above the platform.

Mid Rails: Positioned halfway between the platform and the top rail.

Toe Boards: Must be installed at the platform level to prevent tools from falling.

Process:

Install Top Rails: Measure and attach the top rail at the correct height.

Add Mid Rails: Install mid rails to maintain the required spacing.

Check Stability: Ensure all rails are securely fastened.

6. Access Ladder Spacing

Positioning Access Ladders or Stairs

Access ladders or stairs must be spaced correctly to ensure safe and easy movement between scaffold levels.

Guidelines:

Ladders should be positioned at an angle of 75 degrees.

The maximum spacing between ladder rungs should be 300 mm.

Process:

Install Ladders: Attach ladders to the scaffold frame at the appropriate angle.

Secure Rungs: Ensure rungs are evenly spaced and secure.

Check Access Points: Verify that ladders provide safe access to each platform level.

7. Deck Spacing

Configuring Decks and Planks

The spacing of decks and planks affects the usability and safety of the scaffold platform.

Guidelines:

Decks should be placed tightly together to avoid gaps.

Any gaps should not exceed 25 mm to prevent tripping hazards.

Process:

Lay Decks: Position decks side-by-side with minimal gaps.

Secure Planks: Fasten planks securely to prevent movement.

Check for Stability: Walk across the platform to ensure it is firm and stable.

8. Spacing for Load Distribution

Balancing Loads on the Scaffold

Proper spacing helps distribute the load evenly across the scaffold.

Guidelines:

Distribute weight evenly to avoid overloading any section.

Do not exceed the load capacity specified by the manufacturer.

Process:

Plan Placement: Spread materials and workers evenly across the platform.

Avoid Concentration: Do not place heavy loads in one spot.

Check Regularly: Inspect the scaffold for signs of strain or imbalance.

9. Spacing for Outdoor Use

Adjustments for Wind and Weather Conditions

When using aluminium mobile scaffolds outdoors, spacing adjustments may be necessary to ensure safety.

Key Considerations:

Use wider base spacing to counteract wind forces.

Secure scaffolds with outriggers for added stability.

Process:

Widen Base: Extend the base width to enhance stability.

Install Outriggers: Attach outriggers to prevent tipping.

Monitor Weather: Avoid using scaffolds during high winds.

10. Compliance With Australian Standards

Adhering to AS/NZS 1576 Guidelines

Ensure your spacing settings meet Australian safety standards (AS/NZS 1576) for aluminium mobile scaffolds.

Key Requirements:

Platforms above 2 meters require guardrails and mid-rails.

Braces and platforms must be evenly spaced for stability.

Process:

Review Standards: Familiarize yourself with AS/NZS 1576 guidelines.

Inspect Regularly: Perform regular checks to ensure compliance.

Train Workers: Ensure all users are trained in proper spacing configurations.

Conclusion

Correct spacing settings for aluminium mobile scaffold are essential for maintaining safety, stability, and compliance. By following these detailed guidelines of GW Equip for platform height, brace configuration, caster wheel placement, and guardrail spacing, you can ensure your scaffold setups are secure and efficient. Whether working indoors or outdoors, attention to spacing details will help you avoid potential hazards and meet industry standards.
