Load Capacity Matters

A caster must support:

• The scaffold itself;

• Workers;

• Tools;

• Materials.

Professional scaffold casters typically provide load capacities up to:

• 500 kg

• 720 kg

Higher load capacity improves safety and reliability.

Avoid Iron Components

Construction environments often involve:

• Water

• Humidity

• Outdoor exposure

Iron parts are susceptible to corrosion.

Aluminum scaffold accessories with corrosion-resistant materials offer longer service life and reduced maintenance.

Single Brake vs Double Brake Casters

Single-Pedal Casters

Advantages:

• Lower cost

Disadvantages:

• Difficult to unlock

• Less convenient

• Lower load capacity

Double-Pedal Casters

Advantages:

✓ Easier operation

✓ Hands-free release

✓ Higher load capacity

✓ Improved efficiency

Double-pedal casters are commonly preferred for professional applications.

Adjustable Screw Jacks

The adjustable screw section allows users to:

• Level the scaffold;

• Compensate for uneven ground;

• Increase stability.

Proper leveling is critical for safe operation.

Mobility and Safety

Good scaffold casters should provide:

• Smooth rolling;

• Reliable brakes;

• High load capacity;

• Corrosion resistance;

• Easy adjustment.

These factors are often more important than price alone.

Conclusion

When choosing mobile aluminum scaffolding casters, pay attention to:

• Load capacity;

• Brake design;

• Corrosion resistance;

• Adjustable screw jacks;

• Ease of operation.

High-quality casters improve both safety and efficiency and are an essential part of professional scaffold systems.
