Key Considerations When Choosing an Expandable Roller Conveyor

When selecting the right flexible expandable roller conveyor for your operation, evaluate these critical factors:

1. Required Length Range: Determine both the minimum and maximum lengths needed for your application. Consider the 1:3 expansion ratio of most roller conveyors when planning.
2. Load Requirements: Assess the weight of your typical items and ensure the conveyor’s load capacity (50-100 kg/m depending on model) adequately supports your needs.
3. Powered vs. Gravity: For horizontal transport or precise speed control, powered models offer advantages. For simple inclined movement or budget concerns, gravity systems may suffice.
4. Roller Diameter: Larger diameter rollers (50mm) provide better support for heavier items, while smaller rollers (38mm) may offer more contact points for lighter goods.
5. Mobility Needs: Consider whether the conveyor will remain stationary or require frequent repositioning. All models include casters, but weight varies between types.

For operations requiring height differentials between floor level and vehicles, consider complementing your expandable conveyor with a Hydraulic Conveyor for a complete loading/unloading solution.

Installation and Maintenance

Expandable roller conveyors are designed for simplified setup and minimal maintenance:

Installation Basics

• Ensure a flat, stable floor surface
• Adjust leg heights to achieve desired slope (for gravity models) or horizontal alignment
• Lock casters once positioned
• For powered models, connect to appropriate power supply (typically 380V or 220V)
• When connecting multiple sections, ensure proper alignment at junction points

Maintenance Requirements

• Daily Check: Visual inspection of rollers and framework
• Weekly Maintenance: Verify free rotation of all rollers and clean surfaces
• Monthly Service: Check and tighten connections, lubricate bearings
• Quarterly Inspection: Examine drive belts (for powered models) and adjust tension as needed

With proper care, expandable conveyor frames typically last 5-10 years under normal usage conditions. Drive belts on powered models may require replacement every 6-12 months depending on usage intensity.
