Advantages (Pros)

1. No External Power Required

• Operates by gravity or manual pushing
• Zero electricity consumption
• Energy-saving and environmentally friendly

2. Hygienic Stainless Steel Construction

• SUS304 frame provides excellent corrosion resistance
• Suitable for food, beverage, pharmaceutical and cleanroom applications
• Easy to clean and maintain

3. Low Maintenance

• No motor, gearbox, chain or belt required
• Minimal maintenance cost
• Simple wheel replacement when necessary

4. Cost Effective

• Lower investment than powered roller conveyors
• Simple installation and reduced operating costs

5. Improve Material Handling Efficiency

• Reduces manual lifting and carrying
• Faster loading and unloading process
• Smooth product transfer between workstations

6. Flexible Installation

• Can be installed with a slight slope for gravity flow
• Easy to integrate with existing conveyor systems
• Suitable for temporary or permanent production lines

Disadvantages (Cons)

1. Limited Load Capacity

• Not suitable for heavy pallets or high-load products
• Wheel loading capacity must be considered during design

2. Requires Flat Product Bottom

• Best suited for cartons, totes and trays
• Bags, drums or irregular-shaped products may not roll smoothly

3. No Speed Control

• Product speed depends on gravity and product weight
• May require stoppers or brakes to prevent product collision

4. Cannot Convey Uphill

• Suitable only for horizontal or declined conveying
• Powered conveyor is required for incline applications

5. Limited Automation Capability

• Additional sensors and stoppers are required for automatic systems
• Not ideal for high-speed automated production lines

6. Wheel Wear Over Time

• PU or plastic wheels will gradually wear
• Periodic inspection and replacement are required
