• Adjustable height: Support legs can be adjusted to 450-680/550-820/750-1200/900-1500mm heights, accommodating various workstation designs

Setting Up Proper Slopes for Controlled Flow

The key to effective hospital supply chain management using gravity conveyors is establishing the correct slope for your specific products:

• Standard slope range: For most medical supplies, a 2-4° slope provides ideal movement
• Lightweight items: Boxes under 1kg may require slopes of 3-5° to ensure consistent movement
• Heavier products: Medical equipment over 10kg often requires only 1.5-3° to prevent excessive speed

When implementing a gravity system for medical supplies, consider:

1. Product testing: Test actual product samples to determine optimal slope angles
2. Speed control: Add inline braking sections for products that gain excessive speed
3. Transition points: Ensure smooth transitions between conveyor sections by maintaining precise height alignment
4. Flow control: Implement simple stop gates at key points to regulate product flow

Implementation tips for healthcare settings:

• Begin with a slightly lower angle than you think necessary and adjust upward
• Create modular sections that can be individually adjusted as needed
• Document optimal slopes for different product categories
• Ensure adequate runway at the end of decline sections

Maintaining Cleanliness

The maintenance of hygiene standards is particularly critical in pharmacy warehouse conveyor systems where medical products must remain uncontaminated throughout the handling process.

Easy-Clean Roller Surfaces

Naili’s gravity roller conveyors feature design elements that facilitate thorough cleaning:

• Surface materials: Zinc-plated or stainless steel rollers resist corrosion and can withstand regular sanitization
• Exposed roller design: Unlike belt conveyors, roller systems expose most surfaces for easier cleaning access
• Gap spacing: Sufficient spacing between rollers prevents debris accumulation
• Sealed bearings: Protected roller bearings prevent contamination of internal components

Recommended cleaning protocols for medical applications:

• Regular schedule: Establish fixed cleaning intervals based on usage volume
• Approved cleaners: Use only sanitizing agents approved for medical environments
• Documentation: Maintain cleaning logs to ensure regulatory compliance
• Training: Ensure staff understand proper cleaning procedures specific to roller conveyors

For maximum cleanliness in critical applications, consider:

• Selecting 201 stainless steel roller options for superior corrosion resistance
• Implementing removable sections that can be thoroughly cleaned off-line
• Creating standard operating procedures specific to each product type
• Scheduling preventive maintenance that includes comprehensive cleaning

Dust-Free Operation

Beyond regular cleaning, gravity roller conveyors offer inherent advantages for maintaining dust-free operations in medical environments:

• Movement mechanics: The rolling action naturally generates less dust than sliding friction systems
• Open design: Air can flow freely through the conveyor, preventing dust accumulation
• Visibility advantages: The open roller design makes dust or contamination immediately visible
• Accessible surfaces: All surfaces are easily reached for dust removal

To further enhance dust-free operation:

• Position gravity conveyors away from high-dust activities
• Consider dust covers for sections not in active use
• Implement regular compressed air cleaning to remove dust from roller bearings
• Create “clean zones” with positive air pressure for most sensitive products

For facilities handling particularly sensitive medical supplies, additional measures include:

• Dedicated clean-room conveyor sections with specialized materials
