⚠️ SAFETY & OPERATIONAL GUIDELINES
1. Operational Safety
- Two-Person Rule: Manual opening and closing must be managed by two people to ensure fluid and synchronized movement.
- Pinch Point Awareness: Keep hands clear of the scissor pantograph system (crossbars) during operation to avoid entrapment.
- Clearance: Ensure the wheel path is free from debris or obstacles before moving the tunnel.
2. Environmental & Wind Safety
-
Wind Resistance: Safety is certified only when using anti-lift guides or lateral tie rods.
- Standard Config: Wind speed rating is significantly reduced without stability kits.
- Reinforced Config: Stability is ensured up to 62 mph (100 km/h) with lateral tie rods.
- Snow Load: Clear snow accumulation or remove the PVC cover during heavy storms to prevent structural failure on unheated structures.
3. Installation & Maintenance
- Anchoring: Always secure the structure using provided safety straps, steel cables, or ballasts.
- Fire Safety: Use only original fireproof PVC. Ensure no flammable materials are stored directly against the fabric.
- Regular Inspection: Periodically check pantograph locking mechanisms and wheel integrity.
