Preventing bicycle inner tubes from being damaged during transportation requires strict control over four aspects: packaging, protection, loading and unloading, and the transportation environment. Here are specific measures:
Standardized Packaging: Inner tubes should first be individually packaged in cardboard boxes or material bags, then grouped together in sturdy cardboard boxes as outer packaging. Each box can hold 50 or 100 tubes, ensuring the packaging is secure and not loose. The outer packaging must clearly indicate the manufacturer's name, specifications, quantity, weight, production date, etc., for easy traceability and management.
Avoiding Physical Damage: During transportation, inner tubes must not be mixed with sharp objects to prevent punctures or scratches. Use wide fiber slings or dedicated forklift covers when handling. Never use steel wire ropes or ropes, or directly insert a forklift into the inner tube for handling, to avoid damaging the bead or valve stem.
Controlling the Transportation Environment: Inner tubes should be covered with tarpaulins during transportation to prevent exposure to sun and rain. Avoid prolonged exposure to high temperatures, high humidity, or strong ultraviolet radiation to prevent rubber aging, deformation, or performance degradation. In summer, ensure proper ventilation and heat dissipation; in humid environments, take precautions against moisture.
Do not mix with hazardous materials: Do not transport with oils, flammable materials, or corrosive chemicals to prevent swelling, cracking, or chemical reactions that could damage the rubber.
Proper stacking and securing: Stack the inner tubes stably inside the vehicle, off the ground and away from walls, to avoid deformation under pressure. When stacking multiple layers, use partitions to distribute pressure and prevent the lower inner tubes from being crushed. Regularly check the securing during transport to prevent displacement or collisions due to bumps.
