Using dunnage air bags
→ Step 1: Load tightly against bulk head. Load each successive row tightly against previous row.
→ Step 2: Last units placed against side of trailer. Void should not exceed 18 inches. Fill excess void with other appropriate filler material.
→ Step 3: Always use proper material to protect bags from load face. No sharp edges or points may touch bag. Irregular load surfaces may require rigid buffering material.
→ Step 4: Attach “Quick Fill” tip by pressing down over the valve. Hold air bag in place until pressure builds up. A single airbag will stabilize the load. Inflate bag until the load is pressed against the sides.
→ Step 5: Check air pressure once air bag is in place and inflated.
→ Step 6: Deflate bag by unscrewing cap.
|Proper PSI for Air Bags|
|Level 1||3 PSI|
|Level 2||4 PSI|
|Level 3||6 PSI|
|Level 4||8 PSI|
|Level 5||10 PSI|
Dunnage Air Bags must operate at certain pressures in order to maintain maximum efficiency. When shipping by rail, ride quality is unpredictable and uncontrollable. Secure loads and perfect pressure for maximum operation are ideal for all businesses looking to withstand harsh shipping conditions. Whether is be lateral or longitudinal rail car bracing, or just regular blocking and bracing in truckload shipments, proper PSI is a crucial element to the usage of dunnage air bags.
