The legal requirements for using truck and trailer anchors for tie-downs are primarily governed by the Federal Motor Carrier Safety Administration (FMCSA) in the United States. Key requirements include:
1. **Working Load Limit (WLL):** The aggregate WLL of all tie-downs must be at least 50% of the weight of the cargo. Each tie-down must be marked with its WLL.
2. **Number of Tie-Downs:** At least two tie-downs are required for cargo that is 5 feet or shorter and weighs 1,100 pounds or more. Cargo over 5 feet but less than 10 feet requires at least two tie-downs, regardless of weight. Cargo over 10 feet requires additional tie-downs.
3. **Anchor Points:** Anchor points must be strong enough to withstand the forces applied by the tie-downs. They should be inspected regularly for wear and damage.
4. **Tie-Down Types:** Acceptable tie-downs include chains, synthetic webbing, wire rope, and steel strapping. They must be in good condition, without cuts, frays, or damage.
5. **Securement Methods:** Cargo must be secured to prevent movement in any direction. This includes forward, backward, sideways, and vertical movement.
6. **Inspection:** Drivers must inspect cargo and tie-downs before the trip, within the first 50 miles, and every 150 miles or three hours thereafter.
7. **Specialized Requirements:** Certain types of cargo, such as logs, vehicles, and heavy machinery, have additional specific securement requirements.
8. **State Regulations:** Some states may have additional regulations, so it is important to check local laws.
Compliance with these regulations is crucial for safety and to avoid penalties. Non-compliance can result in fines, out-of-service orders, and increased liability in the event of an accident.
