What is the minimum angle an indirect tiedown must make with the deck to prevent side-to-side cargo movement?

To effectively prevent side-to-side cargo movement using an indirect tiedown, it is essential that the tiedown maintains a minimum angle with the deck. An angle of 30 degrees is widely recognized in safety and cargo securing guidelines as the threshold necessary for achieving adequate tension and stability. This ensures that the forces exerted on the cargo are sufficient to resist lateral movements during transport.

At angles less than 30 degrees, the tiedown may not provide enough leverage to securely hold the cargo in place against lateral forces, such as those experienced during sudden stops or turns. Thus, utilizing an angle of 30 degrees or greater enhances the effectiveness of the tiedown system, making it crucial for maintaining cargo integrity and overall safety during transit.
