What is one common method of securing cargo in an open bed?

Using chains and binders is a reliable method for securing cargo in an open bed. This approach offers strong restraint for heavy loads, preventing them from shifting or falling during transport. Chains provide excellent tensile strength and can withstand significant forces without breaking, making them suitable for securing bulky or heavy items. Binders allow for easy tightening of the chains, ensuring that the cargo remains stable throughout the journey.

The other methods listed may not provide the same level of security or effectiveness. For instance, relying on a single large tarp may protect cargo from weather but does not adequately secure it against movement or shifting. Wheel chocks are primarily used to prevent the rolling of wheels and are not suitable for securing cargo in an open bed. Additionally, using a single strap for all cargo might not distribute the securing force evenly, leading to potential instability and risk of cargo movement.
