When securing heavy vehicles, what is the minimum WLL of each tiedown?
What is the minimum WLL required of tiedowns securing loaded intermodal containers on non-chassis vehicles?
Secure each container to the vehicle by:
Secure the front and rear of the loaded container independently.
Secure the four corners using tiedowns that are attached to the loaded container.
The tiedowns must have an aggregate working load limit of at least 50% of the loaded weight of the loaded container.
Attach each chain, wire rope, or integral locking device to the container in a manner that prevents it from becoming unfastened while in transit.
How many anchor points should be used to secure an intermodal container on a chassis vehicle?
Secure the front and rear of the container independently.
Which of the following is not a reason why loads should be secured?
High friction securement devices include:
When securing paper rolls with eyes vertical in a sided vehicle all of the following are acceptable except:
Aggregate Working Load Limit is defined as:
The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
The North American Cargo Securement Standard cover vehicles weighing:
To secure paper rolls with eyes horizontal against rearward movement, you can use which of the following except:
Methods to Prevent Movement:
When securing a single metal coil with eyes vertical:
To prevent the coil from tipping forward, rearward, and sideways, arrange tiedowns to include the following:

Studying the flatbed cargo securement CDL manual is not a requirement for getting your CDL permit or license. It is required knowledge for flatbed drivers.
Some questions you should be able to answer for flatbed cargo securement:
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
A combination of securing devices that forms an assembly that:
Some tiedowns are attached to the cargo and provide direct resistance to restrain the cargo from movement.
Some tie-downs pass over or through the cargo. They create a downward force that increases the effect of friction between the cargo and the deck. This friction restrains the cargo.
A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Tiedowns can be used in two ways:
Place the tiedown as close as possible to the spacer.
Position the tiedowns as symetrically as possible over the length of the article.
Position the tiedowns to preserve the integrity of the article.
