Go!When securing concrete pipe loaded crosswise, arrange the top tier:
Arrange the top tier as a complete tier, a partial tier in one group, or a partial tier in two groups.
To secure paper rolls with eyes horizontal against rearward movement, you can use which of the following except:
Methods to Prevent Movement:
What is the minimum amount of rearward force that a cargo securement system must withstand?
Each cargo securement system must be able to withstand a minimum amount of force in each direction.
Load securement for cargo weighing 29,650 lbs must be able to withstand upward force of how many lbs?
All elements of the vehicle structure and anchor points must be strong enough to withstand the forces described on page 7.
If loading and securing paper rolls on a second layer:
How many tiedowns are required on a stack of shortwood loaded crosswise?
Use two tiedowns to secure one stack of shortwood loaded crosswise.
Attach the tiedowns to the vehicle frame at the front and rear of the load.
Position tiedowns approximately 1/3 and 2/3 of the length of the logs.
What is the minimum WLL of each tiedown used to secure crushed or flattened vehicles?
Has containment walls on three sides that:
Secures each stack of vehicles with a minimum of two tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Has containment walls on two sides that:
Secures each stack of vehicles with a minimum of three tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Has a minimum of four tiedowns per vehicle stack with each tiedown having a minimum WLL of 2,268 kg (5,000 lb.).
High friction securement devices include:
When using tiedowns to secure boulders, all of the following are requirements except:
Use only chain to secure large boulders.
Should be located in valleys or notches across the top of the boulder
Must be arranged to prevent sliding across the rock surface.
When loading and securing a boulder, it should be:
Place each boulder on the vehicle with its flattest and/or largest side down.
Support each boulder on at least two pieces of hardwood blocking (at least 10 cm x 10 cm (4 x 4 in) that extend the full width of the boulder.
Place hardwood blocking pieces as symmetrically as possible under the boulder so they support at least 3/4 of the length of the boulder.
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.
