Go!Within the requirements for concrete pipe, which of these requires specific securement methods?
Follow general cargo securement requirements (Section 2) when transporting the following pipe:
Any concrete pipe loaded crosswise on a platform trailer or vehicle that is not exempt.
When securing concrete pipe up to 45 inches loaded crosswise, tiedowns through the pipe must be:
The term 'edge protector' refers to:
A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
A dunnage bag is:
An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
When securing concrete bell pipe in multiple complete tiers, all of the following are true except:
Bells of the bottom tier must all be on the same side of the vehicle
Bells of the upper tiers must be are on the opposite side of the vehicle from the bells of the tier below.
Specific securement methods are required for boulders that:
Weighs more than 5,000 kg (11,000 lb.) or has a volume greater than two cubic meters
Is transported on an open vehicle or in a vehicle whose sides are not designed and rated for the transportation of boulders.
To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?
The securement of a cubic-shaped boulder must meet these requirements in addition to the other large boulder requirements in Section 13.
Secure each boulder individually with at least two chain tiedowns placed side-to-side across the vehicle.
Place tiedowns as closely as possible to the hardwood blocking used to support the boulder.
When securing building materials, how many tiedowns are required for top tier bundles longer than 5 ft?
Tiedowns over the top tier of bundles with a minimum of 2 tiedowns over each top bundle longer than 1.52 m (5 ft).
What is the maximum angle recommended for tiedowns securing cement pipe loaded crosswise, relative to the deck?
Attach an additional tiedown that runs rearward at an angle not more than 45 to the horizontal when viewed from the side of the vehicle, whenever practical.
Pass tiedown either through the front pipe of the upper tier or outside the front pipe and over both longitudinal tiedowns.
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.
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.
