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.
What is the minimum aggregate WLL of all tiedowns in a group of concrete pipe?
The aggregate working load limit of all tiedowns on any group of pipe must be more than half the total weight of all pipes in the group.
Which of the following are not covered by the specific log securement requirements?
The following types of logs are not covered by the specific logs requirements:
What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
The rules in this section apply to shipments of paper rolls, which individually or together, weigh 2268 kg (5000 lb.) or more.
Note: Shipments of paper rolls that weigh less than 2268 kg (5000 lb.), and paper rolls that are unitized on a pallet may either be secured in accordance this section or with the general cargo securement requirements
When loaded cement pipe over 45 inches in diameter, which pipes should be blocked, wedged, or otherwise immobilized?
Immobilize the front and rear pipe with on of the following methods:
Requirements for securing heavy vehicles, equipment, and machinery apply at what weight?
The requirements in this section apply to the transportation of heavy vehicles, equipment, and machinery that:
When securing metal coils with eyes vertical, the angle between tiedown and deck, if possible, should be:
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 metal coils, it is acceptable to use nailed blocking or cleats as the sole means to secure:
The use of nailed blocking or cleats as the sole means to secure timbers, chocks or wedges, or a nailed wood cradle, is prohibited.
The aggregate WLL for logs loaded lengthwise must be at least:
The aggregate working load limit for all tiedowns must be no less than 1/6 the weight of the stack of logs.
Note: This requirement is much less than the general requirement of an aggregate working load limit equal to 1/2 the weight of the load. This lowered requirement recognizes that the bunks/stakes help to prevent slippage.
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.
