Go!Securing heavy vehicles or equipment with crawler tracks or wheel requires a minimum of how many tiedowns?
In cargo securement, what is a 'cleat' defined as?
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
When securing a non-cubic boulder with an unstable base, the four surrounding chains must have a WLL of at least:
The securement of a non-cubic shaped boulder with an unstable base must meet these requirements in addition to the other large boulder requirements in Section 13.
Surround the top of each boulder at a point between 1/2 and 2/3 of its height with one chain.
The WLL of the chain must be at least 50% of the weight of the boulder.
Attach four chains to the surrounding chain and the vehicle to form a blocking mechanism that prevents any horizontal movement.
Each chain must have a WLL of at least 25% the weight of the boulder, and the angle of the chain must be less than 45° from the horizontal.
In terms of cargo securement, what is a 'well'?
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
Cargo securement for a load weighing 37,000 lbs must be able to withstand a minimum forward braking force of:
Each cargo securement system must be able to withstand a minimum amount of force in each direction.
How much force is the securement system required to withstand in terms of cargo weight?
All elements of the vehicle structure and anchor points must be strong enough to withstand the forces described on page 7.
What is the minimum number of tiedowns to use on a load 4ft 7in long, and weighing 1,237 lbs?
Minimum number of tiedowns: 1
Minimum number of tiedowns: 2
Minimum number of tiedowns: 2
The maximum distance from the rear allowed for attaching mechanisms used to secure roll-on/roll-off containers is:
Attach mechanisms used to secure the rear end of a roll-on/roll-off or hook lift container no more than two meters (6.5 feet) from the rear of the container.
When securing building materials, how many knots are acceptable in the tiedown(s)?
Methods to keep a cradle from sliding include:
Prevent the coil from rolling by supporting it:
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.
