Go!What is the maximum weight that can be secured by a tiedown with a marked WLL of 5,000 lbs?
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
Working Load Limit (WLL)is defined as:
The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces is:
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
A chock is defined as:
A tapered or wedge-shaped piece used to secure round articles against rolling.
All of the following are requirements for dividing vehicles over 33ft except:
Vehicles over 10 m (33 ft) must be equipped with center stakes, or comparable devices, to divide it into sections of equal length.
Each tiedown must:
When securing paper rolls with eyes horizontal, which of the following should be used to secure the rear-most roll?
Note: Chocks, Wedges, or Blocking Securing the Front or Rear Roll - Hold in place by some means in addition to friction so they cannot become unintentionally unfastened or loose while the vehicle is in transit. This is often accomplished with nails.
Do not secure the rearmost roll with:
Securing heavy vehicles or equipment with crawler tracks or wheel requires a minimum of how many tiedowns?
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.
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:
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.
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.
