Go!A bulkhead is defined as:
A vertical barrier across a vehicle to prevent forward movement of cargo.
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.).
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:
What is the minimum securement requirement for paper rolls with eyes vertical with a width between 1.25 and 1.76 its diameter?
The friction mat alone is adequate. The friction mat allows the roll to slide on the floor without tripping the roll.
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.
When loading paper rolls with eyes horizontal, which of the following is not a requirement for stacking a second layer:
When securing paper rolls on a flatbed or curtainside vehicle, it is acceptable to stack rolls with eyes vertical:
Load and secure the paper rolls as described for a sided vehicle.
Attach tiedowns to secure entire load according to the general cargo securement requirements in Section 2.
Note: Stacked loads of paper rolls with eyes vertical are prohibited
When securing concrete pipe with a diameter of more than 45 inches loaded crosswise, how many tiedowns are required through each pipe at minimum?
Secure each pipe with tiedowns through the pipe.
Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable.
Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
Aggregate Working Load Limit is defined as:
The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
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.
