Go!When securing rolls of paper with eyes vertical, how many points of contact are required to consider a roll secure?
Usually the roll is secure if a paper roll has 3 well-separated points of contact with the vehicle, other rolls, or other cargo.
One option of positioning bundles of building materials is:
Choose one of two options for positioning bundles:
Place bundles in direct contact with each other.
Provide a means (such as dunnage or blocking) to prevent the bundles from shifting towards each other.
The Aggregate Working Load Limit should, at minimum, be:
The aggregate working load limit of any securement system must be at least 50% of the weight of the cargo being secured.
While driving, the freight must not:
When securing concrete pipe up to 45 inches loaded crosswise, tiedowns through the pipe must be:
What is a rub rail?
A rail along the side of a vehicle that protects the side of the vehicle from impacts.
High friction securement devices include:
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
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.
Banding is:
A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
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.
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.
