A container chassis vehicle is defined as:
A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
What is the presumed resistance to horizontal movement of friction mats?
Note: Friction mats, which are not marked by the manufacturer, are assumed to provide a resistance to horizontal movement equal to 50% of the cargo weight that is resting on the mat.
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 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.
What is the minimum aggregate WLL for a group of concrete pipe weighing 16,000 lbs?
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.
A dunnage bag is:
An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point is a:
A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
Methods of securing building materials against forward motion include:
Place bundles against bulkhead/front end structure.
When different tiers need to be secured, use a combination of blocking equipment and tiedowns.
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.
