Go!When loaded cement pipe over 45 inches in diameter, which pipes should be blocked, wedged, or otherwise immobilized?
Immobilize the front and rear pipe with on of the following methods:
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.
If you were instructed to 'tarp' a load, what would you be using?
A waterproof sheet used to cover cargo.
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.).
All of these are requirements for securing longwood lengthwise except:
As part of their pre-trip cargo securement inspection, drivers should:
What is the minimum WLL of a tiedown used to secure logs?
Load securement for cargo weighing 29,650 lbs must be able to withstand upward force of how many lbs?
All elements of the vehicle structure and anchor points must be strong enough to withstand the forces described on page 7.
Which of these are requirements for securement systems?
The aggregate WLL for logs loaded lengthwise must be at least:
The aggregate working load limit for all tiedowns must be no less than 1/6 the weight of the stack of logs.
Note: This requirement is much less than the general requirement of an aggregate working load limit equal to 1/2 the weight of the load. This lowered requirement recognizes that the bunks/stakes help to prevent slippage.
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.
