Working Load Limit (WLL)is defined as:

• The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2).
• 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.
• The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
• The number of hours that a tiedown can be used.

Which of the following is not true of Working Load Limit (WLL)?

• All of these are true.
• The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system.
• The WLL is usually assigned by the component manufacturer.
• The minimum WLL requirement for the securement system is 25%.

To secure paper rolls with eyes horizontal against rearward movement, you can use which of the following except:

• Blocking.
• The vehicle wall.
• Friction mats.
• Other cargo.

When banding paper rolls with eyes vertical, you should:

• Secure bands with tape, hangers, or other means.
• Spread rolls apart from each other.
• All of these are necessary.
• Apply bands loosely.

Banding

If paper rolls are banded together:

• Place rolls tightly against each other to form a stable group.
• Apply bands tightly.
• Secure bands with tape, hangers, or other means so that the bands cannot fall off the rolls or slide down to the deck.

The term 'edge protector' refers to:

• A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
• A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.
• A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
• A rail along the side of a vehicle that protects the side of the vehicle from impacts.

In terms of cargo securement, what is a 'well'?

• The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
• 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.
• 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 rail along the side of a vehicle that protects the side of the vehicle from impacts.

Who is responsible for inspecting securing devices and cargo within the first 50 miles?

• The D.O.T.
• Your Moms.
• The driver.
• The shipper.

How much force is the securement system required to withstand in terms of cargo weight?

• 50% forward, 20% rearward, 50% sideways, 20% upwards.
• 80% forward, 50% rearward, 50% sideways, 20% upwards.
• 80% forward, 50% rearward, 80% sideways, 20% upwards.
• 50% forward, 50% rearward, 50% sideways, 80% upwards.

An anchor point is defined as:

• The load carrying area of a truck, trailer, or intermodal container.
• Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
• A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
• A rail along the side of a vehicle that protects the side of the vehicle from impacts.

To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?

• 1
• 3
• 2
• 5

Special Circumstances: Securing a Cubic-Shaped Boulder

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.
