In cargo securement, a wedge is defined as:
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A tapered piece of material, thick at one end and thin at the other, used to help keep cargo from moving.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Wedge:

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:
- Cleat
- Bulkhead
- Void filler
- Stake pocket
Stake Pocket:
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.
In terms of cargo securement, what is a 'well'?
- 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.
- The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- 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.
Well:
The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
When securing concrete pipe loaded crosswise, arrange the top tier:
- As a complete tier.
- Any of these are acceptable.
- As a partial tier in one group.
- As a partial tier in two groups.
Requirements for arranging the top tier
Arrange the top tier as a complete tier, a partial tier in one group, or a partial tier in two groups.
Methods of securing building materials against forward motion include:
- Placing bundles against the bulkhead or front end.
- These are all valid methods.
- Using tiedowns.
- Employing blocking equipment.
-
Option #1
Place bundles against bulkhead/front end structure.
-
Option #2
When different tiers need to be secured, use a combination of blocking equipment and tiedowns.
If you were instructed to 'tarp' a load, what would you be using?
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself.
- A platform or tray on which cargo is placed so that it can be handled as an article.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A waterproof sheet used to cover cargo.
Tarp:
A waterproof sheet used to cover cargo.
Aggregate Working Load Limit is defined as:
- The maximum weight of a load of rocks that a securement device can withstand.
- 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).
- 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.
Aggregate Working Load Limit:
The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
About The Flatbed Cargo Securement CDL Manual
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:
- What is the minimum Working Load Limit of a tiedown used to secure logs?
- What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- What is a cab shield?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- What is a dunnage bag?
- Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- How many tiedowns are required on a stack of shortwood loaded crosswise?
- What is the minimum working load limit of each tiedown used to secure crushed or flattened vehicles?
- Define 'bolster'
- What is a hook-lift container?
- When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
What is a securing device?
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
- Synthetic Webbing
- Chain
- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches
- Blocking
- Front-end structure
- Grab hooks
- Binders
- Shackles
- Winches
- Stake pockets
- D-rings
- Webbing ratchet
- Bracing
- Friction mat
What is a tiedown?
A combination of securing devices that forms an assembly that:
- Attaches cargo to, or restrains cargo on a vehicle.
- Is attached to anchor point(s).
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.
Related Cargo Securement Terms That Every Driver Should Know:
-
Tiedown:
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).
-
Contained:
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.
-
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
How should tiedowns be attached?
Tiedowns can be used in two ways:
-
Attached to the cargo:
- Tiedowns attached to the vehicle and attached to the cargo.
- Tiedowns attached to the vehicle, pass through or aroundan article of cargo, and then are attached to the vehicle again.
-
Pass over the cargo:
- Tiedowns attached to the vehicle, passed over the cargo, and then attached to the vehicle again.
Tiedown placement:
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.
