Go!What is a headboard?
- A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A transverse load bearing structural component, particularly a part of a log bunk.
- A vertical barrier across a vehicle to prevent forward movement of cargo.
Headboard:
A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Concrete pipe loaded crosswise generally:
- At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
- Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
- Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
- All of these things apply.
Special Circumstances: Securing Pipe with an Inside Diameter Up to 1.143 mm (45 in)
Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
Note: This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe.
Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
When securing a single metal coil with eyes vertical:
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
- These are all requirements.
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
To prevent the coil from tipping forward, rearward, and sideways, arrange tiedowns to include the following:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
What is the minimum aggregate WLL of all tiedowns in a group of concrete pipe?
- 80% of the total weight of all pipes in the group.
- More than 50% of the total weight of all pipes in the group.
- It depends on the size of the pipe.
- 5,000 lbs.
General tiedown requirements
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.
Methods of securing building materials against forward motion include:
- These are all valid methods.
- Placing bundles against the bulkhead or front end.
- Employing blocking equipment.
- Using tiedowns.
-
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.
What is the maximum weight that can be secured by a tiedown with a marked WLL of 5,000 lbs?
- 5,000 lbs
- 10,000 lbs
- 2,500 lbs
- 6,000 lbs
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
Which of these is specifically prohibited when securing crushed or flattened vehicles?
- Wire rope.
- Chains.
- Containment walls.
- Synthetic webbing.
Securement Requirements
Transport flattened or crushed vehicles so that:
- Cargo does not shift while in transit AND
- Loose parts from the flattened vehicles do not dislodge and fall from the transport vehicle
Do not use synthetic webbing to secure vehicles.
Which of the following is not a method of securing side-by-side cargo?
- Place them in direct contact with each other.
- Fill the empty space between with other cargo.
- Use some kind of blocking to prevent shifting.
- Make sure it is leaning forward.
For articles of cargo placed beside each other and secured by side-to-side tiedowns:
Either place them in direct contact with each other,
Or prevent them from shifting towards each other in transit by using blocking or filling the space with other cargo.
What types of freight need to be secured properly?
- Intermodal containers.
- Equipment used for vehicle operation.
- All freight should always be properly secured while driving.
- Hazardous materials.
-
Any cargo and dangerous goods/hazardous materials, including:
- All general freight.
- All equipment carried for vehicle operation.
- Intermodal containers and their contents.
- Some specific commodities have additional or different securement requirements (see later sections of this Handbook).
- Additional requirements under separate regulations may also apply for transportation of certain types of dangerous goods or hazardous materials.
Cargo
Which of the following is not a reason why loads should be secured?
- Avoid fines and citations
- Prevent damage to the cargo
- Make it look pretty
- Prevent loss of load
Why secure your load? To prevent:
- Loss of life
- Loss of load
- Damage to the cargo
- Damage to the vehicle
- Issuance of citations/fines to driver/carrier
- The vehicle being placed Out-of-Service.
- A crash
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.
