Securing Coils Transported in a Sided Vehicle or Intermodal Container without Anchor Points
To prevent metal coils from moving horizontally and/or tipping:
Follow general cargo securement requirements
Secure the coils using:
- Blocking and bracing
- Friction mats
- A combination of these.
Which of the following can be used as part of the cargo securement system?
- Vehicle structure.
- Blocking and bracing equipment.
- All of these are valid.
- Securing devices.
What is a securement system?
A securement system is a securement method that uses one or a combination of the following elements:
- Vehicle Structure.
- Securing Devices.
- Blocking and Bracing Equipment.
When calculating directional forces, 'g' is expressed 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.
- The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
- 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.

When securing paper rolls with eyes vertical in a sided vehicle all of the following are acceptable except:
- Placing the rolls against each other.
- Placing the rolls against other cargo.
- Placing rolls against the front and walls of the vehicle.
- Placing rolls against the doors.
- Place paper rolls together in a group so that the structure of the group can be maintained.
- Place paper rolls against:
- The front and walls of the vehicle
- Each other
- Other cargo
To prevent rolling, how many points of contact are required, at minimum, for a boulder resting on a rounded or partially rounded side?
- 2
- 3
- 5
- 4
Requirements
If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.
Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.
'Blocking' is defined as:
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- 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.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
To secure a cubic-shaped boulder, how many tiedowns are required, at minimum?
- 1
- 5
- 3
- 2
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.
An intermodal container is:
- A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
- A vehicle especially built and fitted with locking devices for transport.
- A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
Intermodal Container:
A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
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.
