- A tapered piece of material, thick at one end and thin at the other.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Cleat:
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Which of the following are not covered by the specific log securement requirements?
- Firewood, stumps, debris, other short logs, and longer logs.
- None of these are covered by the specific log requirements
- Logs unitized by banding or other comparable means.
- Loads of no more than four processed logs.
The following types of logs are not covered by the specific logs requirements:
- Logs unitized by banding or other comparable means. [Secure according to general cargo securement requirements.]
- Loads of no more than four processed logs. [Secure according to general cargo securement requirements.]
- Firewood, stumps, debris, other short logs, and longer logs. [Transport in a vehicle or container enclosed on both sides, the front, and the rear and strong enough to contain them.]
Securing heavy vehicles or equipment with crawler tracks or wheel requires a minimum of how many tiedowns?
- It depends on the weight of the load
- 6
- 2
- 4
Special Circumstances: Securing Heavy Vehicles, Equipment, or Machinery with Crawler Tracks or Wheels
Tiedown requirements
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
- Prevents cargo movement in the side-to-side, forward, rearward, and vertical directions.
-
Attach tiedowns:
- Either at the front and rear of the vehicle.
- Or at the mounting points on the vehicle designed for that purpose.
What is the minimum aggregate WLL of all tiedowns in a group of concrete pipe?
- 5,000 lbs.
- It depends on the size of the 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.
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.
Aggregate Working Load Limit is defined 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.
- 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 summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- The maximum weight of a load of rocks that a securement device can withstand.
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.
What is the presumed resistance to horizontal movement of friction mats?
- 100% of cargo weight.
- 20% of cargo weight.
- 50% of cargo weight.
- 0
Note: Friction mats, which are not marked by the manufacturer, are assumed to provide a resistance to horizontal movement equal to 50% of the cargo weight that is resting on the mat.
'Blocking' is defined as:
- 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 structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- 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.
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.
