Define 'bolster':
- A crosswise load bearing structural component, particularly a part of a log bunk.
- 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.
- An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
Bolster:
A crosswise load bearing structural component, particularly a part of a log bunk.
Which of the following is not a requirement for shortwood loaded lengthwise?
- Must be cradled in a bunk or contained by stakes.
- Each outside log bearing against stakes should extend at least 6 in beyond the stakes at each end.
- Logs should be centered in the bunk.
- Heavier logs must be stacked on top.
Requirements for shortwood loaded lengthwise
- Shortwood must be cradled in a bunk or contained by stakes.
- Logs should be centered in the bunk.
- Each outside log bearing against stakes should extend at least 0.15 m (6 in) beyond the stakes at each end.
When securing paper rolls with friction mats as a primary method:
- Make sure friction mats are completely covered by the roll.
- The friction mat should stick out from underneath the roll in the opposite direction for which it is providing securement.
- The friction mat should stick out from underneath the roll in the direction it is providing securement.
- All of these answers.
Requirements for friction mats
If a friction mat is used to provide the principal securement for a paper roll, insert the friction mat so that it sticks out from beneath the footprint of the roll in the direction in which it is providing securement.
All of the following are requirements for transporting coils with eyes crosswise except:
- Prevent the coil from rolling
- These are all requirements
- Attach one tiedown rearward
- Attach one tiedown forward
There are three requirements for coils transported with eyes crosswise:
Prevent the coil from rolling
Attach one tiedown forward.
Attach one tiedown rearward.
When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group,lengthwise tiedowns should be either one 1/2 in chain or wire rope, or:
- Two 1/4 inch chains or wire ropes.
- Two 3/8 inch chains or wire ropes.
- One 3/8 inch chain or wire rope.
- Two nylon straps with aggregate WLL of 50% the weight of the load.
As a group
Place lengthwise tiedowns over the group of pipes:
Either one 13 mm (1/2 in) chain or wire rope,
Or two 10 mm (3/8 in) diameter chain or wire rope
To satisfy general cargo securement requirements, what is the minimum WLL for securing vehicles under 10,000 lbs?
- 10,000 lbs.
- 50% of the weight of the cargo.
- 30% of the weight of the cargo.
- 4,500 lbs.
Note: More tiedowns may be required to satisfy the general cargo securement requirements. The Standard states: "The sum of the working load limits from all tiedowns must be at least 50% of the weight of the cargo."
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.
