A stack of shortwood loaded lengthwise can be secured with one tiedown if:
- They are blocked in the front by a headboard or another stack of logs.
- All of these apply.
- They are blocked in the back by the vehicle's end structure or another stack of logs.
- All logs in the stack are less than 10 ft long.
One tiedown
A stack can be secured with one tiedown if all logs in the stack less than 3.04 m (10 ft) are:

- All tiedowns must have a working load limit not less than 1,800 kg (4,000 lb.).
- Tension tiedowns as tightly as possible but not beyond their working load limit.
An anchor point is defined as:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- The load carrying area of a truck, trailer, or intermodal container.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Anchor point:
Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
Requirements for securing a non-cubic shaped boulder with a stable base include all of the following except:
- Pass the tiedowns over the center of the boulder
- Attach chains together at the intersection
- Secure each boulder individually with at least two chain tiedowns forming an X pattern over the boulder.
- Wrap chains around the circumference of the boulder.
Secure each boulder individually with at least two chain tiedowns forming an X pattern over the boulder.
Pass the tiedowns over the center of the boulder and attach them to each other at the intersection by a shackle or other connecting device.
Define 'bolster':
- A crosswise load bearing structural component, particularly a part of a log bunk.
- 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.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
Bolster:
A crosswise load bearing structural component, particularly a part of a log bunk.
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.
