As part of the log packing requirements:
- The center of the highest log on each side or end must be above the top of each stake, bunk, or standard.
- Outer bottom logs must be in contact with and rest solidly against bunks, bolsters, stakes, or standards.
- Logs must be loosely packed.
- Each inside log on the side of a stack of logs must touch at least two bunks, bolsters, stakes, or standards.
Packing requirements
- Logs must be solidly packed.
- Outer bottom logs must be in contact with and rest solidly against bunks, bolsters, stakes, or standards.
-
Each outside log on the side of a stack of logs must touch at least two bunks, bolsters, stakes, or standards. If one end of the log doesn't touch a stake:
- It must rest on other logs in a stable manner.
- It must extend beyond the stake, bunk, bolster, or standard.
- The center of the highest log on each side or end must be below the top of each stake, bunk, or standard.
Define 'bolster':
- A crosswise load bearing structural component, particularly a part of a log bunk.
- 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.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Bolster:
A crosswise load bearing structural component, particularly a part of a log bunk.
When securing a load of lengthwise longwood logs weighing 42,500 lbs, what is the minimum aggregate WLL required for tiedowns? (rounded up to nearest lb)
- 8,550 lbs
- 21,250 lbs
- 10,000 lbs
- 7,085 lbs.
Working load limit for longwood and shortwood loaded lengthwise
The aggregate working load limit for all tiedowns must be no less than 1/6 the weight of the stack of logs.
Note: This requirement is much less than the general requirement of an aggregate working load limit equal to 1/2 the weight of the load. This lowered requirement recognizes that the bunks/stakes help to prevent slippage.
How many knots are acceptable in a properly working tiedown?
- 1
- 3
- 0
- 2
All components of a tiedown must be in proper working order.
- No knots or obvious damage
- No distress
- No weakened parts
- No weakened sections
When securing heavy vehicles, what is the minimum WLL of each tiedown?
- 10,000 lbs
- 50% of the weight of the cargo
- 5,000 lbs
- 2,268 lbs
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
Option #1 for securing coils transported with eyes lengthwise includes:
- It should include all of these things
- Attaching at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle
- Attaching at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle
- Using blocking or friction mats to prevent forward movement.
Tiedowns, Single Coil Option #1
Attach at least one tiedown diagonally from the left side of the vehicle, through the eye, to the right side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown diagonally from the right side of the vehicle, through the eye, to the left side of the vehicle. If possible, the angle between the tiedown and the deck should be less than 45, when viewed from the side of the vehicle.
Attach at least one tiedown side-to-side over the top of the coil.
Use blocking or friction mats to prevent forward movement.
What is bell pipe concrete?
- Pipe used to make concrete bells.
- Concrete used to make bell pipe.
- Pipe whose flanged end is of smaller diameter than its barrel.
- Pipe whose flanged end is of larger diameter than its barrel.
Bell Pipe Concrete:
Pipe whose flanged end is of larger diameter than its barrel.
When securing rows of coils, requirements include all of the following except:
- Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.
- Use blocking or friction mats to prevent forward movement.
- Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
- Attach at least one tiedown through the center of each row of coils.
Tiedowns
Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.
Use blocking or friction mats to prevent forward movement.
Working Load Limit (WLL)is defined as:
- The number of hours that a tiedown can be used.
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- 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).
Working Load Limit (WLL):
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.

- 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

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.
