How many tiedowns are required on a stack of shortwood loaded crosswise?

• 3
• 1
• It depends on the weight

Tiedowns requirements

Use two tiedowns to secure one stack of shortwood loaded crosswise.

Attach the tiedowns to the vehicle frame at the front and rear of the load.

Position tiedowns approximately 1/3 and 2/3 of the length of the logs.

Requirements for securing two stacks of shortwood loaded side-by-side include:

• At least one tiedown is used lengthwise across each stack.
• The highest log is no more than 8 ft above the deck.
• There is no space between the stacks of logs.
• All of these are required.

Additional requirements securement for two stacks side-by-side

In addition to the requirements for shortwood loaded crosswise, load two stacks side-by-side so that:

• There is no space between the stacks of logs.
• The outside of each stack is raised at least 2.5 cm (1 in) within 10 cm (4 in) of the end of the logs or from the side of the vehicle.
• The highest log is no more than 2.44 m (8 ft) above the deck.
• At least one tiedown is used lengthwise across each stack.

Define 'bolster':

• 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.
• A crosswise load bearing structural component, particularly a part of a log bunk.

What is bell pipe concrete?

• Concrete used to make bell pipe.
• Pipe whose flanged end is of smaller diameter than its barrel.
• Pipe used to make concrete bells.
• Pipe whose flanged end is of larger diameter than its barrel.

All of the following are requirements for dividing vehicles over 33ft except:

• Vehicle must be divided by center stakes into sections of staggered length.
• Each tiedown must secure the highest log on each side of the center stake.
• Vehicle must be equipped with center stakes or comparable devices.
• Each tiedown must be fastened below the logs on each side of the center stake.

Banding is:

• 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).
• A device placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tie-down and/or cargo from damage, and to allow the tiedown to slide freely when being tensioned.
• Material used to fill a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
• A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")

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.
• Each inside log on the side of a stack of logs must touch at least two bunks, bolsters, stakes, or standards.
• Outer bottom logs must be in contact with and rest solidly against bunks, bolsters, stakes, or standards.
• Logs must be loosely packed.
