- Normally up to about 2.5 m (100 in) in length.
- No longer than 4.9 m (16 ft) in length.

Also called:
- Cut-up logs
- Cut-to-length logs

What's in a stack?

Some stacks may be made up of both shortwood and longwood. Any stack that includes shortwood must follow the shortwood securement requirements.
Exception: If shortwood is embedded in load of longwood, it can be treated as longwood.
- It depends on if you are hauling shortwood or longwood
- 4,000 lb
- 1,800 lb
- 50% of cargo weight
From The CDL Manual
- Use tiedowns in combination with bunks, stakes, or standards and bolsters to secure the load.
- 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.
- 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.
- Each inside log on the side of a stack of logs must touch at least two bunks, bolsters, stakes, or standards.
- Logs must be loosely packed.
From The CDL Manual
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.

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.
- 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.
From The CDL Manual
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.
- 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.
- Vehicle must be divided by center stakes into sections of staggered length.
From The CDL Manual
Requirements for dividing vehicles over 10m (33 ft)
Vehicles over 10 m (33 ft) must be equipped with center stakes, or comparable devices, to divide it into sections of equal length.
Each tiedown must:
- Secure the highest log on each side of the center stake.
- Be fastened below these logs.
- Heavier logs must be stacked on top.
- Logs should be centered in the bunk.
- Each outside log bearing against stakes should extend at least 6 in beyond the stakes at each end.
- Must be cradled in a bunk or contained by stakes.
From The CDL Manual
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.
- 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.
- They are blocked in the front by a headboard or another stack of logs.
- All of these apply.
From The CDL Manual
One tiedown
A stack can be secured with one tiedown if all logs in the stack less than 3.04 m (10 ft) are:
- Blocked in the front by a headboard strong enough to restrain the load or by another stack of logs.
- Blocked in the rear by the vehicle's end structure or another stack of logs.
- 4,000 lbs
- 1/6 the weight of the stack.
- 1/2 the weight of the stack.
- 1/2 the weight of the load.
From The CDL Manual
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.
