Quote 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.
- Must be cradled in two or more bunks or contained by stakes.
- Secure each log with at least two tiedowns if shorter logs are carried on top of the stack.
- Each end of the log should extend at least 3 inches beyond the stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
Quote From The CDL Manual:
Requirements for securing longwood loaded lengthwise
- Longwood must be cradled in two or more bunks or contained by stakes.
- Each outside log should bear against at least two stakes, one near each end of the log.
- Each end of the log should extend at least 0.15 m (6 in) beyond the stakes.
- If shorter logs are carried on top of the stack, secure each log with at least two tiedowns.
- 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.
Quote 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.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A waterproof sheet used to cover cargo.
- A vertical barrier across a vehicle to prevent forward movement of cargo.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")

- Must be cradled in a bunk or contained by stakes.

- Heavier logs must be stacked on top.
- Each outside log bearing against stakes should extend at least 6 in beyond the stakes at each end.

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.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- A tapered piece of material, thick at one end and thin at the other.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.

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.
- A crosswise load bearing structural component, particularly a part of a log bunk.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
