Safety Administration’s

applicable to the transportation of logs with the

following exceptions:

(1) Logs that are unitized by banding or other

comparable means may be transported in

accordance with the general cargo securement

rules of §§393.100 through 393.114.

(2)Loads that consist of no more than four

processed logs may be transported in

accordance with the general cargo securement

rules of §§393.100 through 393.114.

(3)Firewood, stumps, log debris and other such

short logs must be transported in a vehicle or

container enclosed on both sides, front, and rear

and of adequate strength to contain them.

Longer logs may also be so loaded.

(1)Logs must be transported on a vehicle

designed and built, or adapted, for the

transportation of logs. Any such vehicle must

be fitted with bunks, bolsters, stakes or

standards, or other equivalent means, that

cradle the logs and prevent them from rolling.

(2)All vehicle components involved in securement

of logs must be designed and built to withstand all

anticipated operational forces without failure,

accidental release or permanent

deformation. Stakes or standards that are

not permanently attached to the vehicle

must be secured in a manner that prevents

unintentional separation from the vehicle

in transit.

(3)Tiedowns must be used in combination with the

stabilization provided by bunks, stakes and

bolsters to secure the load.

(1)Logs must be solidly packed, and the outer

bottom logs must be in contact with and

resting solidly against the bunks, bolsters,

stakes or standards.

(2)Each outside log on the side of a stack of

logs must touch at least two stakes, bunks,

bolsters, or standards. If one end does not

actually touch a stake, it must rest on other logs

in a stable manner and must extend beyond the

stake, bunk, bolster or standard.

(3)The center of the highest outside log on each

side or end must be below the top of each stake,

bunk or standard.

(4)Each log that is not held in place by contact with

other logs or the stakes, bunks, or standards

must be held in place by a tiedown. Additional

tiedowns or securement devices must be used

when the condition of the wood results in such

low friction between logs that they are likely to

slip upon each other.

requirements of paragraphs (b) and (c) of this

section, each stack of logs loaded crosswise must

meet the following rules:

(1)In no case may the end of a log in the lower tier

extend more than one-third of the log’s total

length beyond the nearest supporting structure

on the vehicle.

(2)When only one stack of shortwood is loaded

crosswise, it must be secured with at least two

tiedowns. The tiedowns must attach to the

vehicle frame at the front and rear of the load,

and must cross the load in this direction.

(3)When two tiedowns are used, they must be

positioned at approximately one-third and twothirds

of the length of the logs.

(4)A vehicle that is more than 10 meters (33 feet)

long must be equipped with center stakes, or

comparable devices, to divide it into sections

approximately equal in length. Where a vehicle

is so divided, each tiedown must secure the

highest log on each side of the center stake, and

must be fastened below these logs. It may be

fixed at each end and tensioned from the

middle, or fixed in the middle and tensioned

from each end, or it may pass through a pulley

or equivalent device in the middle and be

tensioned from one end.

(5)Any structure or stake that is subjected to an

upward force when the tiedowns are tensioned

must be anchored to resist that force.

(6)If two stacks of shortwood are loaded side-byside,

in addition to meeting the requirements of

paragraphs (d)(1) through (d)(5) of this

section, they must be loaded so that:

(i)Ther e is no space between the two stacks

of logs;

(ii)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 the side of the vehicle;

(iii)The highest log is no more than 2.44 m (8 ft)

above the deck; and

(iv)At least one tiedown is used lengthwise

across each stack of logs.

requirements of paragraphs (b) and (c) of this

section, each stack of shortwood loaded lengthwise

on a frame vehicle or on a flatbed must be secured

to the vehicle by at least two tiedowns.

(1)The load must be secured by at least one

tie down at each bunk, or alternatively, by at

least two tie downs used as wrappers that

encircle the entire load at locations along the

load that provide effective securement.

(2)The front and rear wrappers must be at least

3.04 meters (10 feet) apart.

(3)Large diameter single and double log loads

must be immobilized with chock blocks or other

equivalent means to prevent shifting.

(4)Large diameter logs that rise above bunks must

be secured to the underlying load with at least

two additional wrappers.
