Either they must be crowned
Or each log that is not held in place by contact with other logs or stakes, bunks, or standards must be held in place by a tiedown.
The end of a log in the lower tier must never extend more than 1/3 of the log's total length beyond the nearest supporting structure. This prevents tipping when the vehicle turns.
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.
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:
Option #1: Tiedowns may be fixed at each end and tensioned from the middle.
Option #2: Tiedowns may be fixed in the middle and tensioned from each end.
Tiedowns may pass through a pulley or equivalent device in the middle and tensioned from one end.
Anchor any structure or stake that is being forced upward when the tiedowns are being tensioned.
In addition to the requirements for shortwood loaded crosswise, load two stacks side-by-side so that:
A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
Pipe whose flanged end is of larger diameter than its barrel.
A crosswise load bearing structural component, particularly a part of a log bunk.
What is bell pipe concrete?
Pipe whose flanged end is of larger diameter than its barrel.
Banding is:
A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
How many tiedowns are required on a stack of shortwood loaded crosswise?
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.
Define 'bolster':
A crosswise load bearing structural component, particularly a part of a log bunk.
All of the following are requirements for dividing vehicles over 33ft except:
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:
Requirements for securing two stacks of shortwood loaded side-by-side include:
