Logs loaded lengthwise on these vehicles must meet these requirements in addition to the other logs requirements.
Secure each stack of short wood with at least two tie-downs.
A stack can be secured with one tie down if all logs in the stack less than 3.04 m (10 ft) are:
Position the one tie down about midway between bunks, stakes, or standards.
The aggregate working load limit for all tie-downs 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.
Either at least one tie down at each bunk.
Or at least two tie-downs used as wrappers that encircle the entire load.
Position front and rear wrappers at least 3.04 m (10 ft) apart.
Use chock blocks to prevent the shifting of large diameter single and double log loads.
Secure large diameter logs that are above the bunks to the underlying load with at least two additional wrappers.
A tapered or wedge-shaped piece used to secure round articles against rolling.
A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
All of these are requirements for securing longwood lengthwise except:
The aggregate WLL for logs loaded lengthwise must be at least:
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.
A chock is defined as:
A tapered or wedge-shaped piece used to secure round articles against rolling.
In cargo securement, what is a 'cleat' defined as?
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
What is a pallet used for?
A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
Which of the following is not a requirement for shortwood loaded lengthwise?
A stack of shortwood loaded lengthwise can be secured with one tiedown if:
A stack can be secured with one tiedown if all logs in the stack less than 3.04 m (10 ft) are:
When securing a load of lengthwise longwood logs weighing 42,500 lbs, what is the minimum aggregate WLL required for tiedowns? (rounded up to nearest lb)
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.
