Special Circumstances: Loading and Securing Paper Rolls on a Flatbed Vehicle or a Curtain-Sided Vehicle

Requirements for eyes vertical or with eyes horizontal and lengthwise

Load and secure the paper rolls as described for a sided vehicle.

Attach tiedowns to secure entire load according to the general cargo securement requirements in Section 2.

Note: Stacked loads of paper rolls with eyes vertical are prohibited

Inspect Cargo and Securing devices:

• Pre-Trip: Yes
• Within first 50 mi: Yes
• When duty status of driver changes: Yes
• At 3 hour intervals or every 150 mi, whichever is first: Yes

Each cargo securement system must be able to withstand a minimum amount of force in each direction.

• Forward Force = 80% of cargo weight when braking while driving straight ahead.
• Rearward Force = 50% of cargo weight when accelerating, shifting gears while climbing a hill, or braking in reverse.
• Sideways Force = 50% of cargo weight when turning, changing lanes, or braking while turning.
• Upward Force = 20% of cargo weight when traveling over bumps in the road or cresting a hill.
  • This requirement is satisfied when the cargo is "Fully Contained."

Situation #4

• A paper roll or the forwardmost roll(s) in a group of paper rolls is not prevented from tipping or falling forward by vehicle structure or other cargo.
• Paper roll width is more than 1.25 times and less than 1.76 times its diameter.
• Only friction mats are used for forward securement.

Solution #4:

The friction mat alone is adequate. The friction mat allows the roll to slide on the floor without tripping the roll.

How strong must the vehicle structure and anchor points be?

All elements of the vehicle structure and anchor points must be strong enough to withstand the forces described on page 7.

• Forward force: 0.8 g (80%)
• Rearward force: 0.5.g (50%)
• Sideways force: 0.5 g (50%)
• Upward force: 0.2 g (20%)

Special Circumstances: Securing a Non-Cubic Shaped Boulder with an Unstable Base

The securement of a non-cubic shaped boulder with an unstable base must meet these requirements in addition to the other large boulder requirements in Section 13.

Surround the top of each boulder at a point between 1/2 and 2/3 of its height with one chain.

The WLL of the chain must be at least 50% of the weight of the boulder.

Attach four chains to the surrounding chain and the vehicle to form a blocking mechanism that prevents any horizontal movement.

Each chain must have a WLL of at least 25% the weight of the boulder, and the angle of the chain must be less than 45° from the horizontal.

Friction mat:

A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.

Stacked Loads

• Load paper rolls on a second layer only if the bottom layer extends to the front of the vehicle.
• Prevent forward, rearward, or side-to-side movement:
  • Either by the same means required for the bottom layer
  • Or by the use of a blocking roll from a lower layer.
• A roll in the rearmost row of any layer must not be raised using dunnage.

The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
