Must be arranged to prevent sliding across the rock surface.
When securing paper rolls on a flatbed or curtainside vehicle, it is acceptable to stack rolls with eyes vertical:
- When total weight is less than 5,000 lbs.
- When using tiedowns that wrap twice around the load.
- Stacking rolls with eyes vertical is not acceptable
- When temperature is 63 degrees F or more.
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
When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
- Less than 45 degrees.
- It doesn't matter.
- 90 degrees.
- Between 45 and 60 degrees.
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- Straight up and down.
- Forward
- Rearward
- It doesn't matter.
Requirements for securing the pipe
Secure each pipe with tiedowns through the pipe.
Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable.
Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45° with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
When securing a single metal coil with eyes vertical:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- These are all requirements.
- Attach at least one tiedown over eye of coil from side-to-side.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
To prevent the coil from tipping forward, rearward, and sideways, arrange tiedowns to include the following:
- Attach at least one tiedown diagonally across eye of coil from left side of vehicle to right side of vehicle.
- Attach at least one tiedown diagonally across eye of coil from right side of vehicle to left side of vehicle.
- Attach at least one tiedown over eye of coil from side-to-side.
If the cargo is fully contained in a sided vehicle, what is the minimum requirement for withstanding sideways force?
- 0.2g (20% of cargo weight)
- 0.5g (50% of cargo weight)
- 0.7g (70% of cargo weight)
- 0.8g (80% of cargo weight)
Note: If the cargo is contained in a sided vehicle, the vehicle structure MUST be strong enough to withstand the forces described earlier.
- Forward force: 0.8 g (80%)
- Rearward force: 0.5.g (50%)
- Sideways force: 0.5 g (50%)
How many anchor points should be used to secure an intermodal container on a chassis vehicle?
- 4 latches total, anywhere on the trailer.
- 2 latches in the front and 2 in the middle.
- 2 latches each at or near both the front and rear.
- 2 latches in the middle, and 2 at the rear.
Secure the front and rear of the container independently.
- 2 latches on the chassis engage anchor points towards or at the front of the container.
- 2 latches on the chassis engage anchor points towards or at the rear of the container.
When securing paper rolls with eyes vertical in a sided vehicle all of the following are acceptable except:
- Placing the rolls against each other.
- Placing rolls against the doors.
- Placing rolls against the front and walls of the vehicle.
- Placing the rolls against other cargo.

- Define 'bolster'
- What is a hook-lift container?
- When a tiedown is attached directly to the cargo, what is the ideal angle where it attached to the vehicle?
What is a securing device?

- Synthetic Webbing
- Chain
- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches
- Blocking
- Front-end structure
- Grab hooks

What is a tiedown?
A combination of securing devices that forms an assembly that:
- Attaches cargo to, or restrains cargo on a vehicle.
- Is attached to anchor point(s).
Some tiedowns are attached to the cargo and provide direct resistance to restrain the cargo from movement.
Some tie-downs pass over or through the cargo. They create a downward force that increases the effect of friction between the cargo and the deck. This friction restrains the cargo.
Related Cargo Securement Terms That Every Driver Should Know:
-
Tiedown:
A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
-
Contained:
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
-
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
How should tiedowns be attached?
Tiedowns can be used in two ways:
-
Attached to the cargo:
- Tiedowns attached to the vehicle and attached to the cargo.
- Tiedowns attached to the vehicle, pass through or aroundan article of cargo, and then are attached to the vehicle again.
-
Pass over the cargo:
- Tiedowns attached to the vehicle, passed over the cargo, and then attached to the vehicle again.
Tiedown placement:
Place the tiedown as close as possible to the spacer.
Position the tiedowns as symetrically as possible over the length of the article.
Position the tiedowns to preserve the integrity of the article.
