Go!When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- Rearward
- It doesn't matter
- Straight up and down
- Forward
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 rows of coils, requirements include all of the following except:
- Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.
- Attach at least one tiedown through the center of each row of coils.
- Use blocking or friction mats to prevent forward movement.
- Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
Tiedowns
Attach at least one tiedown over the top of each coil or side-by-side row, located near the front of the coil.
Attach at least one tiedown over the top of each coil or side-by-side row, located near the rear of the coil.

- Upward force: 0.2 g (20%)
A tiedown is defined as:
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- 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).
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.

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.
In cargo securement, what is a 'cleat' defined as?
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- Part of the structure, fitting, or attachment on a vehicle or cargo to which a tiedown is attached.
- A tapered piece of material, thick at one end and thin at the other.
- A short piece of material, usually wood, nailed to the deck to reinforce blocking.
Cleat:
A short piece of material, usually wood, nailed to the deck to reinforce blocking.
An intermodal container is:
- A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
- A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
- A vehicle especially built and fitted with locking devices for transport.

Which of the following are not covered by the specific log securement requirements?
- Loads of no more than four processed logs.
- Logs unitized by banding or other comparable means.
- Firewood, stumps, debris, other short logs, and longer logs.
- None of these are covered by the specific log requirements
The following types of logs are not covered by the specific logs requirements:
- Logs unitized by banding or other comparable means. [Secure according to general cargo securement requirements.]
- Loads of no more than four processed logs. [Secure according to general cargo securement requirements.]
- Firewood, stumps, debris, other short logs, and longer logs. [Transport in a vehicle or container enclosed on both sides, the front, and the rear and strong enough to contain them.]
When securing paper rolls with eyes crosswise, which of the following can be used to prevent side-to-side shifting when there is more than 8 inches of space to the wall?
- Friction mats.
- Tiedowns.
- Any of these methods are acceptable.
- Void fillers.
Requirements for eyes crosswise: prevent rolls from shifting toward either wall
If there is more than a total of 203 mm (8 in) of space between the ends of a paper roll and other rolls or the walls of the vehicle, use one of these methods:
- Void fillers (such as honeycomb)
- Blocking
- Bracing

One option of positioning bundles of building materials is:
- Lean them against each other.
- Lean them to the outside.
- Turn them so only their corners are touching.

- What is the minimum working load limit of each tiedown used to secure crushed or flattened vehicles?
- 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?
Any device specifically manufactured to attach or secure cargo to a vehicle or trailer:
- Synthetic Webbing
- Chain
- Wire rope
- Manila rope
- Synthetic rope
- Steel strapping
- Clamps and latches
- Blocking
- Front-end structure
- Grab hooks
- Binders
- Shackles
- Winches
- Stake pockets
- D-rings
- Webbing ratchet
- Bracing
- Friction mat
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.
