- It doesn't matter
- Rearward
- 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.
What is the maximum weight that can be secured by a tiedown with a marked WLL of 5,000 lbs?
- 6,000 lbs
- 2,500 lbs

Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
What is the minimum requirement for securing roll-off and hook containers?

-
Rear Mechanism 1:
One tiedown attached to both the vehicle chassis and the container chassis.
-
Rear Mechanism 2:
Two tiedowns installed lengthwise, each securing one side of the container to one of the vehicle's side rails.
-
Rear Mechanism 3:
Two hooks, or an equivalent mechanism, securing both sides of the container to the vehicle chassis at least as effectively as the tiedowns in the two previous items.
What is the minimum WLL of each tiedown used to secure crushed or flattened vehicles?
- 10,000 lbs
- 2,268 lbs
- It depends on the vehicle
- 5,000 lbs
Option 2:
Has containment walls on three sides that:
- Extend to the full height of the load
- Block against cargo movement in the forward, rearward, and one sideways direction.
Secures each stack of vehicles with a minimum of two tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Option 3:
Has containment walls on two sides that:
- Extend to the full height of the load.
- Block against cargo movement in the forward and rearward.
Secures each stack of vehicles with a minimum of three tiedowns, each having a minimum WLL of 2,268 kg (5,000 lb.).
Option 4:
Has a minimum of four tiedowns per vehicle stack with each tiedown having a minimum WLL of 2,268 kg (5,000 lb.).
Which of the following is not true of Working Load Limit (WLL)?
- The WLL is usually assigned by the component manufacturer.
- The minimum WLL requirement for the securement system is 25%.
- The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system.
- All of these are true.
The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service.
The WLL is usually assigned by the component manufacturer.
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.

- 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?

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

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.
