When securing rolls of paper with eyes vertical, how many points of contact are required to consider a roll secure?
- 4
- 3
- 1
- 2
Usually the roll is secure if a paper roll has 3 well-separated points of contact with the vehicle, other rolls, or other cargo.
All of the following are requirements for transporting coils with eyes crosswise except:
- Attach one tiedown forward
- Attach one tiedown rearward
- Prevent the coil from rolling
- These are all requirements
There are three requirements for coils transported with eyes crosswise:
Prevent the coil from rolling
Attach one tiedown forward.
Attach one tiedown rearward.
'Blocking' is defined as:
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
When securing heavy vehicles, what is the minimum WLL of each tiedown?
- 5,000 lbs
- 50% of the weight of the cargo
- 2,268 lbs
- 10,000 lbs
- Restrain cargo using a minimum of four tiedowns, each having a WLL of at least 2,268 kg (5,000 lb.).
Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- The driver.
- The shipper.
- Your Moms.
- The D.O.T.
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
When banding paper rolls with eyes vertical, you should:
- Secure bands with tape, hangers, or other means.
- All of these are necessary.
- Spread rolls apart from each other.
- Apply bands loosely.
Banding
If paper rolls are banded together:
- Place rolls tightly against each other to form a stable group.
- Apply bands tightly.
- Secure bands with tape, hangers, or other means so that the bands cannot fall off the rolls or slide down to the deck.
To prevent rolling, how many points of contact are required, at minimum, for a boulder resting on a rounded or partially rounded side?
- 2
- 4
- 3
- 5
Requirements
If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.
Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.
The definition for "shortwood" identifies pieces that are no longer than:
- 75 in
- Half the length of the trailer.
- 16 ft
- The width of the road.
Shortwood
- Normally up to about 2.5 m (100 in) in length.
- No longer than 4.9 m (16 ft) in length.
-
Also called:
- Cut-up logs
- Cut-to-length logs
- Bolts
- Pulpwood
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)
- 10,000 lbs
- 8,550 lbs
- 21,250 lbs
- 7,085 lbs.
Working load limit for longwood and shortwood loaded lengthwise
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.
About The Flatbed Cargo Securement CDL Manual
Studying the flatbed cargo securement CDL manual is not a requirement for getting your CDL permit or license. It is required knowledge for flatbed drivers.
Some questions you should be able to answer for flatbed cargo securement:
- What is the minimum Working Load Limit of a tiedown used to secure logs?
- What is the minimum weight of a shipment of paper rolls that would require specific securement requirements?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the front half of the load run?
- What is a cab shield?
- When securing concrete pipe over 45 inches loaded crosswise, which direction must the tiedowns on the rear half of the load run?
- What is a dunnage bag?
- Who is responsible for inspecting securing devices and cargo within the first 50 miles?
- How many tiedowns are required on a stack of shortwood loaded crosswise?
- 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.
