Go!What is the minimum WLL used to block forward movement of cargo weighing 36,500 lbs?
The working load limit of all components used to block cargo from forward movement must be 50% (or more) of the weight of the article being blocked.
A single metal coil with eye vertical weighing 6,350 lbs requires tiedowns with a minimum aggregate WLL of:
The sum of the working load limits from all tiedowns must be at least 50% of the weight of the coils.
What is a cab shield?
A vertical barrier placed directly behind the cab of a tractor to protect the cab in the event cargo should shift forward.
"Fully Contained" means:
"Fully contained" means that the cargo is placed against a vehicle structure of adequate strength or other cargo so that it cannot shift or tip. Cargo that fills a sided vehicle of adequate strength is considered fully contained.
CDL drivers from New York State require the Metal Coils Endorsement when transporting metals coils weighing:
Commercial drivers licensed in New York State are required to get the New York State Metal Coil Endorsement in order to transport a metal coil, or a group of metal coils, weighing more than 5,000 lbs (2,268 kg.)
When should a driver inspect the cargo and securing devices?
The driver is responsible for the following cargo securement inspection activities:
Blocking is used to:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
What is the minimum angle that indirect tiedowns must form with the vehicle?
An indirect tiedown that is used to prevent front-to-back cargo movement must make an angle of at least 30 degrees with the deck when viewed from the side of the vehicle.
An indirect tiedown that is used to prevent side-to-side movement must make an angle of at least 30 degrees when viewed from the front or back of the vehicle.
.5g is equal to what?
The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
How many tiedowns are required for cargo that is prevented from forward movement?
When cargo is prevented from forward movement (for example, by the headboard, bulkhead, other cargo, or tiedown), secure the cargo according to the following requirements:
All Cargo:
1 tiedown for every 10 ft, or part thereof.
You must have a New York State coil endorsement if you want to haul metal coils in New York.
The standard provides the minimum amount of force that cargo should be expected to withstand, in each direction, as shown below.
These minimum force requirements, called the “performance criteria”, were determined after extensive testing. The securement system MUST be capable of resisting these forces, as shown below.
The performance criteria may also be expressed in terms of acceleration, which is shown at right (“g” is the term used for gravity, and represents acceleration or deceleration).
EXAMPLE: If a steel coil weighs 10,000 lbs., the load securement must provide 8,000 lbs. of securement to prevent movement in the forward direction, which is expressed as 80% of the cargo weight (or 0.8 g).
Each component of the cargo securement system should not exceed its Working Load Limit (WLL), when at maximum force. The Working Load Limit is the maximum load that may be applied to a component of a cargo securement system during normal service; it is usually assigned by the manufacturer of the component.
Each force in the performance criteria is to be applied separately to the securement system to determine if it is compliant.
The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2). For cargo securement purposes it is expressed as a percentage of cargo weight, i.e. .5g is 50% of force of gravity or 50% of cargo weight.
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.
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).
The vehicle must be strong enough to resist the forces in the performance criteria (Section 1). The vehicle must be appropriate for the cargo it is to transport, or it must be adapted to be suitable by using fittings, fixtures, dunnage, cribbing or other means.
According to federal and state regulations, the carrier and driver are responsible for ensuring that the vehicles, anchor points and other securement components are in good working order, with no obvious signs of damage. The driver is also required to conduct a pre-trip inspection by other operating regulations.
Roadside inspections are conducted in accordance with federal, state and provincial laws. If securement equipment fails inspection, it is likely that the vehicle may be placed out-of-service, and the motor carrier and/or the driver may be fined.
