Go!What is the maximum ideal angle for an effective direct tiedown?
A direct tiedown is considered effective against forward and rearward forces if it makes an angle less than 45 degrees when viewed from the side of the vehicle.
A direct tiedown is considered effective against side-to-side forces if it makes an angle less than 45 degrees with the horizontal when viewed from the front or rear of the vehicle.
Whenever possible, a row of metal coils with eyes vertical requires one direct tiedown to secure against rearward movement at what minimum angle?
At least one direct tiedown against the front of the row of coils, restraining against forward motion, and if practicable, making an angle 45 degrees or less with the floor.
At least one direct tiedown against the rear of the row of coils, restraining against rearward motion, and if practicable, making an angle 45 degrees or less with the floor.
A friction mat is used to:
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
In cargo securement, the deck is:
The load carrying area of a truck, trailer, or intermodal container.
A chock is generally used to secure:
A tapered or wedge-shaped piece used to secure round articles against rolling.
When should a driver inspect the cargo and securing devices?
The driver is responsible for the following cargo securement inspection activities:
A load weighing 41,500 lbs requires securement against rearward force of:
Working Load Limit (WLL)is defined as:
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.
What is the minimum number of tiedowns required through the eye of a metal coil loaded crosswise?
At least one direct tiedown is required through its eye, restricting forward motion.
At least one direct tiedown is required through its eye, restricting rearward motion.
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.
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.
