Working Load Limit (WLL)is defined as:

  • The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
  • 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.
  • 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 summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
  • Working Load Limit (WLL):

    "Fully Contained" means:

    • 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).
    • Cargo is placed against a vehicle structure of adequate strength or other cargo so that it cannot shift or tip.
    • A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
    • A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.

    "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.

    • 5,000 lbs.
    • 5% of cargo weight.
    • 50% of cargo weight.
    • 100% of cargo weight.
  • g:

    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.

    Who is responsible for ensuring that the vehicles, anchor points and other securement components are in good working order?

    • The driver and shipper.
    • The shipper and carrier.
    • The carrier and driver
    • The DOT and the FMCSA.

    Cargo Securement Responsibility:

    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.

    • 90 degrees.
    • 180 degrees.
    • 45 degrees.

    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.

    About The New York State Coil Exam

    You must have a New York State coil endorsement if you want to haul metal coils in New York.

    Performance Criteria for Securement Systems:

    Part I: Cargo Securement Performance Criteria

    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 forward force (80% of the cargo weight) represents braking while driving straight ahead.
    • The rearward force (50% of the cargo weight) represents vehicle acceleration or braking in reverse.
    • The side-to-side or lateral force (50% of the cargo weight) represents traveling on a curve, ramp or changing lanes.
    • The vertical force (20% of the cargo weight)) represents cargo vibration during transport. This requirement is satisfied when the cargo is "Fully Contained"

    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).

    • 0.8 g deceleration in the forward direction.
    • 0.5 g deceleration in the rearward direction.
    • 0.5 g acceleration in a side-to-side or lateral direction.
    • 0.2 g vertical acceleration.

    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).

    PART II - Performance Criteria for Components of a Securement System

    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.

    Cargo Securement Terms That Truck Drivers Should Know:

    • Working Load Limit (WLL):

      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.

    • g:

      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.

    • 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.

    • 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).

    Vehicle Structure and Anchor Points

    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.

    Cargo Securement Responsibility

    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.
