SECTION 2: GENERAL PROVISIONS AND REQUIREMENTS

Purpose of Indirect Tiedowns

The purpose of the indirect tiedown is to increase the pressure of the article on the deck (that is, to increase the frictional force between the article and the deck).

An indirect tiedown has failed if the article shifts. If friction is low between the deck and the cargo (such as a plastic skid, plastic-coated article, or an oilsoaked/ wet deck), direct tiedowns can be more effective. Under these conditions, consider using friction mats or other friction enhancing devices.

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.

An indirect tiedown should be tensioned to as high an initial tension as possible, at least 50% of its working load limit. The tension should be maintained throughout the trip.

Calculating Working Load Limits for Indirect Tiedowns:

Each tiedown that passes over an article is considered to be 1 tiedown.

The aggregate working load limit of all indirect tiedowns is the sum of the working load limits of each indirect tiedown.

In this picture, if each tiedown has a working load limit of 4,000 lbs. (1,820 kgs.), the aggregate working load limit for this securement system is 8,000 lbs. (3,640 kgs.).

Cargo Securement Terms That Truck Drivers Should Know:

  • Intermodal Container:

    A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.

  • Bulkhead:

    A vertical barrier across a vehicle to prevent forward movement of cargo.

  • Hook-lift Container:

    A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.

  • Well:

    The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.

CDL:

Commercial Driver's License (CDL)

A CDL is required to drive any of the following vehicles:

  • Any combination of vehicles with a gross combined weight rating (GCWR) of 26,001 or more pounds, providing the gross vehicle weight rating (GVWR) of the vehicle being towed is in excess of 10,000 pounds.
  • Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing another not in excess of 10,000 pounds.
  • Any vehicle, regardless of size, designed to transport 16 or more persons, including the driver.
  • Any vehicle required by federal regulations to be placarded while transporting hazardous materials.

Bulkhead:

A strong wall-like structure placed at the front of a flatbed trailer (or on the rear of the tractor) used to protect the driver against shifting cargo during a front-end collision. May also refer to any separator within a dry or liquid trailer (also called a baffle for liquid trailers) used to partition the load.

Intermodal:

Transporting freight using two or more transportation modes. An example would be freight that is moved by truck from the shipper's dock to the rail yard, then placed on a train to the next rail yard, and finally returned to a truck for delivery to the receiving customer.

In trucking when you hear someone refer to an intermodal job they're normally talking about hauling shipping containers to and from the shipyards and railyards.

A 'hook-lift container' is:
  • A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
  • A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
  • A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
  • A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")

    • The depression formed between two cylindrical articles when they are laid with their eyes horizontal and parallel against each other.
    • A vertical barrier across a vehicle to prevent forward movement of cargo.
    • A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
