Study Notes

Intermodal Containers

  • Intermodal containers are transported on various vehicles (chassis or non-chassis)
  • Securing procedures differ depending if the container is loaded, empty, or on a chassis or non-chassis vehicle
  • Loaded containers on chassis vehicles require securing using at least two latches on the chassis engage anchor points, on the front and rear of the container.
  • Loaded containers on non-chassis vehicles should be secured by chains, wire ropes, or integral locking devices to all lower or upper corners of the vehicle.
  • Containers must be secured to prevent:
    • Movement more than 1.27 cm (1/2 inch) forward or backward
    • Movement more than 1.27 cm (1/2 inch) to the left or right
    • Movement more than 2.54 cm vertically (1 inch)
  • Securing devices should be independently attached, and cannot come loose unintentionally.
  • If a latch breaks or goes missing use alternative securing methods (e.g. chain, wire rope)
  • When securing cargo inside an intermodal container, follow general cargo requirements or specific cargo guidelines.
  • Empty containers on non-chassis carriers must meet four requirements:
    • Balanced and stable positioning.
    • Cannot hang over front/rear more than 1.5 meters (5 feet).
    • Cannot interfere with vehicle maneuverability.
    • Securing to prevent unintended movement.

Overview of Loading/Unloading Procedures

  • Prioritize safety when loading/unloading containers.
  • Park on a level surface and use parking brakes.
  • Check the container and loading area thoroughly (damage, hazards, debris).
  • Communicate with dock workers.
  • Ensure proper lighting and use appropriate protective gear.
  • Secure cargo properly using appropriate tie-down methods.
  • Distribute weight evenly within the container.
  • Check for shifting cargo before closing the container doors.
  • Be aware of pedestrians and other vehicles in the area. Avoid pinch points when opening the doors.
  • Never leave the vehicle unattended during loading/unloading.
