Driver's Handbook on Cargo Securement - Chapter 12: Roll-On/Roll-Off and Hook Containers

What Does This Section Cover?

The requirements in this section apply to the transportation of roll-on/roll-off and hook-lift containers.

Generally, roll-on/roll-off and hook-lift containers are carried on specially designed vehicles that are equipped with securing devices on the vehicle. When the container is secured, it combines the container and the vehicle into one unit.

Securing Roll-On/Roll-Off and Hook-Lift Containers

This section deals with how to transport a container on a vehicle that is not equipped with a compatible and functioning "Integral Securement System."

Requirements for securing containers on a vehicle without an Integral Securement System

Block against forward movement by the lifting device, stops, a combination of both, or another suitable restraint mechanism.

Secure to the front of the vehicle by the lifting device or another suitable restraint to prevent side-to-side and vertical movement.

Secure to the rear of the vehicle with at least one of the following three mechanisms:
  • Rear Mechanism 1:

    One tie-down attached to both the vehicle chassis and the container chassis.

  • Rear Mechanism 2:

    Two tie-downs installed lengthwise, each securing one side of the container to one of the vehicle's side rails.

  • Rear Mechanism 3:

    Two hooks, or an equivalent mechanism, securing both sides of the container to the vehicle chassis at least as effectively as the tie-downs in the two previous items.

Attach mechanisms used to secure the rear end of a roll-on/roll-off or hook lift container no more than two meters (6.5 feet) from the rear of the container.

[Note:] Each mechanism must have a WLL of at least 2,268 kg (5,000 lb.).

Manually install additional tie-downs if one or more of the front stops or lifting devices is:

  • Missing
  • Damaged
  • Not compatible

Manually installed tie-downs must provide the same level of securement as the missing, damaged, or incompatible components.
