5.3 – Checklist – Use a restraint system that is suitable for your load

The third step on the planning checklist is to choose the restraint method that is most suitable given your load and vehicle.

Loads can be restrained by two basic methods: tie-down or direct restraint (i.e. containing, blocking and attaching).

The following diagram shows the different restraint methods for controlling load movement in the forward direction. The same principles apply to backward and sideways movement.

It is possible and sometimes necessary to use a combination of tie down and direct restraint methods to meet the loading performance standards. For example, in some circumstances the tie down method may be adequate to meet the standards for lateral and rearward forces but may need to be supplemented with direct restraint to meet the forward movement standard (eg blocking using a suitably rated headboard) (see Lessons 4.1, 4.2, and 4.3)

In summary

  • Make sure you are using enough lashings of sufficient capacity if using the tie-down restraint method. (see the tie down checklist on page 26 of the load restraint guide)
  • Use a direct restraint method for loads that are difficult to tie down.
  • Using direct lashings to attach a load is especially suitable where there is little or no friction between the load and the loading deck.
  • Make sure you are using load-rated headboards and load rated side/tail gates if using the blocking restraint method.
  • Make sure contained loads can’t shift within the vehicle structure.
  • Make sure the load restraint method you use meets the Performance Standards.
