Heavy vehicle load restraint

All heavy vehicles

A load restraint will meet the Load Restraint Guide standards if it doesn't shift when subjected to forces.

Load restraint forces diagram - described below

The load restraint system must be capable of withstanding these forces:  

  • 0.8 'g' deceleration in a forward direction (80% of its weight in forward direction)
  • 0.5 'g' deceleration in a rearward direction (50% of its weight in rearward direction)
  • 0.5 'g' deceleration in a lateral direction (50% of its weight in a sideways direction)
  • 0.2 'g' acceleration relative to the load in a vertical direction (20% of its weight in a vertical direction)

'G' (the acceleration due to gravity) is taken as 9.81 metres per sec per sec (9.81m/s squared).
