1. Are the loading performance standards designed for an accident?
The Performance Standards are designed to restrain a load during normal driving, emergency braking, and minor collisions. Crashes above this will result in forces above those in the Performance Standards.
2. Does a load restraint system need to hold the load if the truck rolls over?
No. Restraint systems are designed for forces experienced under normal driving conditions, like braking, bumps, and vibration. Forces on the vehicle involved in a roll over are far greater that what load restraint systems are required to withstand.
3. Can a 2.5t webbing strap restrain a 2.5t load?
Generally, no. The rated capacity of a strap indicates its maximum strength under straight-line pull, i.e. Direct Restraint, not its ability to restrain the same amount of weight. In Tie-Down restraint, blocking, friction, and pre-tension all effect how many webbing straps are required.
