With such a wide range of strength and length in commercial tie downs, it’s important to determine the aggregate working load limit of the equipment you choose before you attempt to haul your cargo.
What does aggregate working load limit mean?
Working load limits determine how much weight or force tiedowns and other securing devices can secure without breaking. The aggregate working load limit is the sum of the working load limits for each device you use to secure your load.
To meet safety requirements, the aggregate working load limit of the devices you use must be at least 50% of the total weight of all the pieces of cargo you are hauling.
How do you determine aggregate working load limits?You can figure out the aggregate working load limit of your securing devices by adding together:
- 50% of the working load limit of each tiedown that is attached to an anchor point on your vehicle, and
- 50% of the working load limit of each tiedown that is attached to your vehicle and goes over, around or through your cargo.
