Remember the 10/10/20 Rule When Hauling
Proper payload management is not only important to the health of your equipment, but to the health and safety of your employees. That’s why it is important to understand the 10/10/20 rule—and to follow it.
The rule states, “No more than 10 percent of payloads may exceed 1.1 times the truck’s target payload and no single payload shall ever exceed 1.2 times the maximum target payload.”
Another way to look at it is that no more than 10 percent of loads may exceed 10 percent over target payload and no loads may exceed 20 percent over target payload.
- The 20 percent “never to exceed” is for the safety of the operator. When you exceed target payload plus 20 percent you have exceeded the steering and braking certification of the truck.
- Loads in excess of 20 percent over should be dumped at the face.
- The mean (average) of the payload distribution shall not exceed the target payload.
