When you're loaded to the point where your weight will exceed your legal weight as a tandem truck. Honestly, you should probably have it lowered any time you're loaded, since a motor carrier officer who sees a tri axle, quad axle, etc. with a raised lift axle is likely to question it... even if you are legal, it's time wasted and another annoyance to deal with.
If you mean when after you get loaded, you do it while the vehicle is not in motion - don't lower your lift axle while the vehicle is moving.

How do you convert tandem loads to triaxle loads?
To convert tandem loads to triaxle loads, you need to assess the total weight supported by the tandem axles and then distribute that weight across the three axles of the triaxle configuration. Generally, a triaxle can support more weight due to its additional axle, allowing for better weight distribution and reduced stress on each axle. You may also need to refer to specific load distribution guidelines or regulations applicable to your region, as they can vary. Overall, the conversion involves ensuring that the total load does not exceed the legal limits for triaxles.
What is a tri-axle dump truck?
It's a dump truck with four axles--the steer axle in front and three axles in back. One of them moves up and down via a control in the cab, so the tires aren't on the road if the truck's not loaded. A tri-axle dump truck carries more weight than a one-axle or two-axle truck.
