What does Hauler's 500 lbs rating actually mean?Updated 2 hours ago

It's what the structure (frame, axles, wheels and bearings) will carry—measured on hard, level ground. It isn't a promise that 500 lbs is manageable everywhere. Three things change what you can actually move, none of which change the number on the scale:

Where the weight sits: a load stacked three bins high could lean or tip on a turn or curb at a weight that would otherwise stay planted on the floor.

What you're rolling on: sand, mud, deep grass and gravel can make the wheels plow instead of roll, and soft ground under one wheel can tilt the whole load.

Grade: uphill multiplies the effort, downhill turns the load into something you have to hold back and a side slope pushes the weight onto the downhill wheels—the single most common way a loaded Hauler can go over.

The practical limit is whichever comes first: the 500 lbs structural capacity, or the load you can start, steer and stop on the ground you're actually on. On soft or sloped ground, the second one is almost always lower.
