This Angle-Iron Track Pulley is highly useful ⚙️

Great idea

Did you know that in the past, curtain rods had metal rollers with wheels that moved like a train?

El rodamiento a bolillas que se muestra no es para esas cargas

If the supporting frame were rotated 90 degrees, it would withstand much more weight and be safer in the event of damage or excess weight.

It would be safest to connect the upper part, which is near the wheels, to each other.

Great idea 💡

But . But there's weight limit...

Уголок в таком положении согнётся

Yes. It self-centers a load. 👍
