I want to build some heavy-duty racks with four wheels each as follows. The load is not more than 500 kg. The frame is made of slotted angle iron and the board is about 8mm thick.
The available wheels are
What is the easiest way to attach the wheel? There are two kind of wheels here, with a bar that must be inserted to the frame or a flat base wheel.
Edit
I found from the internet:
What kind of base plate is it?
Best Answer
You'll use one of the variants with the plate on top, and you'll use three of the four slots for carriage bolts. The carriage bolts should have square lugs that fit the size of the slots.
If you find that the corner bolt doesn't have good bearing, or the hole wouldn't be well-positioned with respect to the ends of the metal components, you many need to first install corner plates of heavy steel (1/4" or better). These could be anchored to the bars with four bolts positioned outside the area occupied by the caster plates.
The variants with the pins would require metal bores to properly support them against that load. You'd have to bolt metal blocks into your frame. It's not a good strategy.
