Stupid castor question

Here's how to get your castor weight requirement for a give table plus its
load:

Equipment weight + load / 3

Example: your table weights 50 pounds and will hold 100 pounds of stuff:

50 + 100 / 3 = 50 lb rating per castor.

Solution: Buy four castors rated at 50 lbs each

NOTE: Use three as a factor, even if you are using four castors.

Yup, and mum would line all five of us up, grab one nose at a time, and
shove a spoonfull into each little gagging mouth. Was the olden days

Sounds more like what we'd call a "kitchen cart". You're right about locking
casters.

authoritative answser: "It depends".

On who is talking.

Some people publish load capacities for a -set- of four. Particularly
when they are selling them *in*sets*of*four*.

More responsible parties publish the load a _single_ caster will handle.

Read the fine print. If still in doubt, *ask* the seller.

Yes really ... note I stated "high quality" casters to begin with and said
nothing about cost. Equating cost with quality can bite you, as you've found
out.

Absolutely nothing "invalid" about it ... it is an industry standard formula
for figuring weight ratings for equipment on _four casters_. How many
butcher block kitchen islands have you seen with less than four casters?

Forget weight ratings. The light ones will carry the load. What you want
is a good caster that will swivel and roll easily. Don't scrimp on the
wheels or you will forever curse the fact that you saved $3 on the project.
Big wheels are better than small ones in most cases.

I have one with less than four casters.

It has *zero* casters.

So there! :P

You could also make do with three if you have a couple of spare cats laying
around. Just stick one under the high leg.

On a roll-around, butcher block kitchen island, which is what the OP is
building, you certainly want to take caster weight rating into account. If
they're high quality and rated correctly, the swivel and roll ability will
take care of itself.

agreed Swingman, lifting gear slings chains cables are factored by 3 even
with 4 lifting points.

one thing to consider is how smooth and level a floor it woll be on
and how much rolling around it will do. if you have a very lumpy floor
such as saltillo tile or slate the tires will tent to catch while
rolling. when this happens, all of the weight effectively is taken by
one wheel.

Not really. A high weight rating means nothing to the quality of the
bearings or the swivel. I buy casters at work. Some that I buy are $75
each. There is some real crap with high weight ratings.
They may not crumble, but they don't move well either.

Best one I've seen just had two - you tipped it up a bit like a sack

You're a gub'ment worker aren't you?

UA100

This calculation may be invalid if you only use 2 casters, as it seems the
assumption for it is 3 or more.
