RK Tractor FEL Lift Capacity Vs. FEL Bucket Volume

   / RK Tractor FEL Lift Capacity Vs. FEL Bucket Volume #31  
IOW, the maximum amount of water it can carry (?).

For practical purposes yes, but not technically in all cases.


To explain...
For the case of a bucket shaped as shown on the left, you would be correct.
But for the case of a bucket shaped as shown on the right, it could be said that the true volume of the bucket was blue+green, or even some of the white area as well if it was sand struck-off, yet the blue is the most water it could carry.

Again though, practically speaking, the volume any operator cares about would be the blue area.

Volume is a mathematical calculation and a legal term.

Think about it with cooking. A tablespoon is a tablespoon. They are measured "level". Regardless if that level measure is liquid (like water, eggs or oil), fat (like butter or shortening) or dry (like flour, sugar or salt) - it is all a "tablespoon".

Can you heap liquid? No. Can you heap flour? Yes - However, it is only a tablespoon if it is level. How would it be if, when you went to the store to buy a measuring spoon, the maker of the spoon labeled it according to how high someone might heap flour while another labeled it as to how it heaps sugar (which won't heap as high as flour) ... would people trust the measuring spoons? No real cook/chef would. They want the "level" measure.

The same holds true of a FEL bucket. It is rated as to "level" full. Not how high someone can heap various loads. For one, not all goods can be heaped the same. Secondly, it would be illegal to list the capacity above what is a level measure.

So, FEL, backhoe and excavator buckets are rated for the actual volume of a level measure as calculated by the mathematical formula for volume.

How high of whatever you want to heap it is up to you - for the measure of the buckets to trusted and legal, they must be rated for level volume ... it is that simple.

I demoed a rk55, the bucket has considerably less usable capacity versus my Ford 1920 that has 14cu.

TYM states 11.2 cu ft. TYM 70 hp machine has a 13.8 cu ft bucket. I don’t think my 1920 bucket is that big.

Crushed stone is a good benchmark for material weight. It’s 100lbs per cubic foot average. So filling any of those buckets would be under the lift capacity- but- where was that capacity measured? Typically at the buck pins, which is useless. You want to look at the rating 500mm out, or about the center of the bucket.
I confess that I did not look where the RK loaders were rated.

As I read through all these posts it was hilarious at first, and then a little sad.
