Hi Brian,
Well, not sure where to start. I guess I'll start with specs. Specs vary from manufacturer to manufacturer and within a manufacturer. As good as Bobcat is and anybody for that matter, you can find two different figures on most specs related to hydraulic lift capacities, breakout forces, hydraulic horsepower ect...
One of the reasons for the discrepencies (sp?) is that when machines are being developed and engineered most manufacturers start with theoretical statistics. Such as, a cylinder of x diameter with a stroke of y @ 3200psi x 12 gpm should = X.
Some manufacturers don't even physically measure those calculations to see if they are correct. Hence you have a estimated #. Later, after development, our machines get physically measured by SAE standards. ( 500 mm from pin) for breakout for example. You may end up with two different figures. Society of automotive engineers SAE doesn't provide criteria measuring all the pressures and capacities, this leaves room for manufactures to manipulate the numbers.
There also are some tricks that some manufacturers use to askew the numbers. An example would be Kubota's bucket breakout on their excavators. They have 2 pin locations, one for loading a truck and one for digging. Guess what, they look great on paper, but I don't know anyone who is going to get out, and hammer out 2 pins to switch the positions after every dig cycle.
They also rate their forces at a "place and time" through the lift cycle. So at this spot right here ( 142"s boom out, crowd at 42 degrees, bucket at 30 degrees) we get "x" amount of force...so that's what they publish. Bobcat, you will find, uses a average of the digging cycle...it's a more accurate, real world rating.
Horse power is another one. For decades, Bobcat listed horsepower based on " net", where as everyone else used gross. The competition looked stronger because it was not apples to apples. Net horsepower is based on a engine laden with a muffler, alternator ect.....a truer rating---not a bare engine sitting on a dyno.
With todays web capabilities so many people shop Specs to narrow down what their even going to look at. I have great products to sell, that either compete or more than not, out perform the competition. But I may not even get a sniff because a guy didn't like spec "y".
Let me tell ALL OF YOU!......DON'T SHOP SPECS!!! Go to your dealer and demo the units.
The proof is in the pudding.
Our skid loaders spin our hydraulic and hydrostatic pumps side ways with a pulley.....guess what? Our 773 bobcat at 46 horse had more hydraulic horsepower, more axle torque, and would out lift a 56 horsepower case 1845!
DON'T SHOP SPECS.
Hey Brian,
How about I bring a tractor out and we lift your pallet. Your loader is probably going to be in late next week but we can do it with another one I have. I'm not saying it's going to do it, but let's try it, it's the only way to know for sure.
I hope I haven't come across confrontational, for that's not my intent, if I accomplish anything with this post I hope it is to encourage anyone looking to purchase anything......go try it....don't "bench race".
