FAQ

The simple reason is that Hydraulics utilizes fluid as opposed to Pneumatics (air) although both are referred to as fluid power , the liquid normally oil used in hydraulics is simply uncompressible. SO THE FLUID is essentially stronger than STEEL when a pump pushes the oil to a device like a cylinder, imagine the fluid being a solid BAR of STEEL say 6 inches in diameter, it is literally like pushing a bar of steel. Heavy equipment say could normally operate at say 2500 PSI out of the pump, since the pump pressure is essetially regulated, it is simply a matter of selecting the desired force and sizing say the cylinder (for instance) appropriatey. Since: Force = Pressure (pump pressure) times Area (of the cylinder) The forces are absolutely staggering with a quarter of a million pounds force off a 10 cylinder at 2500 psi pump output. the chart below may not have been converted properly, but if you work the equations, you will see that the incompressibility of the fluid is the secret to limitless amounts of power. Usually safety is the only limiting concern with hydraulics as it is easy to die working close to anything with such reserve and speed.

what kind of engineers make sawmill machinery?

Mechanical engineers most likely I have 'made' machinery for different plants. Technically, I design machinery, other people make it. I am a mechanical engineer and I need the assistance of an industrial engineer and an electrical engineer.

Heavy machinery as in tractors... what would you need human labor and heavy machinery for in a horse farm

growing feed and hay -- horses eat a lot.

What are the five major cost components of the project cost?

Material cost means the amortization of the raw material, structural parts and semi-finished products, auxiliary materials, and turnover materials and the rental costs of the raw materials, components, fittings and semi-finished products, auxiliary materials, which are included in the budget. Mechanical use fees refer to the contents of the quota included in the budget, the mechanical use fees incurred in the construction process and the rental fees of the construction machinery leased by the outside units, and the fees for installation, disassembly and entry and exit

This book was published in 1927 by John Deere Corp., the first of a series for use in schools. It is now mainly of interest to collectors of antique farm machinery.

You want to buy a chip fab? How many millions/billions do you have?

wolframite is a tungsten ore

I could not locate machinery specific to wolframite or tungsten, so presume that they are mined the same way that other underground metals are. Equipment would include drills to make holes and break up rock and loaders to carry the rock away. You would also need support systems for tunnels and lights and safety equipment for the workers. Processing is done in a handful of places in the world--again I found only generalized descriptions of the process. The websites listed below are of some help.

I have never dealt internationally before and am a little leery about doing so. The seller looks legitimate but how can I be sure? Is there a way to check if there were problems with their machines, quality issues, etc?

Contact their nearest Embassy they will have a Trade Commissioner you can discuss it with. Contact your own Government somewhere you will have a Trade Department. Both these can do checks on your behalf for free. QUALITY 1: Ask for some references where they have sold their Machines etc, then check up on them. QUALITY 2: If you are dealing with Asia most don't know what quality is and will openly lie to you, especially China. Did you know over 50% of Chinese Toy manufacturers this year went out of business because of Quality problems? Believe me it is a problem in most of their manufacturing industries.
