DPK32rail layer is composed by host machine (Cart No.1), Cart No.2 and flip gantry.The parallel operation order is: host machine lays the track, Cart No.2transports, and the flip gantry lifts and loads. This means: the track paneltrain enters, the flip gantry lifts the track panel, and loads them to cartNo.2, the cart No.2 transports the track panel to the rear end of host machine,the dragging winch drags track panel to the host machine and returns theguiding-rail to cart No.2. The cart No.2 returns to the flip gantry with noload, meanwhile, the host machine starts laying track.

Whilelaying track, the machine arm rises from transporting state to working state,the crown block operates, in order to alignment the rail hanging pole with thetrack panel to be laid. Rail hanging pole lands, the automatic coupler couplesthe track panel, and then the pole rises, raising the track panel 20cm.  Crown block moves forward, and the hostmachine also moves forward. When the track panel separates from host machine, thepole starts to land, after locating well with laid track, the track panel landson the roadbed. The host machine moves forward along the newly-laid track,meanwhile, the crown block returns, to lift another group of track panel,finishing a working cycle, repeating the above procedure. While laying curverail, use the arm swinging mechanism to swing the front part of arm, finishingthe job.

Q:The machinery will be depreciated over ten years using the double-declining balance method. If depreciation is computed on the basis of the nearest full month, Foley should record depreciation expense for 2007 on this machinery of $20,800. $20,400. $20,550. $20,933.
Assume the machine useful life is 10 years Double-declining-balance method Rate: Double of straight-line rate 100%/10=10% x 2 =20% Depreciation Expense: Year 2006: $120,000 x 20% =$24,000 (whole year) $24,000/12=$2,000 (every month) There are only 8 months (May-Dec.) $2,000 x 8 = $16,000 Year 2007: ($120,000-16,000) x 20% = $20,800 Unlike the other depreciation methods, salvage value is ignored in determining the amount to which the declining balance rate is applied. Depreciationn stops when the asset's book value equals expected salvage value.
Q:Okay, so I'm looking through my bio textbook (not ap) and I come across this graphic about the HIV virus. There's a strip of text that talks about how the virus replicates itself:HIV is equipped with the enzyme reverse transcriptase.........Using the cell's **gene translation machinery**, this DNA then directs the production of thousands of viruses.The thing inside the **s . What is it? Cells don't have machinery! Why does the book call it translation machinery?
It's talking about the complement of proteins used to copy the DNA and produce new viruses that are hijacked by the virus. Proteins are like little machines. They're the molecules that do everything in the cell.
Q:nan
You will find quite a bit on OKorder if you look under business equipment. Unbelievable listings.
Q:I was tasked to look for at least two design experiments to illustrate the industrial applications of AC machines. We are going to perform the design experiments in our laboratory classes. Please help me. Anything simple could do.
You could demonstrate that as the load on a three phase induction motor or transformer, increases, so too does the power factor. This is something that is important to demonstrate as it will lead to the correct size motor or transformer, being installed. A second demonstration could be showing that as the mechanical load on a three phase motor, increases, the motor draws more current and the slip speed percentage, increases slightly. You can use a prony brake to apply more load in both of these demonstrations. You will also need a power factor meter, a watt-meter and a tachometer.
Q:could anyone provide me with a diagram please .
This is entirely product dependent. Some products must be harvested quickly and then processed in some way or the quality will start to deteriorate as soon as it is disconnected from its life support system. This would include things like green beans or other vegetables that are to be frozen or canned as close to the harvest location as possible. Other items have an inverse relationship to the speed as far as final quality is concerned, and in some cases within the limits of the harvesting machine, it makes no difference. You need to be more specific to get a good answer to this question. I would also have to make an assumption that this is a harvesting machine, not a soil prep or planting machine.
Q:nan
a lot more than anyone would admit ...
Q:nan
To help reduce undesired oscillations/vibrations or slow down the effect of a moving piece. Examples: 1) In automobile shocks to reduce bouncing after going over a bump 2) On a door to allow it to close but stop it from slamming shut 3) On fixed structures such as bridges to dampen down natural oscillations as a result of environmental forces such as the wind.
Q:I have to explain how something works but my mind is blank! I have absolutely no ideas! So what is a technologocial machinery that is simple to explain in 3 minutes or less? My teacher mentioned a remote control, but that's a little too hard for me. Do you have any ideas?
Try something without moving parts and electricity, like a pencil or pen for instance.
Q:have trouble doing anything as i injured my right hand an i'm right handed and live alone.
I don't understand why you would ask such a question here in yahoo. This requires an attorney who is familiar with liability law, the facts of the event, and what the history is of that company relative to accidents.
Q:please hurry school project due TODAY
Big giant coal burning factories with smoke stacks.
