Forklift which powered by aircompressor

  Pneumatic systems are rather expensive, and that is mostly due to the cost of the compressor (or so i heard).
  
  You can still make a forklift working on a pneumatic circuit. but it has its own severe disadvantages.
  
  with pneumatic systems, there will not be any level control. the working states of the system will be either "on" or "off'.
  
  which means that , when you activate the direction control valve, the fork will rise in an instant, and when you shut off the valve, the fork will drop, as free fall. and in such cases if the fork is loaded, then some mishaps might take place.
  
  But if you were to use a hydraulic system, you can control the speed of the fork travel, and also lock the fork , at any point between its dead centres.

  u means its not possile....i accept that Pneumatic systems is not accurate than hydraulic but Pneumatic systems is cheaper than the hyadraulic...maintains cost is law..easy to servicing...no problem for oil leakegeing..etc..etc...

  Since I'm skeptical, I would start by researching the energy questions:
  

  • How much energy can be stored per unit volume in compressed air?
  • What's the maximum practical size for on-board compressed air tanks?
  • How much energy do conventional forklifts use per hour of normal use?

  With that information you can calculate how long the forklift can operate between refills.
  I don't know, but I suspect you'll have to refill the tanks a lot more often than gas tanks.
  And refilling high pressure air tanks isn't quick.
  And a lot of energy is wasted as heat when refilling.
  And high pressure air tanks are dangerous.
  
  But it does look like an interesting project that could possibly have applications in extreme circumstances.

  Pneumatic systems may be cheaper, but when an accident takes place, then you can imagine the price that one would have to pay.
  
  safety is a prime concern.
  
  Now when the weight of the systems, comes into question, then i say that it wouldn't make such a big difference, because the weight of the pump (in hydraulics), would be equal to the weight of the air compressor (in pneumatics).

  yes u can. I have worked on a similar stuff but din end well. Use Pascal's law properly and u can make wonders 😀
