Pneumatic vs Hydraulic lift?

60 years old RCC building has ground floor plus 3 floors plus terrace. There is constraint of space, not possible to dig a deep pit, nor space for specific room for the lift and accessories. Major changes to the building structure will not be allowed. Each floor is 12 feet high. At least 3 people each weighing 70 kg and may be 6 feet tall  should be using the lift at a time. Capital cost wise and operating cost wise which from pneumatic or hydraulic suits the conditions?

    This is a professional level problem for a novice.   What you need to do is get good information without being persuaded by a supplier salesman who will give you bad advice (sell you the wrong product).  That is where knowledge and experience becomes valuable.  What you need to do is look at other buildings and elevators that have a solution to what you think your problem is.  Then get the information/opinion about their elevators.  Talk to the managers of those buildings.  Do it enough and you will begin to find consistent names, products, opinions, mistakes, etc.  And improvements to the most recent concepts.  At that point you are ready to talk to the vendor/suppliers.  You call them in and give them the problem and ask them for their solution.  In the meantime, you work on what you have to change to make what they are doing fit.  From that you should have the preliminary plan for your project.

    The link below gives you some information for the various small elevator systems. Your question seemed to be worked as a home work task. I believe you can get a good idea of the various choices and cost from the link below

    Are you asking whether or not you should use and pneumatic or hydraulic actuator for an elevator? Elevator systems are extremely expensive and you should get a qualified firm to design a system. While there are pneumatic and hydraulic lift options, there are also cable lift and mechanical options available.
