Fluid Power Project: Hydraulics

Fluid Power Project: Hydraulics -Maccoy Merrell and Zachary Stinson What are Hydraulics? Hydraulics are systems that transfer energy/work through water or other aqueous substances. Some examples of these systems are convertible cars, Levis project, and drawbridges. Why Hydraulics?

Hydraulics provide many advantages over pneumatics, such as Adjustable extension length Superior extending power Cheaper Easier to perform maintenance on Scissor Lifts Our Design Scissor lifts are an ingenious contraption that allows upward mobility when providing a horizontal force. It is composed of two simple machines, the lever and the axle.

Axle Lever PROBLEMS:

Sealing system Scissor Lift Friction Scissor Lift weight Scissor Lift Mounting Clamps Levis Presentation Why ? While scissor lifts are an ingenious design, they are a

severe pain to mount. This is due to the fact that every piece of the scissor lift must move in order to function, so it cant be simply mounted. Other than that, many moving parts adds mass and friction to the design Calculations Our Design Weight: 1.25 lbs Area: 1.1625 Inches
