design of mechanically operated bottle jack pdf

Jack is a mechanical device used as a hoist for lifting heavy loads or apply great forces. mechanical Jack use a screw thread for lifting heavy equipment. the most common form is Jack, floor Jack or garage Jack which lifts vehicles so that maintenance can be performed. Mechanical jacks are usually designed for maximum load capacity (for example, 1.5 tons or 3 tons). More powerful jacks use hydraulic power to provide more lift at great distances and can be evaluated for many tons of cargo.

voice operated intelligent lift or elevator

Abstract

The main aim of this project is to design and construct a voice operated lift/elevator control system. This system acts as human-machine communication system. Speech recognition is the process of recognizing the spoken words to take the necessary actions accordingly. User can also control the electrical devices like fan, door etc with the help of voice recognition system. This device is very helpful for paralysis, short height people and physically challenged persons. The speech recognitio ....etc

voice operated intelligent lift or elevator circuit diagram

Now-a-days we can find huge no of apartments crowded in nearby area with multi storage building capacity. The apartment consist of several floors. This project better suits for all, mainly for physically challenged people. To move from one floor to another we generally used staircase or lift which is normally operated by using switches. The main purpose of this project is to operate the lift by using voice command.

The speech recognition system provides the communication mechanism be ....etc

This device continuously auto lifting and lowering of a hydraulic jack that can run automatically and continuously lifting and lowering cycles without some external force. (a) the hydraulic circuit is simplified due to the location of the control valves to achieve reliable and convenient control.

Hydraulic jack uses a liquid which is incompressible, that is forced into the cylinder with the piston pump. Oil can be used as a lubricating and stable. the fuel comes from the tank through the suction check valve in the ....etc

ABSTRACT

The conventional method of using rope, ladder, scaffold and even mechanical scissors lift in getting to a height encounter a lot of limitation (time and energy consumption, comfortability, amount of load that can be carried etc), which hydraulic scissors lift is set out to achieve. In this project a mobile scissors lift has been designed that will be powered by hydraulic to a height of 3m carrying a maximum load of 300kg. the project has been tested and it work successfully.
