Hydraulic Jack, Automatic 12 volt DC - College Project

Click For Summary

Discussion Overview

The discussion revolves around a final year engineering project involving a 12 volt DC hydraulic jack designed to lift light motor vehicles and light commercial vehicles. Participants explore the design, functionality, and technical aspects of the jack, including its components and potential improvements.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant describes the hydraulic jack's components, including a 12 volt DC motor and hydraulic pump, and its intended use in vehicles and service stations.
  • Another participant expresses admiration for the project and inquires whether the electrical parts were assembled from scratch.
  • A clarification is provided regarding the term "scratch," comparing it to cooking from basic ingredients rather than using pre-made components.
  • Concerns are raised about grounding the motor to the vehicle body, suggesting that finding a conductive area may be challenging due to plastic parts and paint.
  • Another participant counters that grounding is not difficult if the motor terminals are adjusted, although this response is met with skepticism regarding its clarity.
  • A participant confirms that the person operating the switch in the video is a classmate, while they themselves are present for a viva examination.

Areas of Agreement / Disagreement

Participants express differing views on the practicality of grounding the motor to the vehicle body, with some suggesting alternative methods. The discussion remains unresolved regarding the best approach to grounding.

Contextual Notes

There are unresolved technical details regarding the grounding method and the implications of changing motor terminal connections, which may affect the project's implementation.

Hello Frnds,

I am presenting my engineering final year project. It is a 12 volt DC hydraulic jack. This jack is made to lift light motor vehicles and light commercial vehicles. Its capacity can be increased by changing some parameters. The project consists of a 12 volt DC motor, a hydraulic pump, a control unit and other parts . The idea beyond the project is to replace conventional jack used in the vehicles with an automatic jack in order to reduce the physical effort required to lift the vehicle. The jack was made in 8th semester by me and working fine.





This jack is useful in vehicles as well as in service stations. Installing this jack in a vehicles is better idea to reduce the last effort of putting the jack at right place for operation. Still I am working on the design for making it compact, light, & more useful in modern vehicles.

that's very cool, I wish I was doing something that cool for my final project sniff.

Did you guys put together all electrical parts from scratch as well?
 
What do you mean by scratch ?

"Scratch" means from the ground up, without pre-made parts. The term originated in the field of cooking. It's like when you make a cake using flour, baking powder, etc. rather than a boxed mix.
That is indeed a cool project. I have only one concern, which I think might just be a matter of terminology. You're pretty specific about grounding the motor to the vehicle body. That's pretty optimistic. What with plastic parts, paint, undercoating and whatnot, it's increasing difficult to find a conductive area on a car. Even in my very old vehicles, I usually have to hook onto a suspension piece or engine bracket. It might be more practical to use twinned wire (like jumper cables) and just ground to the alternator mount in all cases. It would be heavier, but maybe worth it to avoid hassles. Just a thought.

No dear, grounding is not so difficult. Just only you need to change the terminals inside the motor. Brush connected to negative and positive are interchanged. Means You need to change the polarity inside the motor.
 
The video is pretty cool. Is that you working the switch?

I hope that you realize that the foregoing quote makes absolutely no sense whatsoever.
 
Thanks. No, that's not me working the switch. He is my friend (classmate) Abhishek Jain. I am facing the viva standing sideways with our HOD. Yes but the person dropping the jack is me.
