MECHANICAL LIFT.

Lift is a simple mechanical device used to raise elements or mechanical lift objects from ground level to a certain height to perform a specific work with maximum load and minimum efforts. This project describes the design as well as analysis of a mechanical scissor lift which works on the principle of screw jack.

INTRODUCTION;-
Nowadays, on heavy traffic roads or highways, if there is any technical problem in a car there are traffic issues. To avoid traffic problems, we need a mechanism that can lift the car at a particular height and move it aside on the road. So our purpose is to create a mechanism that is operated mechanically by using manual power. Nowadays there is a hydraulic brake and pneumatic lift but in accidental cases or any technical problem.

It is difficult to carry these systems as they are bulky and also need a lot of maintenance but this mechanism is portable and requires less maintenance as compared to pneumatic and hydraulic systems. Nowadays as every mechanism is getting optimized related to space and portability our aim is to optimize and make a portable lift that is easily accessible and easy to use. The aim is to lift a certain car with a portable mechanically operated lift to do certain work like oil change, underbody jobs, car wash, etc.

DIFFERENT TYPE OF MECHANICAL LIFTING MACHINE

With the headway of innovation and technology, there are various lift machines which can be effectively gotten to in the market. Time was when individuals used to lift up a substantial object with their hands. The present age has made the assignment very simple for all. In the cutting edge age, the lifting machine takes every necessary step of carrying an object with substantial weight which makes the task of lifting less demanding for workers.

• Forklifts
  The forklift is otherwise called a fork truck. It is utilized to move things in a short distance with the assistance of two metal bulges that are settled at the front piece of the equipment. The forklift can be effectively moved in the encompassing zone of a distribution center. The front end segment of a forklift is sufficiently potential to lift up any tall things with ease. There have even been instances of forklifts lifting autos. However, to operate a forklift one needs to be trained and expert at it.
• Winch
  The winch is considered as a lift machine for heavy objects and can be utilized to tow a vehicle. In the event that your truck stalls out in muck or mud, you can move your vehicle effectively with the assistance of a winch. A winch is utilized to change the weight of a wire link while towing a vehicle. There are various sorts of winches in the market.
• Crane or Hoists
  All in all, it can be said that lift machines make it very easy to move a heavy object from one place to another. It not only makes the task easier but also saves a great deal of time. With the right equipment, you can get more than expected results and bring in more efficiency for your business. Do you also use lift machines in your facility?

USE OF MECHANICAL LIFT

When a patient is not able to bear weight on his or her feet, a mechanical lift should be used. A mechanical lift takes the strain out of lifting and drastically reduces the risk of injury. While using any mechanical device it is important to communicate with the patient to keep him or her calm. Make sure to use the proper sling and adjust the straps to fit the patient properly.

ADVANTAGES OF MECHANICAL LIFT

1. Low Cost.
2. No Oil Leak.
3. Longevity Life.
4. Accurate Positioning.
5. No natural falling.
6. Easy maintenance.

CONCLUSION;-
Instead of using hydraulic or pneumatic lift we have used mechanically operated lift which is more cost-efficient and portable. We have designed scissor lift in such a way that it has reduced design complexities. All the design calculations are performed taking into consideration the dimensions of the car and all the safety issues. Modifications can be done by providing rollers to the lower base so it could be portable. Also by providing upper magnetic base ferrous material can be held easily.
