2. INTRODUCTION
Our project is related to the part of the human safety. Due to multinational collaboration of
domestic companies with foreign countries mear about 40% such organization have their
production facilities in india. Hence after globalization many clauses regarding factory act have
been changed by the government of india, Ministry of human resource department &Company &
labour act 1957. For all such companies domestic as well as multinational these rules &
regulation are same in the organization having rotating & moving machineries the employee
safety is given a first reference. As per the Japanese concepts- under ISO & procedure & clauses
there are different kaizens about employee training & safety.
We are concentrating out of one very important clauses it to maintain the operating,
working and movement height of the person inside & outside the company campus. So no
employee can work over 8 feet height measuring from the shop floor. Or if any material has to
move more than 8 feet height no employee is allowed to move it manually. Not to allowing to
do so, because of the certain person health related issues.
1) For example _if any material has to move upward 10 feet overhead from the person
working station &cycle time for each part movement is 5 sec & suppose 300 parts has to
move in shift of 8 hours. The operator has to suffer for the fatigue stress & strain on his
arm of hand he will be injured.
2) While working in the construction companies for overhead beam joining, Fabrication and
painting, person has to attain that much height , so for safety working condition to that
much height the lift can used.
3) MSEB Electricity pole work –The wiremen or the electric technician has to go to top of
the pole for fault finding & repairing work. Without safety it is highly risky &chances to
fall down ,electricity shocks could be the reason of the employee death till the equipment
have been developed but that are to costly & bulky. Hence to avoid these limitation of
working at height more than permitted & to send the material at height more than
permission, we are developing the cheapest product or the system pneumatic lift.

3. WORKING AND CONSTRUCTION
Cranes can be classified according to working principle into three types,
a. Mechanical lift
b. Hydraulic lift
c. Pneumatic lift
A:Mechanical lift :
In this ropes chains belts & an electric motor are used to lift the objects
B: Hydraulic lift :
This Type of equipment consists of an electric motor or internal combustion engine or
hydraulic pack to drive a pump which feeds fluids into a hydraulic operating cylinder through
the lines with control valves. It provides for speed control over a wise range. Ensures smooth
operation of the mechanism without impacts. Employs simple means of protection against
overloads & is compact Consequently the hydraulic drive enjoys ever increasing popularity
in hoisting installation, especially traveling cranes unfortunately high cost of certain
constituent components limits the application of the hydraulic drive on a large scale.
C: Pneumatic lift :
Here compressed air is admitted into the direct acting power cylinders under pressure. The piston
rods of the cylinders are linked with the business end it displays low efficiency in handling light
loads & limits the radius of action of movable machines by the length of the air hose.
The pneumatic lift means air operated machine or mechanism. Which is used for lift the load. It
consist the link and sliding bush type mechanism. The cylinder used for operate the link in
upward and downward direction. The pins are used to join the link which are move over the pin.
