Air Compressor: It is used to compress the air for useb. Pneumatic Cylinder: Uses compressed air and converts it into linear force. Pressure sensor: It is used to measure the air pressure in the system. Pressure regulator: cuts off the air supply at a certain pressure. Vacuum pump: It is used to create vacuum. Similar to the hydraulic lifting mechanism, it also consists of a cylinder and piston arrangement. The difference is only that it uses air as the pressurization medium instead of hydraulic fluid. But the pneumatic mechanism cannot bear the same load as hydraulic lifter due to the compressibility of air. But besides this, it provides clean operation and is used in food processing units, medical industries, etc. 3.) The mechanical hand lift uses manual power to lift the load. This type of lifts is operated with the strength of the hand or foot and uses mechanical parts such as gears, chains, cogwheels. This mechanism uses various mechanical components such as screws, gears, chains etc. To lift weight or load.4.)
