How Do Pneumatic Lifting Mechanisms Differ from Hydraulic Lifting Mechanisms?

Posted by Alan Wood on January 18th, 2021

Lifting Mechanisms make use of various actuating mechanisms and components – to offer the upward pushing force that is needed for hoisting an object, and lifting and material handling.  Pneumatic, Hydraulic and Mechanical happen to be the three main types of actuators that are integrated into the designs of lifts. Of these, the first two types, Pneumatic and Hydraulic lifts, work as the commonest systems to be used. Find out how one varies from the other.

Pneumatic Lifts

These use a lifting system comprising of a piston and a hollow cylinder. The piston is moved inside the cylinder by an external pump or motor. It raises the air pressure inside and makes the cylinder move along the piston axis. The movement of the cylinder along the axis generates a linear force that is used then for extending the components of the lift and lowering or raising an object.

Collective versatility is the benefit of using pneumatic lifts. Lots of pneumatic lift models need no electrical power for operations, and may be used in varied platform for lift installation settings, such as areas that are susceptible to explosions and places with extreme temperatures.

Hydraulic Lifts

This kind of lifting equipment uses a lifting system like the one in pneumatic lifts. However, rather than compressing air, hydraulic oil or a similar liquid is compressed by the hydraulic mechanism for raising the internal pressure inside the cylinder. The actuating cylinder’s linear motion results from a rise in internal pressure.

It can produce as much as or more than 25 times the force that is produced by pneumatic lifting mechanisms of comparable form.
