Pneumatic jacks

 

— in such jacks, the rise is carried out due to the pressure of air or other gas that fills the working chamber. The main advantages of pneumatics are high speed and convenience for the user (no need to exert physical effort). However, a source of compressed air is required for operation (it can be a compressor, an exhaust pipe of a car, etc.), and pneumatics are not designed for long-term retention of a load — it is recommended to use stands for this.
