These devices combine the power of compressed air with the precision of hydraulic systems to lift heavy loads. They utilize pneumatic pressure to drive a hydraulic pump, which in turn, delivers pressurized fluid to a cylinder. This fluid pressure then exerts force on a piston, generating the lifting power required for tasks like vehicle maintenance or industrial assembly. As an example, consider a mechanic using one to raise a car for tire replacement; the compressed air from a shop’s compressor powers the hydraulic system that elevates the vehicle.
The combination offers significant advantages. The use of air reduces the manual effort needed for operation, improving efficiency and minimizing operator fatigue. Their design also allows for precise control over the lifting and lowering process, crucial for safety and accuracy. Historically, these tools evolved from purely manual hydraulic jacks, incorporating air power to enhance speed and ease of use, becoming indispensable in automotive repair shops, construction sites, and manufacturing facilities where heavy lifting is a routine requirement.
