3. Jackscrew - Wikipedia

   en.wikipedia.org/wiki/Jackscrew

   The maximum mechanical advantage possible for a hydraulic jack is not limited by the limitations on screw jacks and can be far greater. After World War II, improvements to the grinding of hydraulic rams and the use of O ring seals reduced the price of low-cost hydraulic jacks and they became widespread for use with domestic cars. Screw jacks ...

4. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   One of the reasons pneumatic linear actuators are preferred to other types is the fact that the power source is simply an air compressor. Because air is the input source, pneumatic actuators are able to be used in many places of mechanical activity. The downside is, most air compressors are large, bulky, and loud.

5. Jackhammer - Wikipedia

   en.wikipedia.org/wiki/Jackhammer

   The jackhammer is connected with hydraulic hoses to a portable hydraulic powerpack: either a petrol or diesel engine driving a hydraulic pump; or a mini-excavator or skid-steer via a power take-off driveshaft to the machine's hydraulic system. Hydraulic power sources are more efficient than air compressors, making the kit smaller, cheaper or ...

6. Pneumatic tool - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_tool

   A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2 ) stored in small cylinders allowing for portability.
