3. International Loadstar - Wikipedia

   en.wikipedia.org/wiki/International_Loadstar

   Air over hydraulic and full air brakes were available. A driven front axle and tandem rear axles were available on some models (cab-over-engine models could have neither). Loaded weights were from 18,200 to 30,200 pounds (8,300 to 13,700 kg) and up to 50,000 pounds (23,000 kg) including trailers.

4. 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 ...

5. Hydraulic transmission - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_transmission

   Hydrostatic transmission, using hydraulic motors to convert the fluid energy into rotary propulsion; Hydraulic drive system § Hydraulic cylinder, using hydraulic rams acting on a swashplate or crank to convert the fluid pressure into rotation; Hydrokinetic transmission, involving one or more torque converters; commonly used in railway locomotives

6. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   The displacement is only along the axis of the piston. A familiar example of a manually operated hydraulic actuator is a hydraulic car jack. Typically though, the term "hydraulic actuator" refers to a device controlled by a hydraulic pump.

7. Hydraulic power network - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_power_network

   Only a few hydraulic power transmission networks are still in use; modern hydraulic equipment has a pump built into the machine. In the late 19th century, a hydraulic network might have been used in a factory, with a central steam engine or water turbine driving a pump and a system of high-pressure pipes transmitting power to various machines.
