2. Hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_cylinder

   A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.

3. Jack (device) - Wikipedia

   en.wikipedia.org/wiki/Jack_(device)

   Jack which can lift a mobile home. A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. [1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be ...

4. Hydraulic machinery - Wikipedia

   Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types. Open center circuits use pumps that supply a continuous flow.

5. 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 ...

6. Position-sensing hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Position-sensing_hydraulic...

   The machining and additional production steps associated with “gun drilling” the piston rod can add cost to the finished cylinder. Magnetostrictive LDTs provide extremely high accuracy, down to one micron. [3] Hydraulic cylinder with a Hall effect sensor mounted along its barrel to sense position of a magnetic piston inside. The sensor is ...

7. Strand jack - Wikipedia

   en.wikipedia.org/wiki/Strand_jack

   A strand jack is a hollow hydraulic cylinder with a set of steel cables (the "strands") passing through the open centre, each one passing through two clamps - one mounted to either end of the cylinder. The jack operates in the manner of a caterpillar's walk: climbing (or descending) along the strands by releasing the clamp at one end, expanding ...
