2. Electro-hydraulic actuator - Wikipedia

   en.wikipedia.org/wiki/Electro-hydraulic_actuator

   Electro-hydraulic actuators (EHAs), replace hydraulic systems with self-contained actuators operated solely by electrical power. EHAs eliminate the need for separate hydraulic pumps and tubing, because they include their own pump, [ 1 ] simplifying system architectures and improving safety and reliability.

3. Hydraulic hooklift hoist - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_hooklift_hoist

   The hook latch covers the opening in the hook head, effectively securing the lift bar inside the hook head during transport and dump. It is designed to augment the rear lock system during transit; Some systems utilize proximity switches to indicate to the operator which part of the lift/dump cycle is current, or whether there is a fault in the ...

4. Hoist (device) - Wikipedia

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

   Hoist atop an elevator. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.

5. Hydraulic machinery - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_machinery

   Components of a hydraulic system [sources (e.g. pumps), controls (e.g. valves) and actuators (e.g. cylinders)] need connections that will contain and direct the hydraulic fluid without leaking or losing the pressure that makes them work. In some cases, the components can be made to bolt together with fluid paths built-in.

6. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   Pneumatic and hydraulic cylinders, or lead screws can be designed to generate force in both directions. Mechanical actuators typically convert rotary motion of a control knob or handle into linear displacement via screws and/or gears to which the knob or handle is attached. A jackscrew or car jack is a familiar mechanical actuator.

7. Jack (device) - Wikipedia

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

   A demonstration of using two stacked air bags to lift the rear of a car. An inflatable jack, lifting bag, or pneumatic lifting bag is an air bag that is inflated by compressed air (without a hydraulic component) in order to lift objects. The bag can be deflated to be reused later.

8. Telescopic cylinder - Wikipedia

   en.wikipedia.org/wiki/Telescopic_cylinder

   Telescopic cylinders must only be used in machinery as a device for providing force and travel. Side forces and moment loads must be minimized. Telescopic cylinders should not be used to stabilize a structural component. [4] Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi.

9. Valve actuator - Wikipedia

   en.wikipedia.org/wiki/Valve_actuator

   Electric actuators whose functions have been considerably expanded are also affected by this development. The simplest example is the position control. Modern positioners are equipped with self-adaptation i.e. the positioning behaviour is monitored and continuously optimised via controller parameters.
