2. 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.

4. 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.

5. Hydraulic machinery - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_machinery

   Common types of hydraulic pumps to hydraulic machinery applications are: Gear pump: cheap, durable (especially in g-rotor form), simple. Less efficient, because they are constant (fixed) displacement, and mainly suitable for pressures below 20 MPa (3000 psi). Vane pump: cheap and simple, reliable. Good for higher-flow low-pressure output.

6. Auxiliary hydraulic system - Wikipedia

   en.wikipedia.org/wiki/Auxiliary_hydraulic_system

   An auxiliary hydraulic system delivers pressurized hydraulic fluid from a hydraulic pump to operate auxiliary equipment or attachments. The addition of an auxiliary hydraulic system to heavy construction equipment increases the versatility of the vehicle by allowing it to perform additional functions with different attachments.

7. Hydraulic rescue tool - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_rescue_tool

   The most commonly used source is a separate power unit, small petrol (gasoline) engine connected to a hydraulic pump. [citation needed] The hydraulic fluid is pressurised in the pump and conveyed in a hose under pressure to the tool. Alternative power sources are a small electrical pump in the tool powered by a heavy-duty rechargeable battery ...
