2. Hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_cylinder

   The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called the gland) where the piston rod comes out of the cylinder. The piston has sliding rings and seals.

3. Telescopic cylinder - Wikipedia

   en.wikipedia.org/wiki/Telescopic_cylinder

   Telescopic cylinder. Telescopic cylinders are a special design of a hydraulic cylinder or pneumatic cylinder as well as pulley system which provide an exceptionally long output travel from a very compact retracted length. Typically the collapsed length of a telescopic cylinder is 20 to 40% of the fully extended length depending on the number of ...

4. Hydraulic diameter - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_diameter

   The hydraulic diameter, DH, is a commonly used term when handling flow in non-circular tubes and channels. Using this term, one can calculate many things in the same way as for a round tube. When the cross-section is uniform along the tube or channel length, it is defined as [1][2] where. P is the wetted perimeter of the cross-section.

5. Hydraulic hooklift hoist - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_hooklift_hoist

   Hydraulic hooklift hoists are mounted on heavy duty trucks to enable hauliers to change out flatbeds, dumpster bodies, and similar containers. Primarily used in conjunction with tilt frame bodies and specialised roller containers, generally designed for the transportation of materials in the waste, recycling, scrap and demolition industries, as ...

6. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   Mechanical linear actuators typically operate by conversion of rotary motion into linear motion. Conversion is commonly made via a few simple types of mechanism: Screw: leadscrew, screw jack, ball screw and roller screw actuators all operate on the principle of the simple machine known as the screw. By rotating the actuator's nut, the screw ...

7. Hydraulic machinery - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_machinery

   Hydraulic machinery. A simple open center hydraulic circuit. An excavator; main hydraulics: Boom cylinders, swing drive, cooler fan, and trackdrive. Fundamental features of using hydraulics compared to mechanics for force and torque increase/decrease in a transmission. Hydraulic machines use liquid fluid power to perform work.
