2. Hydraulic jigger - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_jigger

   A hydraulic jigger is a hydraulically-powered mechanical winch. From the mid-19th century, hydraulic power became available throughout the increasingly modern dockyards and warehouses. This was generated centrally and distributed by pipework, either around a dock estate, or across a city by the new hydraulic power networks .

3. Active heave compensation - Wikipedia

   en.wikipedia.org/wiki/Active_heave_compensation

   Hydraulic cranes can use hydraulic cylinders to compensate, or they can utilize a hydraulic winch. [4] [5] Hydraulic "active boost" winches control the oil flow from the pump(s) to the winch so that the target position is reached. Hydraulic winch systems can use accumulators and passive heave compensation to form a semi-active system with both ...

4. Hydraulic machinery - Wikipedia

   The hydraulic fluid reservoir holds excess hydraulic fluid to accommodate volume changes from: cylinder extension and contraction, temperature driven expansion and contraction, and leaks. The reservoir is also designed to aid in separation of air from the fluid and also work as a heat accumulator to cover losses in the system when peak power is ...

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 ...

7. Power transfer unit - Wikipedia

   en.wikipedia.org/wiki/Power_transfer_unit

   In this example, the PTU transfers hydraulic power from the right hydraulic system to the left hydraulic system. A PTU consists of a hydraulic motor paired with a hydraulic pump via a shaft. [1] As the connection is purely mechanical, there is no intermixing of hydraulic fluid between the left and right hydraulic systems during PTU operation.
