2. Hydraulic jigger - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_jigger

   Hydraulic fluid was then pumped from the catch tank by an electric pump and back into the cylinder under pressure. The cylinder was double-ended, with a piston rod and jigger at each end, and the catapult was retracted by the hydraulic pressure forcing the piston backwards, and re-compressing the air reservoirs.

3. Active heave compensation - Wikipedia

   en.wikipedia.org/wiki/Active_heave_compensation

   [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 an active and a passive component. In such systems the active part will take over when the passive ...

4. Shuttle valve - Wikipedia

   en.wikipedia.org/wiki/Shuttle_valve

   Winch brake circuit: a shuttle valve provides brake control in pneumatic winch applications. When the compressor is operated the shuttle valves direct air to open the brake shoes. When the control valve is centered, the brake cylinder is vented through the shuttle valve, and the brake shoes are allowed to close. [clarification needed]

5. Hydraulic motor - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_motor

   Hydraulic motors usually have a drain connection for the internal leakage, which means that when the power unit is turned off the hydraulic motor in the drive system will move slowly if an external load is acting on it. Thus, for applications such as a crane or winch with suspended load, there is always a need for a brake or a locking device.

6. Winch - Wikipedia

   en.wikipedia.org/wiki/Winch

   An air winch, sometimes known as an air hoist or air tugger, is an air-powered version of a winch. It is commonly used for the lifting and the suspension of materials. In the oil and gas, construction , and maritime industries, air winches are frequently preferred to electric, diesel, and hydraulic winches because of their durability ...

7. Anchor windlass - Wikipedia

   en.wikipedia.org/wiki/Anchor_windlass

   The combined port anchor windlass and winch of the modern ferry Stena Britannica. The hydraulically operated brake and pawl allows the anchor to be dropped from the ship's bridge. [citation needed] A windlass is a machine used on ships that is used to let-out and heave-up equipment such as a ship's anchor or a fishing trawl. On some ships, it ...
