2. Winch - Wikipedia

   en.wikipedia.org/wiki/Winch

   The winch is made of cable made up of a braided synthetic rope, or a steel cable wrapped around a motorized drum. Each is controlled electronically, allowing the operator to control the winch speed. [5] Modern vehicles typically use electric winches running off the car's 12V starter or 24V secondary battery. The winch is either controlled with ...

3. Level luffing crane - Wikipedia

   en.wikipedia.org/wiki/Level_luffing_crane

   The first of these systems used mechanical clutches between luffing and hoist drums, giving simplicity and a "near level" result. [5] Later systems have used modern electronic controls and quickly reversible motors with good slow-speed control to the hoist winch motors, so as to give a positioning accuracy of inches.

4. Warn Industries - Wikipedia

   In the late 1950s, Warn Industries pioneered the development of the electric winch for use on a recreational vehicle. Previous to the electric winch, most users of four-wheel drive vehicles utilized a winch driven by a power take-off (PTO) system of hydraulic system. However, PTO and hydraulic winches will only operate if the vehicle is running ...

5. Active heave compensation - Wikipedia

   en.wikipedia.org/wiki/Active_heave_compensation

   In an electric winch system, the wave movement is compensated by automatically driving the winch in the opposite direction at the same speed. The hook of the winch will thus keep its position relative to the seabed. AHC winches are used in ROV-systems and for lifting equipment that is to operate near or at the seabed. [3]

6. 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.

7. Crane (machine) - Wikipedia

   Counter jib: holds counterweights, hoist motor, hoist drum and the electronics. [65] Hoist winch: the hoist winch assembly consists of the hoist winch (motor, gearbox, hoist drum, hoist rope, and brakes), the hoist motor controller, and supporting components, such as the platform. Many tower cranes have transmissions with two or more speeds.
