2. Differential pulley - Wikipedia

   en.wikipedia.org/wiki/Differential_pulley

   The mechanical advantage at the differential sprocket pair equals ⁠ P 1 / P 1 − P 2 ⁠. Because there is a traveling pulley at the load, this doubles the mechanical advantage of the fixed (anchored) sprocket assembly, leading to a total mechanical advantage of 2 × ⁠ P 1 / P 1 − P 2 ⁠ .

3. Hoist (device) - Wikipedia

   en.wikipedia.org/wiki/Hoist_(device)

   A mining hoist (also known simply as a hoist or winder) [6] is used in underground mining to raise and lower conveyances within the mine shaft. It is similar to an elevator, used for raising humans, equipment, and assorted loads. Human, animal and water power were used to power the mine hoists documented in Agricola's De Re Metallica, published ...

   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.

5. Overhead crane - Wikipedia

   en.wikipedia.org/wiki/Overhead_crane

   Power was transmitted to the crane from a pulley driven by a stationary engine through an endless cotton rope. [3] 1887: The Ludwig Stuckenholz company introduces electrical components to overhead cranes, determining industry design. 1910: The first mass-produced electric motor hoist starts in Germany. Configurations:

   The American Crane Corporation was founded in 1882 as the Franklin Manufacturing Company, and in 1892 the name changed to American Hoist & Derrick. The company manufacturers terrain cranes, crawler cranes and tower cranes. In 1998 American Crane Corporation was acquired by Terex for $27 million. [1]

7. XGC88000 crawler crane - Wikipedia

   en.wikipedia.org/wiki/XGC88000_crawler_crane

   The XGC88000 crawler crane, unlike the majority of crawler cranes, comes in two sections. The primary section consists of the crane itself, which boasts a maximum boom length of 144 meters, a maximum total length of 173 meters (including the counterweight radius), a maximum height (when fully erect) of 108 meters, a lifting capacity ranging between 3,600 and 4,000 tons [10] [11] [12] (although ...
