2. 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.

3. Engine crane - Wikipedia

   en.wikipedia.org/wiki/Engine_crane

   The electric chain hoist, also known as the "electric hoist", is the least used type of engine crane. The operation is similar to the chain hoist in the way that chains are used to lift the engine. The electric chain hoist uses an electric motor operated by remote control to lift the engine, unlike the chain hoist where the operator has to ...

4. Rigid chain actuator - Wikipedia

   en.wikipedia.org/wiki/Rigid_chain_actuator

   A rigid chain actuator, known variously as a linear chain actuator, push-pull chain actuator, electric chain actuator or column-forming chain actuator, is a specialized mechanical linear actuator used in window operating, push-pull material handling and lift applications. The actuator is a chain and pinion device that forms an articulated ...

   Counter jib: holds counterweights, hoist motor, hoist drum and the electronics. (In many older tower crane designs the hoisting devices and electronics were located in the mast foot.) [ 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 ...

6. Material-handling equipment - Wikipedia

   en.wikipedia.org/wiki/Material-handling_equipment

   Manipulators act as “muscle multipliers” by counterbalancing the weight of a load so that an operator lifts only a small portion (1%) of the load's weight, and they fill the gap between hoists and industrial robots: they can be used for a wider range of positioning tasks than hoists and are more flexible than industrial robots due to their ...

7. Elevator - Wikipedia

   en.wikipedia.org/wiki/Elevator

   An elevator (American English) or lift (Commonwealth English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack.
