2. Lift table - Wikipedia

   en.wikipedia.org/wiki/Lift_table

   The most common lift table design incorporates hydraulic cylinders and an electrically powered pump to actuate the scissor lifting mechanism. Lift tables can also be driven by pneumatic sources, trapezoidal-threaded screw drives, push chains or by hydraulic foot pump when the load is not heavy. The choice of drive mechanism depends on factors ...

3. Scissors mechanism - Wikipedia

   en.wikipedia.org/wiki/Scissors_mechanism

   This mechanism is used in devices such as lift tables and scissor lifts.Modern low-profile computer keyboards make an extensive use of it as well, installing each key on a scissor support to ensure their smooth vertical movement, allowing the use of a cheap and reliable rubber dome contact set, instead of expensive and complex array of mechanical switches.

4. Electro-hydraulic actuator - Wikipedia

   en.wikipedia.org/wiki/Electro-hydraulic_actuator

   Electro-hydraulic actuators (EHAs), replace hydraulic systems with self-contained actuators operated solely by electrical power. EHAs eliminate the need for separate hydraulic pumps and tubing, because they include their own pump, [1] simplifying system architectures and improving safety and reliability. This technology originally was developed ...

5. Helical band actuator - Wikipedia

   en.wikipedia.org/wiki/Helical_band_actuator

   A helical band actuator, generally known by the trademark Spiralift, is a complex and specialized linear actuator used in stage lifts and material handling lifts. The actuator forms a high-capacity telescoping tubular column (lifting capacities to 25,000 pounds, travel to 40 feet).

6. Jack (device) - Wikipedia

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

   A hydraulic jack uses hydraulic power. [1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). Industrial jacks can be rated for many tons of load.

   Replacing an advertising poster in London using an aerial work platform. An aerial work platform (AWP), also an aerial device, aerial lift, boom lift, bucket truck, cherry picker, elevating work platform (EWP), mobile elevating work platform (MEWP), or scissor lift, is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height.
