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 such as load capacity, lifting height, speed requirements, and the intended environment. Lift tables can be mounted in a pit for floor-level ...
The two bow rollers can be used together with linear hydraulic pullers to achieve a dynamic lift of 150 tons. The stern rollers can be used with the automatic towing machine to provide a dynamic lift of 150 tons. All four rollers can be used together for a dynamic lift of 300 tons [8] or a static tidal lift of 350 tons. [11]
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.
