Manual Lab-Jack Platforms
The manual lab-Jack works mechanically by having a central screw connected to the central piece of metal between two layers of crossing metal pieces. The screw performs the same task as screws in hydraulic car lift, supporting the metal pieces in withstanding the oppressing weight. Turning the screw increases and decreases the angle between the metal pieces, resulting in extension and contraction of the platform height. It is acting as an adjustable lift using the scissors mechanism. Z axis precision stages that achieve extremely high parallelism using OptoSigma’s unique technology.
