The transfer device's arm lifting mechanism used an air cylinder, but due to the customer's overall energy-saving policy at the factory, a reduction in power consumption was required. Therefore, we considered developing a new model that would replace the air cylinder with an electric mechanism. A product was needed that could meet both the required thrust of 15kN or more to lift heavy objects and an operating speed of 200mm/s to avoid reducing productivity, but general screw jacks and rack drive units could not meet these requirements.

By adopting Linispeed Jack with a maximum allowable thrust of 50kN and an operating speed of 200mm/s per unit, we overcame the challenging requirement of high-speed lifting and lowering of heavy objects using electric equipment. Replacing air-driven systems resulted in significant power consumption reductions. Furthermore, because Linispeed Jack have their main components as units, complex mechanism design and component selection combining Ball screw and servo motors were eliminated, minimizing design and installation man-hours and enabling the smooth completion of new model development.
