I am trying to build a juice press using an electrical linear actuator, instead of a hydraulic car jack (bottle type). If I build it with the hydraulic cylinder I would need a 5 Ton bottle, which according to the online conversion tables, 5 Ton is appx. 44.5 KN which is how the force of Linear Actuators are rated. Is this correct? It seems so much by comparison, I mean, 5 Ton bottle jack is at the bottom of hydraulic cylinders' force scale while a 44482 N Linear Actuator like at the very top of that scale. What am I doing wrong? Am I comparing apples and oranges? Just for the analytically minded persons out there, the actuator will be pushing a 15cm (6in) x 15cm (6in) platform approximately 15-20cm (6-8in) up. Any help with the determination of a right size Linear Actuator comparable to 5T hyd cyl. will be greatly appreciated. Thank you all for your time.
