There are three key data with which you roughly describe a linear actuator. First of all is load capacity. It does not make any sense if the linear actuator even can not lift up the subject you want it to. Our heavy duty linear motor HB-DJ805, one member of our industrial family, is able to lift up to 1.2 tons easily, even in harsh working conditions outdoor. https://www.hbactuator.com/heavy...y-duty-linear-motor.html
