This paper proposes a design method of a long-stroke linear actuator used for vertical lifting. The long-stroke linear actuator is a type of linear actuator that comprises a pair of springs. A spiral spring called "the windup spring" engages teeth on a tooth spring called" the toothed coil spring", thereby forming a solid column and transferring a high power and large displacement while stored by a small assembly located at the base of the column. Working performance of the designed linear actuator is verified through simulation and experiments.
