There are different structural types and assembly methods, and the height is manufactured according to the user's requirements. The screw lift is divided into two assembly types: Type A - the screw (or nut) moves upwards; Type B - The screw (or nut) moves downwards. Models of screw lifts: SWL2.5, SWL5, SWL10, SWL15, SWL20, SWL25, SWL35, SWL50; JWM002、JWM005、JWM010、JWM025、JWM050、JWM100、JWM150、JWM200、JWM300、JWM500、JWM750、JWM1000
