Welcome to inquire! Contact: Zhang Yan. SWL screw lift capable of self-locking screw lift swl1, it is divided into different forms according to different structures: one, SWL screw lift structure type lift by structure type is divided into: a type - screw while rotary motion and axial movement; Type 2 - screw for rotary motion. Nut on the screw for axial movement. Two, SWL screw lift assembly type screw lift each structure type is divided into two assembly type: A type - screw (or nut) to move up; B type - screw (or nut) to move downwards. Three, SWL screw lift a type of screw head type structure type of screw head is divided into: I (cylindrical), II (flange type), III (screw-type), IV (flat head type) four types . Type 2 structure type of screw head is divided into: I (cylindrical) and III (screw type) in two forms. Four, SWL screw lift lifts ratio of two ratios jwm005 screw lift, namely general (P) and slow (M) divided. Five, SWL screw lift screw protection. Type 1 lift screw protection is divided into: basic, anti-rotation type (F) and with a shield-type (Z); type 2 lifts screw protection is divided into: basic and belt guard type (Z). Body size: SJ2.5 ~ SJ500 total of 9, followed by the lifting force 5KN ~ 500KN. Ratio of 1: 7-- common ratio; 1: 21-- Slow ratio. A structure type - screw for axial movement without rotation; B Type - nut to move axially, the screw rotational movement.
