SWL Worm Screw Elevator 

Description:

Screw lift, SWL series worm gear screw jack lift is a basic component, in line with JB/T8809-1998 (original JB/ZQ4391-86) standards. Carrying capacity of the 2.5-120T. Has a compact structure, small size, light weight, power source a wide range, low noise, easy to install, flexible, multi-function, multi-format support, high reliability, long life.
 1, structure type
 Lift divided by structure type: Type 1 - same as the screw rotation and axial movement; 2 - screw for rotation.

Screw on the nut for axial movement.
 2, the assembly type
 Each lift assembly structure type is divided into two types: A type - screw (or nut) to move up; B type - screw (or

nut) down. 3, the screw head type 1 type of screw-type structure
 Head is divided into:
 I (cylindrical), II (flange type), III (screw-type), IV (flat head type) four types. 2 types of screw head structure is

divided into: I (cylindrical) and III (screw type) in two forms. 4, two types of transmission gear ratio than the lift, that is

normal (P) and slow (M). 5, the protective screw screw lift the protective type 1 is divided into: basic, anti-rotation

type (F) and with a shield-type (Z); 2 screw-type lift the protective divided into: basic and belt guard type
