SJD screw lift

SJ worm gear screw liftIt is a motion unit composed of a worm gear reducer and a screw nut pair cleverly combined together. It can be used alone or combined quickly through connectors like building blocks to achieve movements such as lifting, reciprocating, flipping, etc. of objects. SJ precision spiral elevator has been widely used in various industries as a functional component. For example, transmission devices and CNC actuators in the mechanical industry; Roll motion devices in the metallurgical industry, ladle lifting and flipping devices in steel mills, and motion transmission devices in places beyond human reach; Vehicle lifting frames, large flexible clamping, indexing fixtures, welding robots, etc. in the railway vehicle industry; Lifting devices and automatic or remote control opening devices for large doors and windows in the construction industry; Gate opening devices, radar and solar remote sensing devices for water conservancy and other industries; Lifting devices for medical equipment, lifting stages, and automotive manufacturing industries; And transmission devices for aerospace, defense and military industries, etc. In fact, worm gear screw elevators can be used almost anywhere where mechanical displacement transmission is required.
The SJD precision screw lift developed by our company adopts a unique square shell, which makes its structure very compact, small in size, light in weight, and extremely easy and flexible to install. It can be installed on all sides, with various installation methods. When multiple units are used, the position is compact, neat, and beautiful. There are two types of square shell materials: aluminum alloy and cast iron (aluminum alloy materials are generally selected for specifications below 25KN, but can also be customized according to user requirements). SJ precision screw lift has the advantages of low noise, high reliability, wide power source, diverse functions, and long service life. It can be used individually or in combination, and can accurately control and adjust the height of lifting or propulsion according to a certain program; It can be driven directly by a motor or other power source, or manually; There are multiple assembly methods to choose from, and the height can be customized according to user requirements. The elevator can self lock when the power is removed.

Specification of screw elevator body:
Divided into 9 types: SJ2.5-SJ500, with lifting forces ranging from 5KN to 500KN.
Drive ratio of screw lift
1: 7- Normal speed ratio;
1: 21- Slow speed ratio.
Structural form:
Type A - The screw moves axially without rotating;
Type B - The nut moves axially and the screw rotates.
Screw joint type:
The screw head part of the A-type structural form is divided into five types: Type 1 (cylindrical), Type 2 (flange), Type 3 (threaded), Type 4 (flat head), and Type 5 (open);
There are two types of screw heads in the B-type structural form: Type 1 (cylindrical) and Type 0 (without joints).
Additional requirements (optional):
There are three additional requirements for the A-type structural form: ball screw type (B), with anti rotation device (P), and with protective cover (S);
The additional requirements for the B-type structural form include two types: ball screw type (B) and with protective cover (S).
Method of representing screw lift:
SJ10-1:7-A-3-500-BS
SJ represents the elevator series code, and 10 represents the bearing capacity (KN); 1: 7 represents the transmission ratio; A represents the structural form; 3 represents the type code of screw joint; 500 represents travel distance (mm); BS stands for Supplementary.
