SJ turbine screw lift | SJ spiral lift

1. Overview: SJ series worm gear screw elevator is a micro screw elevator product professionally produced by our company. SJ screw elevator is a basic lifting component with many advantages such as compact structure, small volume, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, 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 directly driven by an electric motor or other power, or manually operated. It has different structural and assembly forms, and the lifting height can be customized according to user requirements. Therefore, it is widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment, and has many functions such as lifting, lowering, pushing with auxiliary components, flipping, and adjusting various height positions.

2. Model, Type, and Marking:

2. SJ type is the basic type, which means the input method is input shaft type; SJD is a flange type with motor:

2. 2 input methods: There are three types of SJ input methods, type i is right axis input, type ii is left axis input, and type iii is dual axis input. There are four types of SJD input methods: Type I is right flange input, Type II is left flange input, Type III is right direct input, and Type IV is left direct input.

2. 3. Screw head types: There are four types of screw head types: R-type (cylindrical), H-type (flat head), S-type (threaded), and T-type (flange).

2. 4 Installation methods: Type A (screw rotation moves upwards), Type B (screw rotation moves downwards), Type C (screw rotation moves upwards without rotation), Type D (screw rotation moves downwards without rotation), Type E (screw rotation nut moves upwards), Type F (screw rotation nut moves downwards).

2. 5 specifications: Divided into 10 types based on lifting force (ton T): 2, 3, 5, 10, 15, 20, 30, 40, 50, 100 tons T10.

2. 6. Transmission ratio
Elevators are divided into two transmission ratios, namely normal (p) and slow (m).
2. 7. Protection of lead screw
The protection of type 1 elevator screw is divided into basic type, anti rotation transformation (f), and protective cover type (z);
The protection of type 2 elevator screw is divided into basic type and type with protective cover (z).

2. 8. Marking Example:
