The SWL series worm screw elevator, also known as the QWL elevator, is widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment. It has many functions such as lifting, lowering, and using auxiliary components for propulsion, flipping, and various height and position adjustments SWL worm 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 alone or in combination, and can accurately control and adjust the height of lifting or pushing according to a certain program. It can be directly driven by an electric motor or other power, or manually driven. It has different structural and assembly forms, and the lifting height can be customized according to user requirements.

The linkage methods for screw elevators include 2 elevators linkage, 3 elevators linkage, 4 elevators linkage, and 8 elevators linkage, among others. Widely used in industries such as food, pharmaceuticals, chemicals, steel, metallurgy, textiles, plastics, papermaking, and assembly lines. Our main products include SWL worm screw elevators, QWL worm screw elevators, JWM trapezoidal screw elevators, JWB ball screw elevators, TRSS worm screw elevators, JRSS worm screw jacks, SJA spiral screw elevators, SJB ball screw elevators, HK screw elevators, and MA spiral screw elevators

Elevators are classified according to their structural types:
Type 1- The lead screw performs both rotational and axial movements simultaneously;
Type 2- The screw rotates. The nut on the screw moves axially.
Assembly type
Each structural type of elevator is further divided into two assembly types:
Type A - the screw (or nut) moves upwards;
Type B - The screw (or nut) moves downwards.
3. Screw head type
The wire head part of Type 1 structural type is:
There are four types: I (cylindrical type), II (flange type), III (threaded type), and IV (flat head type).
The wire head of Type 2 structural type is divided into:
There are two forms: I (cylindrical) and III (threaded).

4. Transmission ratio
The elevator is divided into two transmission ratios, namely normal (P) and slow (M).
5. Protection of lead screws
The protection of type 1 elevator screw is divided into: basic type, anti rotation transformation (F), and type with protective cover (Z);
The protection of type 2 elevator screw is divided into basic type and type with protective cover (Z).
characteristic
1. The SWL type (trapezoidal screw type) is suitable for low-speed and low-frequency situations, and its main components are: precision trapezoidal screw pairs and high-precision worm gear pairs.
2. Economical price, compact structure, simple operation, and convenient maintenance.
3. Low speed, low frequency: mainly used in places with high loads, low speeds, and no need for frequent work.
4. Maintaining load: The trapezoidal screw has an automatic locking function, which can maintain load even without a braking device.
