WPT spiral elevatorIt has the advantages of compact structure, small volume, light weight, wide power source, low noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, and long service life.

2. Purpose:

The maximum input speed is 1500r/min, and the maximum lifting speed is 2.7m/min. There are different structural types and assembly methods, and the height is manufactured according to the user's requirements. This device can be self-locking.

3. Type:

structural style

Elevators are classified according to their structural types:

Type 1- simultaneous rotation and axial movement of the screw;

Type 2- Screw rotates. The nut on the screw rod moves axially.

Assembly type

Each structural type of elevator is 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

Type 1 structural screw

The head is divided into

There are four types: I (cylindrical type), II (flange type), III (threaded type), and IV (flat head type).

The screw head of Type 2 structural type is available in two forms: I (cylindrical type) and III (threaded type).

4. Transmission ratio:

1:8 1:12 1:24 1:30 1:40 1:50

5. Protection of screw rod:

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 screws is divided into basic type and shielded type (Z).

4 Characteristics:

1. The JWM type (trapezoidal screw type) is suitable for low-speed and low-frequency applications, and its main components are precision trapezoidal screw pairs and high-precision worm gear pairs.

2. Economical price, compact structure, easy operation, and convenient maintenance.

3. Low speed and low frequency: mainly used in places with high loads, low speeds, and no need for frequent work.

4. Maintain load: The trapezoidal screw has an automatic locking function, which can maintain load even without a braking device.
