The SWL series worm screw elevator is a basic lifting component that complies with the JB/T8809-1998 (formerly JB/ZQ4391-86) standard. This product can be widely used in various industries such as machinery, metallurgy, construction, chemical, medical, cultural and health. Carrying capacity of 2.5-120T. It 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. It has functions such as lifting, landing, propulsion, and flipping, and can be used alone or in combination. It can accurately control and adjust the height of lifting or propulsion according to a certain program, which can be directly driven by an electric motor or other power, or manually operated. 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.

Structural type:

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.

Screw head type:

The screw head of Type 1 structural type is divided into 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).

Transmission ratio:

Elevators are divided into two transmission ratios, namely normal (P) and slow (M).

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

Z1: Shield on top, screw on bottom Z2: Screw on top, shield on bottom

The actual bearing capacity of SWL10T worm gear screw elevator is about 3T, with a screw diameter of 58mm and a reduction ratio of 8:1/24:1
