Screw elevator

The SWL series worm screw elevator is a basic lifting component that complies with the JB/T8809-1998 (formerly JB/ZQ4391-86) standard. 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.

Usage: This product can be widely used in various industries such as machinery, metallurgy, construction, chemical, medical, cultural and health. 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
1. Structural type
Elevators can be divided into two types based on their structural types: Type 1- screw simultaneously rotates and moves axially; Type 2- Screw rotates. The nut on the screw moves axially.
2. Assembly type
Each structural type of screw lift is divided into two assembly types: Type A - the screw (or nut) moves upward; Type B - The screw (or nut) moves downwards.
3. 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). 4. The transmission ratio elevator is divided into two types of transmission ratios, namely normal (P) and slow (M). 5. Protection of screw. The protection of the screw of type 1 elevator is divided into basic type, anti rotation transformation (F) and shielded type (Z); The protection of type 2 elevator screw is divided into basic type and type with protective cover (Z).
