Description
1. Structure type
Lifts are divided into structure types:
Type 1-The lead screw makes simultaneous rotation and axial movement;
Type 2-Lead screw for rotating motion. The nut on the screw moves axially.
2. Assembly type
Each structure type of lift is divided into two assembly types:
Type A-the screw (or nut) moves upward;
Type B-the lead screw (or nut) moves down.
3. Screw head type
The screw head of type 1 structure is divided into:
Four types: I (cylindrical type), II (flange type), III (threaded type), IV (flat head type).
The screw head of type 2 structure type is divided into two types: I (cylindrical type) and III (thread type).
4. Transmission ratio
The elevator is divided into two transmission ratios, namely normal (P) and slow (M).
5. Protection of the lead screw
Type 1 elevator screw protection is divided into: basic type, anti-rotation type (F) and protective cover type (Z);
The protection of type 2 elevator screw is divided into basic type and protective cover type (Z).
