SWL series worm gear screw lift application industry introduction:

The product can be widely used in machinery, metallurgy, construction, chemical, medical, cultural and health industries.The carrying capacity is 2.5-120T.It has the advantages of compact structure, small size, light weight, wide power source, low noise, convenient installation, flexible use, multiple functions, multiple matching forms, high reliability, and long service life.It has the functions of lifting, landing, advancing, turning, etc., and can be used alone or in combination.It can accurately control and adjust the height of lifting or pushing according to a certain procedure, and it can be directly driven by a motor or other power, or manually.The high input speed is 1500r/min, and the maximum lifting speed is 2.7m/min.There are different structural types and assembly methods, and the lifting height is manufactured according to user requirements.The device can be self-locking.

SWL series worm gear screw lift model type and mark

1. Structure type

The elevator is divided into:
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 the elevator 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:
I (cylindrical type), II (flange type), III (thread type), IV (flat head type) four types.

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 ordinary (P) and slow (M).

5. Protection of the lead screw

The protection of type 1 elevator screw 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).
