1. JWM type screw lifter (trapezoidal screw type) is suitable for low-speed and low-frequency occasions. The main components are: precision trapezoidal screw pair and high-precision worm gear pair.
2. Economical price, compact structure, simple operation and convenient maintenance.
3. Low speed and low frequency: Mainly used in places with heavy load, low speed and no frequent work.
4. Maintain the load: The trapezoidal screw has an automatic locking function, and the load can be maintained even if there is no brake device.
  The SWL series worm gear screw lift has many functions such as lifting, lowering, advancing with auxiliary parts, turning, and adjusting various height positions.It is widely used in various industries such as machinery, metallurgy, construction, water conservancy, chemical industry, medical treatment, culture and sports.
  Worm gear screw lift is a basic lifting component, with many advantages such as compact structure, small size, light weight, no noise, safety and convenience, flexible use, high reliability, wide power source, multiple supporting functions, and long service life.It can be used alone or in combination, and can accurately control and adjust the height of the lifting or propulsion according to a certain procedure. It can be directly driven by a motor or other power, or manually.
  In order to improve the efficiency and carrying capacity of SWL worm gear screw lifts, special and advanced technology has been developed to improve the overall performance of the lifts to meet the requirements of our customers.
  The screw lifter has different structure types and assembly types, and the lifting height can be customized according to user requirements.
  technical parameter:
  1. Structure: Type 1 screw rod moves axially; [When the screw rod moves, it is divided into rotating and non-rotating (F), please pay attention to distinguishing when selecting the type] Type 2 screw rod rotates and the nut moves axially.
  2. Assembly type: Type A screw/or nut moves up; Type B screw/or nut moves down
  3. Screw head type: Type 1 structure type screw head: type Ⅰ (cylindrical type), type Ⅱ (flange type), type Ⅲ (thread type), type Ⅳ (flat head type)
  Screw head of type 2 structure: type Ⅰ (cylindrical type), type Ⅲ (thread type)
  4. Transmission ratio: normal speed ratio (P), slow speed ratio (M), medium speed ratio (F) can be customized according to user requirements
  6. Protection of the screw rod: Type 1 structure: basic type (no protection), anti-rotation type (F), with protective cover (Z), anti-rotation connecting shield (FZ), type 2 structure: basic type (no protection)
  Note: The SWL worm gear screw lift has a self-locking function at high speed ratio, but it may fail the self-locking function when subjected to large vibrations or shock loads. At this time, please add a brake device or a brake motor to prevent objects Drop.
