JWM spiral elevator is a basic lifting component, which has many advantages such as compact structure, small size, light weight, wide power source, no noise, convenient installation, flexible use, multiple functions, multiple supporting forms, high reliability, long service life, etc advantage. It can be used singly or in combination. It can accurately control the height of the lifting or advancing according to a certain program. It can be directly driven by a motor or other power, or it can be manually operated. It has different structural forms and assembly forms, and the lifting height can be customized according to user requirements.
| 1. Spiral elevator (trapezoidal screw type) is suitable for low-speed, 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: It is mainly used in places with large load, low speed and frequent work.
4. Holding load: The trapezoidal lead screw has an automatic lock function, which can maintain the load even without a braking device.
Note: When receiving large vibration and shock load, the self-locking function may be disabled. In this case, please add a braking device.
