Product Details

SJA50 spiral elevatorIt is a basic lifting component with many advantages such as compact structure, small volume, light weight, wide power source, easy installation, no noise, multiple functions, multiple supporting forms, flexible use, high reliability, and long service life.

Characteristics of SJA spiral elevator:

Thrust range: 0.5-30 tons

The stroke can reach 8m, and the stability of the screw and the guiding mechanism need to be considered

30% work schedule, if the load rate is low, the work schedule can be appropriately increased

The lifting speed is less than 1500mm/min (23mm/s), and in special circumstances it can reach 46mm/s

- Efficiency less than 33%, with self-locking function, definitely self-locking for high reduction ratio L1

- Accurate positioning, with an additional anti backlash device that can achieve an accuracy of up to 0.05mm

- High synchronization, the same motor can drive multiple spiral elevators simultaneously, mechanical synchronization

- Can be equipped with encoders, limit switches, dust covers, safety nuts, reducers, ordinary motors, servo motors, stainless steel materials, etc

- Simple operation and maintenance, low noise
