Overview
SJA spiral screw elevator (SJA spiral elevator) is widely used in industries such as machinery, construction, water conservancy, metallurgical equipment, etc. It has many functions such as lifting, lowering, pushing with auxiliary parts, flipping, and height position adjustment
Product Details
SJA worm gear screw lifter（SJA spiral elevator）It 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.
SJA screw lifter（SJA spiral elevator）Characteristics
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
The unique square groove shell of the elevator increases the heat dissipation capacity of the shell and extends the service life of the lubricating grease. The selection of ductile iron shell material significantly improves the strength and performance of the shell, as well as its wide application at high/low temperatures. Using a square tail cover design to control the screw not to rotate. Advanced processing equipment and assembly technology are the guarantee of high product quality. Advanced design concepts create high-quality products with strong impact resistance, high strength, low noise, long life, and small size.
The modular combination enriches the product's combination changes. The spiral elevator can be directly combined with any combination of motor/reducer motor/special function accessories, with an integrated design, providing customers with thousands of easy choices.
We can design non-standard products according to customer requirements, such as stainless steel shells and screw spiral elevators, multi head screws, low temperature resistance, high temperature resistance, etc.
