Produced by Wuqiao Weiheng Gearbox Co., LtdSJAScrew rodlift（SJA spiral elevator）Widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment, it has many functions such as lifting, lowering, and using auxiliary components to push, flip, and adjust various heights and positions.

SJA screw lift（SJAScrew Jack）It is a basic lifting component with many advantages such as compact structure, small volume, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, and long service life.

SJA screw lift（SJA Spirallift）Characteristics

Thrust range:0.5-30 tons
The journey can reach up to 8m, which needs to be consideredlead screwStability and guiding mechanism
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, absolute 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
- Absolute synchronization, sameelectrical machineryCan drive multiple spiral elevators simultaneously, mechanically synchronized
- Can be equipped with encoders, limit switches, dust covers, safety nuts, reduction motors, regular motors, servo motors, stainless steel materials, etc
- Simple operation and maintenance, low noise

SJAScrew rodliftThe unique square groove shell 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 ability to withstand high temperatures/Widely used at low temperatures. Square tail cover design, controlling the screw to not 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.

Modular combination enriches the product's combination changes, and the spiral elevator can be directly connected to the motor/Any combination of deceleration motors/special function accessories, integrated design, providing customers with thousands of easy choices.

Can be customized according to customer requirements for non-standard design Produce various non-standard elevators，To meet the different needs of customers.
