screw liftAdopting a mechanical synchronous lifting system, the screw lift nut adopts a safety nut design to monitor the wear condition of the product, eliminate hidden dangers, and combine with a reduction motor and various accessory modules to meet any customer requirements. The thrust range is 500 kg to 30 tons. Use different screw specifications within this range. Adopt an appropriate screw transmission ratio. The size and stroke of the thrust determine the thickness, weight, and standard of the screw.

Selection precautions:

The working system is the percentage of working time within 10 minutes. The working system of SJA series ordinary tooth spiral elevators is 30%. The working system of ball screw spiral elevators is 50%. When the actual load is less than the rated load, the working system of SJA50 spiral elevators can be appropriately increased.

The SJA worm gear screw elevator (SJA spiral elevator) is a basic lifting component that has 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.

Product features of SJA spiral screw elevator:

Push rod speed: up to 75mm/s;

Input speed: 1800rpm; When the actual load is between 25% and 100% of full load (i.e. load rate of 25% -one hundred percent）Spiral elevator requires input torque=load rate X full load torque

When the stroke is greater than 300mm, stability should be checked. Please refer to the load and stroke stability curve chart for verification.

Adjust the selection safety factor according to the load type. Uniform load 1.0-1.2: Moderate load 1.3-1.5; Heavy load 1.6-2.5

Travel range: up to 6.5 meters;

The standard product accuracy can reach 0.1mm, and the accuracy with anti backlash accessories can reach 0.04mm,

High mechanical synchronization accuracy, smooth operation,

Strong impact resistance,

We can provide double headed screw, triple headed screw, ball screw spiral elevator. And all must use safety screw lift nuts. To ensure a higher safety factor.

Technical parameters and characteristics of SJA spiral elevator

The unique square groove shell of SJA spiral 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. 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 products with strong impact resistance, high strength, low noise, long life, and small size.

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. For specific parameters, please consult Wanxin Transmission.

We can design non-standard products according to customer requirements, such as stainless steel shells and screw spiral elevators, multi head screws, high temperature resistance, low temperature resistance, etc.

Complete accessories: dust cover, anti backlash design, safety nut, ball screw, limit switch, overload clutch, potentiometer, encoder, brake, hand crank, installation accessories, etc.
