Spiral Jack RN-30T

Introduction to the Turbo Screw Lift
　　The NOSEN RN series of turbine‑screw lift actuators is a meticulously engineered screw‑type lifting transmission device developed by Luosheng Company. It has been produced as a product line and widely adopted across various industries, earning recognition from mechanical engineers for its distinctive appearance, refined design, compact structure, and fully self‑locking capability. These features make it suitable for applications in machinery, metallurgy, construction, chemical processing, medical equipment, cultural and health‑care sectors, and more. The RN series effectively addresses challenges such as difficult positioning and cumbersome installation in mechanical lifting operations, while also facilitating the integration of auxiliary assemblies into mechanical designs, enhancing both convenience and practicality. The NOSEN turbine‑screw lift consists primarily of a housing, an input worm gear, an alloy worm wheel with internal threads, and various ancillary components. Designed to handle loads ranging from 0.5 to 100 tons, it is available in multiple specifications. Its dynamic load capacity spans 0.2 to 26 tons, with standard models offering a maximum lifting speed of 1,500 mm/min; higher speeds can be customized upon request. Screw‑end configurations include five types: plate‑mounted, bolt‑hole, threaded‑mouth, flat‑mouth, and socket‑type. The NOSEN turbine‑screw lift boasts a small footprint, versatile functionality, lightweight construction, low noise levels, a compact design, easy installation, flexible operation, broad compatibility with power sources, high transmission efficiency, and an extended service life. It supports a wide range of installation and operational modes, including lifting, lowering, raising, pressing, pushing, and flipping. The NOSEN turbine‑screw lift can be used individually or in multi‑unit combinations, enabling precise height control through preprogrammed sequences. It may be driven directly by an electric motor or other power source, or operated manually.

Model Classification
　　The RN series comprises 12 models: RN05T, RN-1T, RN-2T, RN-3T, RN-5T, RN-10T, RN-15T, RN-20T, RN-30T, RN-40T, RN-50T, and RN-100T. It offers three transmission ratios, with speed options of fast, medium, and slow.

Speed trial calculation
　　To increase the lifting speed, you can raise the input rotational speed; the maximum input speed is less than 1,800 rpm. Alternatively, you can customize a lead‑screw with an enlarged pitch or a double‑pitch lead screw. If the lead‑screw drive speed needs to be adjusted, it can be paired with an electric motor; for variable-speed operation, a frequency inverter or a variable-speed motor such as a stepper or servo motor can be used.

Application Examples

NOSEN turbine‑screw lift actuators are used on hydraulic gates. Taking into account the gate’s weight and water pressure, they can be operated either as a single unit or in tandem, with multiple units synchronized. A practical application involves two RN‑20T turbine‑screw lift actuators lifting a 15‑ton gate over a stroke of 3,000 mm at a speed of 25 mm/s, driven by a single 5.5 kW motor that synchronously raises and lowers both actuators.

NOSEN turbine‑screw lift actuators are employed in solar‑power generation systems. A real‑world example is a solar power plant in Spain. Equipped with RN‑3TCHMDR1/24‑670PR turbine‑screw lifts, each unit is driven by a DC motor and, under the control of a sun‑tracking system, rotates the solar panels to follow the sun’s apparent path from sunrise to sunset, thereby maximizing energy output.

NOSEN turbine‑screw lift actuators are used in stage‑lifting systems. A real‑world example is a lifting platform manufactured by a domestic stage‑equipment company for a celebrity concert. Six RN‑10T units were integrated into a synchronized linkage system to raise and lower a 12‑square‑meter stage, delivering safe self‑locking performance, smooth motion, precise positioning, and energy efficiency.

NOSEN worm‑gear screw jacks are used in three‑roll mills for plastic sheet production. In a real‑world application, a customer of the company equipped their three‑roll mill with four RN‑15T worm‑gear screw jacks to achieve synchronized lifting, each driven by a geared motor for gap adjustment. The fine‑tuning accuracy reaches 0.01 mm.

NOSEN worm‑gear screw jacks are employed in glass‑processing equipment. A real‑world example involves a publicly listed company in China’s glass‑manufacturing sector, which utilizes four RN‑10T screw jacks and two cross‑type steering units for synchronized, coordinated operation in an ambient temperature exceeding 200°C. LOUSEN can customize worm‑gear screw jacks to withstand high‑temperature environments.

NOSEN worm‑gear screw jacks are used in the furniture industry. A real‑world example involves a U.S. company that employs screw jacks to raise and lower office desks, using two NOSEN worm‑gear screw jacks for synchronized lifting and lowering, coupled with a hand crank for manual operation. This setup delivers smooth, precise height adjustment and ensures safe self‑locking.

Implement three basic actions:
Achieving a tilting motion: When equipped with a swivel base, the NOSEN screw jack can enable an object to perform a tilting motion about a principal axis.
Achieving horizontal displacement: The NOSEN screw jack with a nut‑and‑screw mechanism features a base‑driven rod; the nut on the screw is connected to the moving load, and horizontal movement of the load is achieved by the nut’s linear displacement as the screw rotates.
Synchronous Lifting and Lowering: A four‑unit linkage system driven by a single motor, with power transmitted via a cross‑turning mechanism, enables the four NOSEN screw‑jack lifts to move in perfect synchrony. The four NOSEN precision screw jacks, along with the couplings and cross‑turning mechanism, are powered by one motor, ensuring consistent synchronization and positioning accuracy within ±0.1 mm.
