Standard Screw Jacks: Industrial Lifting Solutions (10kN – 1000kN)

1. Product Overview

Our Standard Screw Jack series is the result of intensive research and development by a leading manufacturer in the power transmission industry. With specialized expertise, we provide a highly reliable lifting device featuring a robust structure that meets the most stringent standards in heavy industry and automation.

2. Key Technical Features

  • Wide Load Range: Capacities ranging from 10 kN to 1000 kN, suitable for systems of all scales.

  • Self-locking Mechanism: The perfect combination of high-precision worm gears and trapezoidal screws ensures the load is held safely at any position without the need for additional braking systems.

  • Effective Anti-rotation: Screws are made from high-grade carbon steel. Optional keyways and anti-rotation pins provide precise control over linear motion.

  • Durable Operation: The reduction mechanism is lubricated with standard grease to reduce friction, ensure low noise, and extend operational lifespan.

  • Diverse Accessory Ecosystem: Flexible integration with bellows (dust covers), handwheels, trunnion bases, limit switches, and RC encoders for automated control.
