Enhances operational safety

6. Durable Construction
High-strength alloy steel worm and screw
Precision-machined worm gear
Heavy-duty housing for structural rigidity

Product Advantages
• Precise Linear Positioning: The translating type structure enables controlled, accurate vertical displacement, making it suitable for positioning systems where repeatability and stability are critical.
• Reliable Mechanical Performance: The worm gear transmission ensures smooth torque conversion and stable motion control, even under high loads and intermittent duty cycles.
• Low Maintenance Operation: The mechanical design reduces dependence on complex hydraulic or pneumatic systems, minimizing maintenance requirements and operational costs.
• Flexible Drive Options
The screw jack can be operated by:
○ Electric motors
○ Gear motors
○ Hand wheels
○ Coupled drive shafts for synchronized multi-point lifting
• Easy System Integration: Its compact structural design and multiple mounting configurations allow seamless integration into lifting platforms, structural frames, and automated systems.
