Solar Panel Tilt and Tracking Systems
India's rapid expansion of solar energy has driven demand for precision positioning systems that adjust panel tilt angles throughout the day to maximize solar irradiance capture. Single-axis and dual-axis solar trackers use screw jacks for load-holding and smooth positioning.
Application Details: Modern solar farms track the sun's position from sunrise to sunset, moving panels continuously. A typical 10 MW installation uses 40,000–50,000 panels arranged in groups of 20–30, each group driven by synchronized screw jacks. AG-SJ-25 to AG-SJ-100 jacks provide the lifting capacity (25–100 kN) needed for panel clusters weighing 5–15 tonnes.
Why Screw Jacks? The self-locking property ensures panels hold their position even during sudden wind gusts or power loss—critical for safety and equipment protection. Synchronized multi-jack systems using bevel gearboxes ensure uniform tilting across all panels without electronic feedback or load sensors. Operating temperatures from 40°C (winter) to 80°C (summer) are managed by AEI jacks' sealed design.
Steel Mill Roll Gap Adjustment
Steel rolling mills producing flat steel, wire rod, and structural shapes use screw jacks to adjust the gap between rotating rolls—a precision measurement affecting product thickness and quality. Gap adjustment occurs both during setup and continuously during rolling operations.
Application Details: A typical hot rolling mill has upper and lower roll stands with individual adjustment points. AG-SJ-150 to AG-SJ-300 jacks (150–300 kN) lift the entire upper roll assembly, supporting loads of 50–100 tonnes. During continuous operation, fine adjustments maintain product thickness within ±0.5 mm tolerances.
Why Screw Jacks? Self-locking holds the rolls precisely in place while the mill operates, eliminating drift. Ball-screw variants provide smooth, quiet operation compared to hydraulic systems that generate heat and noise in the high-temperature mill environment. AEI's high-temperature variants with Viton seals rated to 200°C withstand the heat from rolling operations.
Theatre and Performance Venue Stage Machinery
Modern performing arts venues from the National Centre for the Performing Arts (NCPA) in Mumbai to regional theatres throughout India use synchronized screw jack systems for stage lighting, scenery movement, and orchestra pit platforms.
Application Details: A typical theatre uses AG-SJ-10 to AG-SJ-50 jacks (10–50 kN capacity) synchronized in groups of 4–8 to smoothly lift and lower stage elements ranging from 1–10 tonnes. The orchestra pit rises and falls silently (unlike hydraulic systems which hiss and drip), and the synchronized mechanics ensure perfectly level platforms—critical for performer safety and equipment protection.
Why Screw Jacks? The silent operation (worm gears run quietly compared to hydraulic pumps) is essential in theatres where audience noise must be controlled. Self-locking prevents platforms from dropping if power is lost during a performance. Trapezoidal screw jacks (not ball screws) are preferred because they inherently hold load position without external brakes. No hydraulic fluid leakage protects scenery, lighting equipment, and performers from oil contamination.
Dam Gate and Water Management Systems
India's extensive network of dams and irrigation infrastructure uses large screw jack systems for sluice gates, spillway controls, and weir adjustments. These applications involve extreme loads and corrosive water environments requiring specialized materials and maintenance protocols.
Application Details: Major dam systems use AG-SJ-250 to AG-SJ-350 jacks (250–350 kN) in synchronized banks of 4–12 units to lift sluice gates weighing 100–500 tonnes. Slow, controlled lifting prevents pressure spikes, cavitation, or water hammer damage to concrete structures. Gates can hold position indefinitely without drifting.
Why Screw Jacks? AEI's corrosion-resistant AISI 316 stainless steel versions with Niploy coating withstand constant water exposure and prevent rust staining on dam faces. The self-locking property is essential—if an operator releases the control lever, the gate stops instantly rather than free-falling. Synchronized mechanical linkage ensures gate raises evenly across all lift points, preventing jamming or uneven loading on the concrete structure.
Industrial Platform Levelling and Load Equalization
Manufacturing facilities, warehouses, and heavy equipment operations use synchronized screw jack systems to level work platforms, adjust assembly fixtures, and equalize load distribution on machinery support structures.
Application Details: A precision machining facility uses four AG-SJ-50 jacks synchronized to support a 20-tonne assembly platform. The operator controls a single motor; mechanical linkage through connecting shafts and bevel gearboxes distributes power equally to all four jacks, maintaining perfect levelness even if individual loads shift slightly.
Why Screw Jacks? Mechanical load equalization requires no sensors, controllers, or electronic feedback—the rigid connecting shafts automatically compensate for load variation. If one corner bears slightly more load, the rigid linkage distributes that load proportionally to all jacks. This passive self-equalizing capability is impossible with independent hydraulic jacks which would require feedback pressure compensators (expensive and complex).
Why Industries Choose AEI Screw Jacks
1. Comprehensive Capacity Range: From AG-SJ-05 (5 kN) for laboratory equipment to AG-SJ-350 (350 kN) for heavy industrial machinery, we cover the full spectrum of lifting requirements without over-specification.
2. Reliability in Harsh Environments: AEI manufactures stainless steel variants for coastal/corrosive environments, high-temperature variants (Viton seals, synthetic lubricants) for foundry/furnace applications, and food-grade variants with NSF H1 lubricants.
3. Synchronized Multi-Jack Systems: Our bevel gearbox range (10 sizes from 5 kN to 350 kN) enables perfect load equalization across 2-point, 3-point, and 4-point synchronized lifting systems.
4. Safety and Load Holding: Self-locking eliminates need for external brakes, reducing system complexity and cost. Load holds indefinitely without drift, essential for safety-critical applications.
5. Accessories and Support: Protective bellows, limit switches, anti-rotation guides, safety nuts, and stroke indicators simplify installation and ensure reliable operation. AEI provides complete engineered solutions, not just components.
Conclusion
Screw jacks remain the gold standard for industrial lifting, positioning, and load holding because they solve problems that hydraulic and electric alternatives cannot match: perfect load equalization through mechanical linkage, inherent load holding without external devices, and reliable performance across temperature extremes. From solar energy's push toward India's renewable targets to the precision machinery driving manufacturing excellence, AG screw jacks power the nation's industrial growth.
