In modern industrial environments, the demand for safe, efficient, and precise lifting systems has never been higher. Jyoti Hydraulic, a leading manufacturer and supplier of worm gear screw jacks in India, has established itself as a trusted name for heavy-duty lifting solutions. With decades of engineering experience and advanced in-house manufacturing capabilities, Jyoti Hydraulic specializes in designing screw jacks that deliver reliability and control in even the most challenging applications.

Industries such as steel manufacturing, construction, shipbuilding, and material handling frequently require the lifting or positioning of extremely heavy components — sometimes exceeding 100 tons. Handling such massive loads demands equipment that can sustain high stress, maintain precision, and ensure complete operator safety.

This is where Jyoti Hydraulic Worm Gear Screw Jacks excel. Engineered for load capacities up to 200 tons, these screw jacks combine robust mechanical design, advanced materials, and precision machining to offer unparalleled stability and long-term performance.

2. Understanding Heavy Load Applications

A large load application typically refers to any industrial scenario where the weight or force involved exceeds standard lifting equipment capacity — often in the tens or hundreds of tons. Examples include:

  • Lifting molds in steel or foundry plants

  • Aligning heavy presses in manufacturing

  • Raising structural platforms or bridge components

  • Adjusting massive conveyor systems or ship sections

In such high-load operations, stability, accuracy, and safety are paramount. Any sudden movement, imbalance, or vibration could result in equipment damage or safety hazards. Hence, heavy-duty lifting systems require controlled motion, torque multiplication, and self-locking mechanisms to prevent slippage or reverse motion.

Jyoti Hydraulic addresses these challenges by offering custom-engineered worm gear screw jacks designed specifically for large load applications. Each unit is meticulously built to handle extreme loads while maintaining smooth, synchronized lifting operations.

3. Design and Engineering of Jyoti Hydraulic Worm Gear Screw Jacks

The superior performance of Jyoti Hydraulic Worm Gear Screw Jacks lies in their intelligent design and robust construction. Each element is purpose-built to enhance load-bearing capacity, minimize wear, and ensure longevity under continuous operation.

Key Design Elements:

  • High-Strength Worm Gear Mechanism
    The core of the system is a precision-engineered worm and worm wheel, which converts rotational motion into linear motion. The design ensures efficient torque transmission while maintaining smooth motion under heavy loads.

  • Alloy Steel Components
    Critical load-bearing parts such as the lifting screw, worm, and nut are manufactured from hardened alloy steel, providing exceptional resistance to deformation, fatigue, and corrosion.

  • Precision-Machined Threads
    The screw threads are CNC-machined to micron-level accuracy, ensuring consistent pitch and friction characteristics. This precision guarantees controlled motion and minimizes energy loss.

  • Robust Housing Design
    The jack body is made from cast iron or high-grade steel housings, capable of withstanding both axial and radial forces. Reinforced structural ribs further improve mechanical stability.

Each of these design aspects contributes to load-bearing efficiency, operational safety, and extended service life — essential attributes when dealing with capacities between 50 to 200 tons.

4. Working Principle: How Large Loads Are Lifted

The working principle of a worm gear screw jack for heavy loads is based on the conversion of rotary motion into linear motion. Here’s how it works step by step:

  1. Input Motion:
    A motor or manual hand drive applies rotational energy to the worm shaft.

  2. Torque Transmission:
    The worm shaft engages with the worm gear (or worm wheel), multiplying the input torque through the gear ratio.

  3. Linear Motion Conversion:
    The worm gear rotates the lifting screw, which either moves up or down depending on the direction of rotation.

  4. Load Movement:
    As the screw moves, it lifts or lowers the attached load with high precision and control.

  5. Self-Locking Mechanism:
    The friction between the worm and worm wheel provides a self-locking effect, preventing the load from descending unintentionally even when the input power is removed.

Real-World Example:

In a steel manufacturing plant, a 100-ton mold lift system may employ four synchronized Jyoti Hydraulic Worm Gear Screw Jacks. Each jack handles a portion of the total load, working in perfect harmony to ensure uniform lifting without tilt or vibration. This setup allows safe mold positioning and easy maintenance access.
