Jyoti Hydraulic, a trusted leader in hydraulic and mechanical motion control solutions, plays a vital role in supporting India’s rapidly expanding industrial landscape. As industries grow and automation becomes essential, the need for safe, efficient, and precise heavy lifting systems has increased significantly. In India’s high-demand manufacturing environment—where accuracy, reliability, and worker safety are top priorities—worm gear screw jacks have become one of the most dependable and cost-effective lifting technologies. Designed to deliver long-term performance under tough and variable industrial conditions, the high-precision worm gear screw jacks manufactured by Jyoti Hydraulic are engineered specifically to handle the challenges of Indian factories, plants, and construction sites with exceptional stability and durability.
- What Exactly Is a Worm Gear Screw Jack?
A worm gear screw jack is a mechanical lifting device that converts rotary motion into controlled linear movement. It consists of a worm shaft and worm gear, a lead screw, and a robust housing that supports thrust loads. When rotational force is applied either manually or through an electric motor the screw moves upward or downward, creating a precise lifting motion.
Core Components
- Worm Shaft – Transfers input torque from motor/handle.
- Worm Gear – Meshes with worm shaft for torque multiplication.
- Lead Screw (Lifting Screw) – Moves linearly to carry the load.
- Thrust Bearings – Support heavy axial forces.
- Protective Housing – Shields internal mechanisms and provides durability.
- Top Plate / Flange / Nut – Interface for load attachment.
How It Works
Worm gear screw jacks operate on the basic principle of mechanical advantage.
The worm gear’s high reduction ratio allows it to move heavy loads using relatively low input torque. Unlike direct hydraulic lifting, screw jacks rely on controlled mechanical motion, which enhances stability and precision.
- Why Worm Gear Screw Jacks Are Perfect for Heavy Lifting in India
India’s industrial ecosystem requires lifting equipment that is:
- Easy to maintain
- Safe for daily operations
- Affordable and energy efficient
- Capable of performing in harsh environments
Worm gear screw jacks fulfill all these criteria making them extremely popular across steel plants, automotive units, construction sectors, power industries, and more.
2.1 High Load Handling Capacity
Modern worm gear screw jacks especially those designed by Jyoti Hydraulic can lift loads ranging from:
- 0.5 Ton
- 5 Ton
- 25 Ton
- 50 Ton
- Up to 100+ Ton (custom-built)
This broad load range makes them suitable for industries that require both precision lifting and heavy-duty positioning.
2.2 Self-Locking Safety Advantage
One of the most important advantages is the self-locking capability.
Due to the worm gear design, the load cannot back-drive the system. This prevents accidental lowering a critical safety factor for heavy lifting operations in India.
Self-locking eliminates the need for:
- External brakes
- Additional locking devices
- Emergency load-holding mechanisms
2.3 Precision Movement and Control
With screw-based linear motion, worm gear screw jacks offer:
- Millimeter-level accuracy
- Smooth vertical and horizontal movement
- Zero vibration lifting
- Excellent repeatability
This is extremely beneficial for applications such as:
- Die lifting
- Conveyor height adjustment
- Assembly line automation
- Structural alignment
2.4 Low Maintenance and Long Life
Unlike hydraulic systems which require seals, oil checks, and periodic leakage inspection, screw jacks have:
- Minimal moving parts
- No hydraulic fluid
- No complex maintenance requirements
They provide long-term operational reliability with only basic lubrication.
2.5 Suitable for Indian Industrial Conditions
India has diverse industrial environments including:
- High temperatures
- Dusty conditions
- Humid coastal areas
- Heavy-duty continuous operations
Worm gear screw jacks are engineered to perform efficiently even under these challenging operating conditions.
- Major Types of Worm Gear Screw Jacks Used in India
India’s industrial sector primarily uses three types of screw jacks, each designed for different lifting motions.
3.1 Translating Screw Jack
- The screw travels linearly while the body is stationary.
- Ideal for vertical lifting operations.
- Common in steel plants, automotive lines, and factory automation.
3.2 Rotating Screw Jack
- The screw rotates but does not travel.
- The load moves with the help of a travelling nut.
- Best for long-stroke and high-speed applications.
3.3 Travelling Nut Screw Jack
- The lifting nut moves while the screw rotates in a fixed position.
- Ideal for environments where the load travel must be controlled precisely without exposing the screw.
- Detailed Industrial Applications in India
Worm gear screw jacks are used in nearly every heavy-duty sector due to their versatility, precision, and cost-effectiveness.
