Jyoti Hydraulic stands among the trusted Worm Gear Screw Jack Manufacturers in India, delivering mechanically robust, safety-driven lifting solutions engineered for critical industrial applications. In mechanical lifting systems, safety is not a feature—it is a fundamental engineering requirement. This is precisely why ISO 6065 plays a crucial role in governing the design, performance, and operational reliability of worm gear screw jacks used across heavy industries.
Worm gear screw jacks are widely used where controlled lifting, precise positioning, and load holding are essential. Industries such as steel plants, power generation, automation, material handling, cement, and heavy fabrication depend on these systems to lift loads ranging from a few hundred kilograms to several hundred tons. Jyoti Hydraulic manufactures worm gear screw jacks in strict alignment with ISO 6065 guidelines, ensuring consistent performance, structural safety, and operational stability under both static and dynamic loading conditions.
Understanding ISO 6065 and Its Importance in Mechanical Lifting
ISO 6065 is an internationally accepted safety standard that specifies design principles, load ratings, and safety requirements for mechanical lifting devices, including screw jacks. Unlike generic manufacturing practices, ISO 6065 introduces a structured engineering framework that ensures lifting equipment performs safely throughout its service life.
For professional Worm Gear Screw Jack Manufacturers, ISO 6065 compliance ensures:
- Clearly defined rated load and test load limits
- Adequate safety factors against mechanical failure
- Controlled lifting and lowering behavior
- Protection against load slippage or sudden descent
This standard is especially critical in worm gear screw jacks because these devices often operate without secondary braking systems and rely on mechanical integrity and self-locking behavior for safety.
What Is a Worm Gear Screw Jack and How It Works
A Worm Gear Screw Jack is a mechanical device that converts rotary motion into linear motion through a worm gear and lifting screw arrangement. When the worm shaft is rotated manually or by a motor, torque is transferred to the worm wheel, which drives the lifting screw to move upward or downward.
Core Characteristics
- High load capacity
- Slow and controlled lifting speed
- Excellent positional accuracy
- Self-locking load-holding capability
Because worm gear screw jacks are often used for static load holding and precise positioning, adherence to ISO 6065 becomes essential to prevent mechanical failure, misalignment, or unsafe operation.
How ISO 6065 Ensures Safe Lifting in Worm Gear Screw Jacks
1. Defined Load Ratings and Safety Margins
ISO 6065 strictly differentiates between:
- Rated Load (Working Load)
- Test Load
- Ultimate Failure Load
This ensures that worm gear screw jacks are never operated at the edge of mechanical failure. Jyoti Hydraulic designs screw jacks with generous safety margins so that the actual failure load is significantly higher than the rated working load. This approach protects equipment from unexpected overloads caused by shock loading, uneven distribution, or operator error.
This is a key reason industries rely on ISO-compliant Worm Gear Screw Jack Manufacturers in India for critical lifting operations.
2. Self-Locking Requirement for Load Holding Safety
One of the most critical safety aspects addressed by ISO 6065 is load-holding capability without reverse motion. Properly designed worm gear screw jacks exhibit self-locking behavior due to:
- Worm gear lead angle
- Surface friction characteristics
- Gear material selection
ISO 6065 ensures that the screw jack will not back-drive under load when power is removed. This eliminates the risk of sudden load drop, making worm gear screw jacks inherently safer than many alternative lifting systems.
Jyoti Hydraulic carefully engineers worm gear geometry and friction parameters to maintain reliable self-locking performance throughout the product’s lifespan.
3. Structural Strength and Fatigue Resistance
ISO 6065 mandates that all load-bearing components must withstand repetitive loading cycles without deformation or fatigue failure. As a responsible Worm Gear Screw Jack Manufacturer, Jyoti Hydraulic uses:
- High-strength alloy steel lifting screws
- Case-hardened worm gears and wheels
- Heavy-duty cast iron or fabricated steel housings
These materials provide excellent resistance to compressive stress, torsional loads, and long-term wear, ensuring structural integrity even in continuous-duty applications.
4. Controlled Lifting Speed and Motion Stability
Sudden or jerky lifting motion is a major safety hazard. ISO 6065 emphasizes smooth, controlled movement during lifting and lowering operations. Worm gear screw jacks inherently provide slow and precise motion, and ISO-compliant design further ensures:
- Stable load movement
- Reduced vibration
- Minimal risk of load swing or misalignment
This is particularly important in applications such as platform leveling, die lifting, and synchronized multi-jack systems.
5. Alignment, Guidance, and Side Load Protection
ISO 6065 also highlights the importance of proper alignment and guidance. Worm gear screw jacks are designed primarily for axial loads. Any side load can reduce safety and service life.
Jyoti Hydraulic provides engineering support for:
- Proper guide mechanisms
- Correct mounting orientation
- Load distribution across multiple jacks
This ensures that ISO safety principles are maintained not just in product design but also in real-world installation.
Why ISO 6065 Compliance Matters for Worm Gear Screw Jack Manufacturers
For reputed Worm Gear Screw Jack Manufacturers, ISO 6065 is more than a standard—it is a commitment to engineering discipline and operator safety. ISO-compliant products offer:
- Predictable and repeatable performance
- Lower maintenance and downtime
- Improved operator confidence
- Global acceptance for export projects
