A worm gear screw jack receives rotary motion through its input shaft. The worm drives a mating worm wheel, and the screw mechanism converts this rotation into linear travel. The relationship between gear ratio and screw lead determines how far the lifting element moves for each input revolution.

Depending on the design, either the screw travels through the jack body or the screw rotates while a travelling nut moves along it. The appropriate arrangement depends on the available space, connection to the load and how rotation is restrained.

For buyers, the practical point is straightforward: input speed alone does not define lifting speed. The gear ratio, screw lead and drive arrangement must be considered together.

Key Features and Practical Benefits

• 25-ton nominal capacity: A capacity designation for selecting heavy-load applications, subject to the manufacturer’s stated operating limits.
• Worm gear transmission: Uses gear reduction between the rotary input and the screw mechanism.
• Controlled linear travel: Supports gradual lifting, lowering and position adjustment within the selected operating range.
• Mechanical actuation: Produces movement through gears and a screw instead of hydraulic cylinder pressure.
• Machine integration: Can be evaluated for installation in lifting assemblies, adjustable equipment and positioning systems.
• Application-based selection: Stroke, speed, mounting and drive requirements help determine the suitable configuration.

The final feature list should correspond to the configuration quoted. Motorisation, brakes, limit switches, protective bellows and other accessories should be specified separately.

Technical Specifications and Ordering Details

Request the approved dimensional drawing before finalising the machine frame, mounting holes or drive connections.

Industrial Applications

A 25-ton worm gear screw jack may be considered for the following applications after checking the operating requirements:

• Heavy assembly fixtures: Adjusting the position of components during assembly.
• Machine height adjustment: Raising or lowering supported machine sections.
• Industrial lifting tables: Providing movement within a guided lifting structure.
• Fabrication equipment: Positioning fixtures and work supports.
• Process machinery: Adjusting equipment sections where controlled linear movement is required.
• Multiple-point lifting systems: Working within an engineered arrangement of interconnected jacks.

Suitability depends on the complete assembly. A lifting platform, for example, also needs an adequately designed frame, guidance system, load connections and drive arrangement.

What Does the 25-Ton Capacity Mean?

The capacity designation is a starting point for selection. It does not mean that every installation can lift the stated load at any speed, stroke or operating frequency.

A long screw under compression may be limited by its resistance to buckling. Frequent movement may introduce thermal limits. An unevenly supported load can also place more force on one jack than expected.

When specifying the product, distinguish between the load that must be moved and the load that must be held stationary. Also confirm the unit basis used for the “25 ton” designation and request the corresponding rated force in the technical documentation.

How to Select the Right Configuration

Start with the actual load. Include the weight of the moving platform, fixtures and attached equipment. For multiple-jack systems, assess how the load is distributed instead of assuming an equal share at every lifting point.

Define the required stroke. State the full travel needed, together with the available retracted and extended space. Longer travel can affect screw stability and installation dimensions.

Set a realistic lifting speed. Faster travel changes the drive requirements and heat generated during operation. Specify how quickly the load must move through the required stroke.

Describe the operating cycle. Occasional adjustment and repeated production lifting place different demands on the mechanism. Provide the duration of each movement and the expected number of cycles per hour.

Check guidance and alignment. The load should act along the intended screw axis. Side forces and overturning moments need suitable external guidance and structural support.

Describe the environment. Dust, moisture, temperature and exposure to process materials can affect lubrication, protective covers and material selection.

Installation and Maintenance Considerations

Correct installation begins with a rigid mounting surface and proper alignment between the jack, drive and moving assembly. Misalignment can introduce unwanted forces, increase operating resistance and accelerate wear.

Follow the supplied instructions for lubrication, inspection and operating limits. Routine checks should cover mounting fasteners, drive connections, screw condition, unusual noise and changes in operating effort. Where fitted, travel limits and protective devices should also be checked.

Do not assume that a worm gear arrangement provides a guaranteed safety lock. Load-holding behaviour depends on the specific design and operating conditions. Applications involving suspended loads require the holding and protective measures specified by the equipment designer.

Frequently Asked Questions

Is this a hydraulic jack?

A worm gear screw jack uses a mechanical gear-and-screw mechanism. The Jyoti Hydraulic brand name does not change its operating principle.

Can it lift 25 tons through any stroke length?

Not automatically. The permissible load must be checked against the selected stroke, screw dimensions, mounting conditions and operating duty. Longer unsupported screw lengths can affect compression capacity.

Can the screw jack be operated with an electric motor?

Motor-driven operation is possible for suitably configured screw jacks. Confirm the available arrangement and required input torque, speed and motor rating for this model.

Is the jack self-locking?

This must be confirmed for the specific configuration. Self-locking should not be assumed solely because the product uses worm gearing. Ask whether the application requires a brake or another holding provision.

Can several jacks lift one platform together?

An engineered system can use multiple screw jacks. Load distribution, mechanical connections, synchronisation and platform guidance must be assessed together.

Is it suitable for continuous operation?

Continuous operation requires an explicit duty rating. Share the expected operating cycle so the mechanism’s thermal and mechanical limits can be checked.

What information is needed to order?

Provide the load, stroke, speed, duty cycle, mounting orientation and drive preference. An installation drawing is particularly useful when replacing an existing jack or building a multiple-point lifting system.
