A Screw Jack is a mechanical device used for lifting heavy loads with precision and control. It operates on the principle of a screw mechanism, converting rotational motion into linear movement. This makes it ideal for applications requiring stable and reliable lifting, such as in construction, manufacturing, and automotive industries. Our screw jacks are designed with durability and efficiency in mind, ensuring long-term performance even under demanding conditions.
| Model | Load Capacity (tons) | Lift Height (mm) | Weight (kg) | Material |
|---|---|---|---|---|
| SJ-100 | 10 | 200 | 5.2 | Stainless Steel |
| SJ-200 | 20 | 300 | 8.7 | Carbon Steel |
| SJ-500 | 50 | 400 | 15.3 | Alloy Steel |
| SJ-1000 | 100 | 500 | 25.0 | Hardened Steel |
Screw jacks are versatile tools used in various sectors. In construction, they support structures during assembly or repair. In manufacturing, they position heavy machinery with accuracy. Automotive industries utilize them for vehicle lifting and alignment. Additionally, they are common in stage setups for entertainment events and in agricultural equipment for adjustments. Their reliability makes them a preferred choice for engineers and technicians worldwide.
What is the maximum load a screw jack can handle?
Our screw jacks are rated for loads up to 100 tons, depending on the model. It is crucial to select the appropriate model based on your specific requirements to ensure safety and efficiency. Always refer to the product specifications for detailed load ratings.
How do I maintain a screw jack to ensure longevity?
Regular maintenance includes lubricating the screw mechanism every 3-6 months, inspecting for wear or damage, and cleaning to prevent dirt buildup. Use recommended lubricants as per the manual. For heavy usage, more frequent checks are advised to avoid failures.
Can screw jacks be used in outdoor environments?
Yes, many of our screw jacks are made from corrosion-resistant materials like stainless steel, making them suitable for outdoor use. However, it is important to protect them from extreme weather conditions and perform routine maintenance to prevent rust and ensure optimal performance.
What safety precautions should I take when using a screw jack?
Always ensure the load is within the jack's capacity, use on a stable and level surface, and avoid standing under the load during operation. Regularly check for any signs of damage or wear. Follow the manufacturer's guidelines and use personal protective equipment as necessary.
Are custom screw jacks available for specialized applications?
Yes, we offer customization options for screw jacks, including specific load capacities, lift heights, and materials. Contact our engineering team with your requirements, and we can design a solution tailored to your needs, ensuring compatibility and reliability.
How does a screw jack compare to hydraulic jacks?
Screw jacks provide more precise control and do not require hydraulic fluid, reducing maintenance and leak risks. They are ideal for applications where stability and accuracy are paramount. Hydraulic jacks might offer faster lifting but can be less precise and require more upkeep.
What is the typical lifespan of a screw jack?
With proper maintenance, our screw jacks can last for many years, often exceeding 10 years under normal operating conditions. Factors such as load frequency, environment, and maintenance practices influence the actual lifespan. Regular inspections help maximize durability.
