Stainless Steel Screw Jack System for Corrosive Environments

Q: What is the load capacity range for this corrosion-resistant jack?
A: This series is available in capacities from 5 tons to 30 tons. While slightly lower in maximum capacity than some heavy-duty carbon steel models, its primary strength lies in its material composition for harsh environments.

Q: What lifting height can be achieved?
A: The standard lifting stroke is up to 2800 mm, which is sufficient for most tank lifting, shimming, and alignment tasks in industrial settings.

Q: What materials are used to ensure corrosion resistance?
A: The housing and critical external components are manufactured from 304 or 316 Stainless Steel. The lifting screw is often made from stainless steel or carbon steel with a corrosion-resistant coating like zinc-nickel plating, depending on the specific corrosion requirements.

Q: What are the key features of this jack?
A: The standout features are:

• Excellent Corrosion Resistance: Ideal for use in chemical plants, food & beverage processing, marine applications, and outdoor environments.

• Hygienic Design: Smooth surfaces and stainless steel construction make it easy to clean and suitable for industries with high hygiene standards.

• Mechanical Reliability: Retains the core benefits of a screw jack: self-locking safety, stability, and precise control.

• Sealed Options: Available with protective boots or seals to guard internal mechanisms from moisture and contaminants.

Q: What is the main advantage of choosing this type?
A: The overwhelming advantage is its long service life and reliability in corrosive and washdown environments. It prevents rust and degradation, ensuring the lifting equipment remains operational and safe where standard jacks would fail prematurely.

Q: What are its specific applications in tank lifting?
A: It is specifically used for:

• Lifting tanks in chemical processing plants and pharmaceutical facilities.

• Handling tanks containing acids, alkalis, or other corrosive substances.

• Maintenance in food and beverage, brewing, and water treatment plants where equipment must withstand frequent washing and exposure to moisture.

• Any tank lifting application in a marine or coastal environment.
