Our stainless steel heavy-duty screw jack is a robust mechanical lifting and positioning device engineered specifically for harsh corrosive working environments and heavy-load industrial lifting tasks. Different from ordinary carbon steel screw jacks prone to rust and oxidation, this full upgraded stainless steel lifting unit delivers stable vertical lifting, precise height adjustment, synchronous lifting and static load holding performance without extra protective coating. It supports both manual handwheel drive and electric motor drive modes, featuring built-in self-locking function to prevent accidental load slipping during long-term static positioning. Ideal for industries that require both heavy load capacity and full corrosion resistance, this heavy-duty screw jack minimizes maintenance frequency and extends overall service life drastically.
 

We adopt premium 304/316 stainless steel for all external housings, lifting screws, worm shafts and connecting accessories, bringing unparalleled material performance compared with conventional painted steel screw jacks:

Excellent Corrosion & Rust Resistance: Resist erosion from seawater, acid mist, alkaline liquid, humidity, salt spray and chemical vapors. No surface rust, peeling paint or metal oxidation even in long-term wet outdoor and chemical workshop working conditions.

High Sanitation & Easy Cleaning: Smooth integrated stainless steel surface leaves no residue, dirt or bacterial growth. Fully compliant with strict hygiene standards for food processing, pharmaceutical and beverage production lines.

Strong Mechanical Toughness & Wear Resistance: The whole stainless steel structure maintains stable structural strength under continuous heavy load impact, avoiding deformation, fracture or fatigue damage under frequent lifting cycles.

Zero Surface Maintenance Cost: No need for regular repainting, anti-rust oil spraying or surface maintenance. Reduce later operation and maintenance costs and downtime effectively.

High & Low Temperature Adaptability: Works stably in ultra-low temperature cold storage and high-temperature humid workshops without performance attenuation or material embrittlement.

This heavy-duty stainless steel screw jack is customized for harsh and sanitary industrial scenarios where ordinary lifting equipment cannot work normally. Main applicable fields are listed below:

Marine & Offshore Industry: Deck equipment lifting, ship platform height adjustment, offshore equipment positioning, fully resistant to marine salt spray corrosion.

Food & Beverage Processing: Production line lifting bracket, conveyor height adjustment, food packaging equipment positioning, meeting food-grade sanitary requirements.

Pharmaceutical & Biochemical Industry: Laboratory precision lifting, pharmaceutical production line equipment adjustment, anti-corrosion against chemical reagents and sterile workshop environment.

Water Treatment & Sewage Engineering: Water gate lifting, filter equipment height adjustment, underwater working supporting components.

Chemical Factory Workshop: Anti-acid and anti-alkali equipment lifting, chemical reaction kettle positioning, adapting to volatile corrosive gas environment.

Cold Storage & Humid Workshop: Low-temperature logistics equipment lifting, constant humidity industrial workshop mechanical positioning.

This screw jack adopts integrated worm gear transmission structure with optimized internal layout, achieving high transmission efficiency, stable operation and reliable self-locking performance. All core internal components are matched with anti-corrosion treatment to fit the overall stainless steel design:

Stainless Steel Worm Shaft: Integral formed stainless steel worm shaft with high machining precision, smooth meshing operation, low running noise and strong torsion resistance under heavy load.

High-Strength Bronze Worm Gear: Wear-resistant tin bronze worm gear is adopted for friction matching, greatly reducing gear wear during long-term continuous operation and improving transmission stability.

Self-Locking Trapezoidal Lifting Screw: High-precision trapezoidal stainless steel screw features excellent static self-locking performance. It can lock the load firmly at any stroke position without external braking device, avoiding safety risks caused by load falling.

Sealed Integrated Housing: Fully sealed stainless steel housing prevents moisture, dust, chemical vapor and liquid from entering the internal transmission structure, protecting core parts and prolonging service life.

High-Precision Wear-Resistant Bearings: Matched with anti-corrosion bearings to reduce running friction, ensure smooth linear lifting movement and reduce long-term operating loss.

The whole structure features compact size, easy installation, no complex auxiliary configuration, and supports upright installation, inverted installation and horizontal installation according to on-site working demands.

Our stainless steel heavy-duty screw jack covers full segmented load specifications to match different heavy-load and micro-precision lifting demands. All load grades support customized stroke length, gear ratio and installation method without fixed model restrictions. The detailed load performance parameters are shown in the table below:
