Products Description
Corrosion Resistant Screw Jack is a heavy‑duty lifting actuator specially developed for highly corrosive working conditions. It adopts a worm‑and‑worm‑gear mechanical transmission structure to realise stable heavy‑load jacking and displacement adjustment. Constructed with corrosion‑resistant materials and special protective processes, the product can operate stably over the long term in harsh environments such as humid conditions and acid‑alkali mist with low risk of rusting and jamming. It is widely applied in special industrial sectors including chemical engineering, marine engineering and wastewater treatment, providing safe and reliable lifting support for various heavy‑duty equipment.
Product Advantages
Outstanding Corrosion Resistance
All media‑contacting parts of the unit undergo enhanced anti‑corrosion treatment, so they resist rust even during long‑term operation in acid‑alkali and humid environments.
Reliable Mechanical Self‑locking
Equipped with mechanical self‑locking capability, the unit holds its position for extended periods after jacking is complete, eliminating safety hazards caused by unintended load dropping.
Smooth and Stable Transmission
Precise, uniform meshing between the worm and worm gear enables impact‑free, jitter‑free jacking. Movements remain stable and controllable even under heavy‑load conditions.
Excellent Load‑bearing Capacity
Sufficient structural strength margin supports stable long‑term operation under rated heavy loads and prevents structural deformation or component damage.
Working Principle
Input power drives the worm to rotate. Power transfers to the mating worm gear via tooth‑surface meshing to complete the first‑stage speed reduction and torque amplification.
The worm gear converts rotary motion into linear motion of the screw rod, driving the top load‑bearing platform to achieve steady jacking action.
Once power is cut off, the self‑locking meshing feature of the worm‑and‑worm‑gear set locks the screw rod, keeping heavy loads firmly at the target height.
For reverse operation, power input controls the slow, constant‑speed descent of the screw rod to avoid rapid falling of heavy loads.
This fully mechanical transmission structure requires no complex hydraulic components and rules out medium leakage risks in corrosive environments.
Application Scope
Chemical Equipment
Suitable for lifting and adjustment of reactors, tanks and other equipment in chemical workshops to resist erosion from on‑site acid‑alkali mist.
Marine Engineering
Applied for equipment jacking and maintenance on offshore platforms and ship decks, capable of withstanding harsh salt‑spray and high‑humidity operating environments.
Wastewater Treatment
Used for aeration equipment and gate adjustment in wastewater treatment plants, resistant to wastewater and corrosive chemical agents.

Precautions
Never operate beyond the rated load capacity. Overloading will trigger structural deformation and permanent damage to core transmission components.
Do not exceed the designed maximum travel limit. Forced contact with travel end stops may lead to screw‑rod disengagement or housing cracking.
Do not stand underneath lifted heavy loads during operation. Even with self‑locking features in place, adequate safety protection must be implemented to prevent accidents.
Avoid direct spraying of corrosive media onto the unit surface, as this will damage outer protective coatings and accelerate component corrosion.
Non‑professional personnel shall not disassemble the sealed cavity. Disassembly will destroy protective sealing structures and drastically reduce corrosion‑resistant performance.
FAQ
Q: Can Corrosion Resistant Screw Jack be used long‑term in strong‑acid environments?
A: Models with matching corrosion‑resistance grades are suitable for strong‑acid working conditions. Simply inform us of the medium type in advance, and we will configure the corresponding protection solution.
Q: Will the jack slip down automatically during lifting?
A: The unit comes with built‑in mechanical self‑locking. It can hold position for a long time after power is cut off, and unintended load dropping will not occur.
Q: Does Corrosion Resistant Screw Jack require regular replenishment of special lubricant?
A: The internal transmission chamber is pre‑filled with special grease tailored for corrosive environments. Frequent replacement or refilling is not required under normal operating conditions.
