Mechanical Self-locking Structure
Combined transmission of worm gear and trapezoidal screw. It can automatically lock loads once power stops without external brakes, completely avoiding accidental load falling.
Compact Modular Housing
Integrated cast box combines reducer and lifting unit, small size and light weight. Standard flange mounting holes are reserved for single-unit use or synchronous linkage of multiple jacks.
Multi-drive Compatibility
Supports manual handwheel, direct motor connection and reducer linkage. Screw stroke and load tonnage can be customized for both low-frequency and high-frequency lifting operations.
Stable Heavy-load & Low Noise
Worm wheel made of wear-resistant tin bronze for smooth meshing. Running noise is controlled under 65dB, load range from 0.5 ton to 120 tons with no vibration during lifting.
High Precision Positioning
Uniform screw pitch enables millimeter-level fine adjustment. Lifting stroke is accurately controllable, ideal for machine leveling, platform lifting and mold alignment.
Low Maintenance & Long Service Life
Fully enclosed housing with grease lubrication and dust/rust-proof structure. Only regular grease refilling is required, lower failure rate and maintenance cost than hydraulic lifting systems.
Q: Will the worm gear jack slide down under no load?
A: Standard trapezoidal screw type comes with built-in self-locking, so it won't slip under empty or full load. Ball screw type for high-speed frequent use needs a brake motor for safety.
Q:Are extra parts required for synchronous lifting of multiple jacks?
A: Synchronous drive shafts and bevel gearboxes are enough to realize synchronous lifting without complex electrical control, with stable synchronization accuracy for large lifting platforms.
Q:What industries can this jack be applied to?
A:Widely used in metallurgical equipment, stage lifting, water gates, machine tool leveling, solar brackets, chemical tooling and construction support.
