Heavy-duty electric railway lifting jacks are specialized, high-capacity systems designed for the safe and synchronized lifting of trains, locomotives, and wagons during maintenance and assembly. These jacks are often sold in sets of four or more columns and feature advanced control systems and safe   Read More>

Screw jacks are a popular choice for achieving height adjustments in crank tables, offering several advantages. Note: Self-locking screw jacks do not require a separate locking mechanism to hold the table at a desired height. However, some worm gear ratios may require an additional locking mechanism to prevent creep, especially when using handwheels. Multiple screw jacks can be used in tandem with connecting shafts and couplings to provide synchronized lifting.   Read More>

Screw jacks are a type of mechanical power transmission equipment that can be used for stage lifting platforms. They provide linear motion and can be used for lifting, pushing, pulling, or applying pressure. Theatre, orchestra, dance and other forms of performed arts typically utilise elevated stages during performances. Screw jacks are a popular choice for stage lifts due to their characteristics. They provide stable support for the stage, orchestra pits, equipment, and seating platforms.   Read More>

For a glass packaging machine requiring a screw jack system to raise and lower a carriage clamping mechanism, a synchronized ball screw jack system is the ideal choice. This configuration ensures precise, simultaneous movement of multiple screw jacks, which is crucial for handling the delicate and continuous production demands of glass manufacturing. this application uses four screw jacks in an H-configuration and incorporates a high-performance gear set to meet speed and duty cycle requirements.   Read More>

Screw Jack Lifting Mechanism Is Used in Airport Passenger Walkways (also known as jet bridges or passenger boarding bridges) to adjust the height and angle of the ramp, allowing it to align precisely with the doors of various aircraft. These systems provide the precise, controlled, and heavy-duty lifting required for this application. multiple screw jack systems can be synchronized to operate in unison, ensuring the cab of each walkway aligns perfectly with its respective aircraft door.   Read More>

Linked Vertical Lead Screw Jacks Work in Scissor Lifts to provide the precise linear motion needed for lifting and positioning heavy loads. A series of screw jacks can be linked and driven by a single motor to ensure synchronized lifting across the entire platform. This setup provides a safe, reliable, and mechanically synchronized lift compared to single-point hydraulic or manually-operated systems. Components: The primary components are a worm gear and a threaded screw.   Read More>
