A transmission mechanism is gradually expanding its market share, replacing hydraulic and pneumatic transmissions. It's compact, low-noise, carries heavy loads, and can be self-locking, making it more convenient and easier to operate. I bet you've guessed it, right? This is our main character for today.——Screw Jack（Spiral Hoist）。

Screw JackMuch of its benefit is attributed to its internal structure—the worm gear arrangement. This structure was previously used in reducers to slow down rotation while increasing torque, meaning it can transmit a large torque with very little force. Later on, people discovered that it's also an excellent choice for lifting or hoisting mechanisms in elevators, soScrew JackIt was born out of necessity.

ZA (Trapezoidal Threaded Rod Type)Screw jack with worm gear is a fundamental lifting component featuring a compact structure, small size, light weight, versatile power source, noiseless operation, easy installation, flexible usage, diverse functionalities, multiple mounting options, high reliability, and long service life.，Widely applied in industries such as machinery, metallurgy, construction, and hydraulic equipment, featuring numerous functions including lifting, lowering, propulsion, flipping, and height adjustment with auxiliary components.. Can be used individually or in combination, accurately controlling and adjusting the lifting or propulsion height according to a set program, powered by an electric motor or other power source。It comes in various structural and assembly configurations, and the lifting height can be customized according to the customer's requirements.。

ZAType (trapezoidal screw type) is suitable for low-speed, low-frequency applications., The main components include: precision trapezoidal screw and high-precision worm gear sets.Economic:Compact structure, easy operation, convenient maintenance；Low speed, low frequency: mainly used in high-load, low-speed applications that do not require frequent operation；Maintain Load: The trapezoidal screw features an automatic locking function, which can maintain the load even without a braking device. Note:In the event of significant vibration or impact loads, the self-locking function may fail. Please add an external braking device.
