1-Stage Screw Jack Gearboxes are mechanical devices used to lift, lower, or adjust the position of loads vertically. These gearboxes use a worm and worm wheel mechanism combined with a screw jack to convert rotational motion from an electric motor into the linear motion of the lifting shaft. Thanks to their high lifting capacity and precise stroke control, 1-Stage Screw Jack Gearboxes are widely used in various industrial machinery systems.
Applications of 1-Stage Screw Jack Gearboxes
- Industrial lifting tables: Used for lifting and lowering goods, molds, or equipment in factories with high precision.
- Gate lifting systems: Suitable for irrigation gates, drainage culverts, and flow regulation systems requiring stable operation.
- Height-adjustable conveyors: Helps change the working height of conveyors to suit each production stage.
- Mechanical manufacturing equipment: Used to lift, push, or adjust the position of machine assemblies during machining and assembly.
- Automation lines: Supports adjusting the working position of equipment, sensors, or drive mechanisms in automated production systems.
- Stages and specialized lifting systems: Applied in stage platform lifting mechanisms, working platforms, or equipment requiring vertical up-and-down movement.
Advantages of 1-Stage Screw Jack Gearboxes
- High lifting force in a compact design: With just a single-stage transmission, the device still well meets load lifting requirements in various industrial applications.
- Precise stroke adjustment: Lifting and lowering movements occur stably, suitable for systems requiring high precision.
- Sturdy cast iron housing: Rigid construction helps reduce vibration and increases durability during use.
- Good self-locking capability: Many screw jack series have the ability to hold loads when power is cut off, enhancing system safety.
- Easy installation and maintenance: Simple construction makes inspection, replacement, and servicing more convenient.
- Compatible with various electric motors: Suitable for diverse drive solutions in industry and mechanical manufacturing.
Prices of 1-Stage Screw Jack Gearboxes at Thanh Thai Motor
The prices of 1-Stage Screw Jack Gearboxes depend on the lifting load, working stroke, transmission ratio, and motor power used. Below is the price list for some 1-stage screw jack models distributed by Thanh Thai Motor for your convenient reference and selection of suitable products.
Criteria for Purchasing 1-Stage Screw Jack Gearboxes
- Determine the lifting load required: This is the most crucial parameter to select the correct 1-stage screw jack capacity and ensure safe equipment operation.
- Select the appropriate lifting stroke: It is necessary to determine the actual lifting height to choose a screw jack type with a stroke meeting application requirements.
- Desired lifting speed: Working speed directly affects the selection of transmission ratio and motor power.
- Installation conditions: Working space, installation orientation, and machine frame structure must be checked before selecting the product.
- Choose suitable motor power: Too small a motor may lack lifting force, while too large a motor increases unnecessary investment costs.
- Operational safety: For systems that lift loads frequently, prioritize models with good self-locking capability and high stability.

Frequently Asked Questions
What type of screw jack should be chosen for a 1-ton load lifting table?
In addition to the 1-ton load, it is necessary to determine the lifting height, number of lifting points, and desired lifting speed. For large lifting tables, in many cases, 2 to 4 screw jack sets operating synchronously are used.
Why does the lifting speed of a screw jack slow down after running for a period of time?
The cause usually comes from a lack of lubrication, insufficient motor power, overloading beyond the allowable limit, or worn-out transmission components after prolonged use.
Can a single motor drive multiple screw jacks?
Yes. In practice, many lifting table or platform systems use a single motor combined with a drive shaft to operate multiple screw jack sets simultaneously.
Should you choose a screw jack or a hydraulic cylinder?
If precise positioning, stable load holding, and minimal oil system maintenance are required, a screw jack is usually the appropriate choice. Meanwhile, hydraulic cylinders are typically preferred when fast lifting speeds or very large loads are needed.
